An E cient Route Optimization Using Ticket-Id Based Routing Management System (T-ID BRM)


 MANET – Mobile Ad Hoc Network is the connection of several remote mobile nodes. These networks are dynamic and independent to move anywhere. It does not contain any central controller, and hence it is stated as a structure less network. MANET is one of the most emerging technologies getting popular in recent days. It's significant features, and real-time issues grab the research community's attention towards it. The unstable data transmission will leverage the overall network performance, and designing an energy-efficient routing protocol is challenging. The main reason for this problem is the lack of a stable multipath routing system and resource constraints. Various research works have launched several efficient routing mechanisms, but the need for advancement still exists. In this paper, we propose a Ticket –ID Based Routing management system for enabling reliable routing for the entire network. The proposed system work under the TID principle, which executes according to the node properties and routing maintenance system. This system works under the supervision of TID- Routing manger. The TID routing manager is responsible for managing the ticketing pool and allocating unique ticket-ID based on the collected node factors such as energy, node location, speed, etc. The proposed routing system facilitates the shortest path for reliable communication. An experimental work using NS- simulator is done with the proposed method. The proposed work's efficiency is determined using a comparison work between T-ID BRM with TABRP, OGFSO, and PDMR. The observation states that the proposed Ticket-ID system achieves 94% better than other existing methods.


Introduction
MANET the advancement of wireless networks and the backbone of communications. In recent years the technology impact has more significant influence in every field. These features and on-demand services raise the demand for flexibility and reliability in the working environment. It gives birth to mobile computing. Mobile computing is the most prominent way for communication. Especially MANET, it is a self-configured network without any central controller or infrastructure. MANET can travel at a rapid speed in any direction in an excellent way. The dynamic multihop wireless ad hoc communication network enables ceaseless internetwork between one another without any preexisting infrastructure.
In MANET's primary concern is energy usage, power limitation, bandwidth limitation, and range limitation. The nodes forward the packets from source to destination through a linked connection. But the major challenge is finding the shortest path. In MANET, communication protocols play an essential role, enabling the network by connecting the nodes. For an effective and reliable packet delivery, the MANET network should maintain the QoS metrics.
In MANET, each node consumes more energy, and at a stage, a particular node's energy level gets depleted. It results in node failure [1]. Based on this, several routing protocols are evolved, such as destination-sequenced distance vector (DSDV), dynamic source routing (DSR), location-aided routing (LAR, and the ad-hoc on-demand distance vector (AODV). But these are developed for single-path routing. Multipath routing mechanism such as least standard multiple-based routing (LCMR), Fibonacci multipath load balancing (FMLB) routing, Multicast ad-hoc ondemand distance vector (MAODV), and location prediction-based routing (LPBR) [2][3][4][5][6][7][8], etc.overcomes the drawbacks of single-path routings. Even though several works evolved in improving the MANET performance, still the routing issues exist. It highlights the importance of effective path maintenance mechanisms. Multicast routing is a popular technology mostly in establishing collaborative communications and video conferencing [9]. Multicast routing minimizes the time, delay, and bandwidth consumptions. Generally, the MANET routing protocols are three types: reactive protocols, proactive protocols, and hybrid protocols.
The reactive protocols maintain memory section routing tables, and these memories no need for frequent updates. The reactive protocol enables the route with a short time and low latency. The proactive protocol allows control packet exchanges between the nodes, and their details are updated frequently in the routing tables. The proactive routing process is more effective as it contains accurate and updated routing information. The combination of both reactive and proactive routing protocols is known as the hybrid protocol. Therefore, in this paper, we propose a Ticket -ID Based Routing management system (T-ID BRM) for enabling efficient routing in MANET. The TID routing principle with the TID routing manager works effectively in improving the network energy and shortest path for overall communications. The proposed work's significant contributions are listed below;  Initially, a network is deployed.  Integrating Ticketing system with Ticket routing manager  Applying T-ID BRM protocol for obtaining nodes and network information exactly  The shortest path is decided based on the node's location, energy level, and neighbor table information.  The routing maintenance system is introduced.  Finally, the data communication between the nodes and network performance is analyzed. This paper is organized as follows; section 1 consists of the introduction. Section 2 has various related work regarding MANET. Section 3 contains the proposed system with architecture and working methodologies. Section 4 contains the result and discussions. Finally, section 5 contains the conclusion part.

S. J. Sultanuddin et al. [10] proposed TABRP (Token Agent-Based Routing protocol)for MANET. In this work, the author introduced a token-based system with a token agent. The entire mechanism functioned under the supervision of this token agent. The reason for introducing this token is collecting the node's activity information and updates to the token agent. TABR establishes the shortest path based on the collected data. TABR is suitable for typical applications and multimedia applications.
Rajasthani et al. [11] introduced an energy-aware optimized link state routing (EA-OLSR) protocol using clustering with the OGFSO algorithm. This proposed work addressed the energy consumption issues in MANET. Initially, a cluster is formed from the deployed network, and a limited energy consumption-based multipath routing system is enabled. Next, an opposition genetic-based fish swarm optimization algorithm is implemented. This mechanism improves the energy level and network lifetime.
Premanand et al. [12] discussed the network's unstable nodes' data accuracy issue. To overcome this, the author proposed Enhanced Data Accuracy based Path Discovery (EAPD) technique. This approach selects the path with maximum data accuracy for node communication and rejects the minimum data accuracy paths. The backing route selection algorithm controls the intrusion during the communication period. From the observation, it results that this approach minimizes the packet drop rate and energy consumptions. Arindrajit Pal et al. [13] proposed a prediction-based multipath routing protocol. The author initiated this work in identifying the stable neighbors in the MANET. For this, the author discovered a regular multipath route. It achieves a minimum delivery ratio comparing to other existing works.
R. Shanthy et al. [14] discussed the inefficient routing challenges in MANET. The author incorporated the traditional zone routing protocol (ZRP) and enhanced it with a sleep scheduling mechanism. The concept is every node in the network is grouped into zones and select a zone leader among them. The Zonal leader is responsible for choosing the multipath from source to destination. This approach results in better throughput and packet delivery ratio.
Rajendra Prasad et al. [15] disclosed that an energy-efficient routing protocol would maximize network performance. Designing an efficient routing protocol for MANET is a challenging task. The author proposed an energy-aware on-demand routing protocol. The performance proves superior in the aspect of energy consumptions.
Anand et al. [16] proposed an energy-efficient channel aware ad-hoc on-demand multipath distance vector routing protocol. This EECA -AOMDV fulfills MANET's major three requirements, such as energy effectiveness, unwavering quality, and dragging out system lifetime. This approach minimizes the maximum time spends during path choosing.
OladayoOlufemiOlakanmi et al. [17] proposed a mobility and energy prediction model for enabling an efficient routing system in the mobile wireless sensor network. It provides high accuracy about the node's mobility and residual energy, which results in optimal route paths. This predictive model is more effective in obtaining the sink nodes securely.
Dipika Sarkar et al. [18] addressed the drawback of selecting the optimal path in MANET. For this, the author proposed Enhanced-Ant-AODV for effective path selection. This approach combines the Ad-hoc On-Demand Distance Vector (AODV) protocol with Ant Colony Optimization (ACO) for enhancing the networks QoS (Quality of services). According to which pheromone path value obtained using end to end path reliability, nodes residual energy, congestions, and hops. The pheromone path value selects the acceptable route for data delivery.
Lenin Guaya-Delgado et al. [19] discussed the selfish nodes in the network which does not cooperate on task execution. Thus requires a better path with the volunteer nodes to cooperate. For this, the authors developed a novel dynamic reputation-based source routing protocol for MANET. A better path is chosen based on the assigned node's reputation value. Compared to the selfish nodes in the network,cooperative nodes result in a minimum packet loss ratio during transmission.
Several works discussed the routing protocol for MANET. Three mechanisms, such as TABRP, EA-OLSR, and PDMRare taken for comparison. Let's examine those algorithms in detail.

TABRP
(token agent-based route planning protocol): As the name itself specifies, the token agent plan the routing path. The token agent is also known as the token manager, is the major component of this model. The other features of this model are the token pool and token generation system. Initially, once the network is formed, the token manager assigns a token ID to every node. The broadcast Route Request (RReq) message process states the active and sleeping node in the network. All the node activities are under the supervision of the token manager. Every node details such as energy, node location, speed, etc. are updated regularly to the token manager. Based on the provided details, and the token manager plans an efficient routing path.

(Opposition genetic-based fish swarm optimization protocol):
This mechanism also includes energy-aware optimized link state routing (EA-OLSR) protocol. The EA-OLSR protocol concentrated on power consumption during packet transmissions. The proposed work provides reliable routing for the clustering nodes. Initially, on the cluster network, various nodes presented are represented as cluster members. Among which cluster head is selected based on the energy level of the nodes (cluster member). A cluster formed using the K-medoid clustering model. The overall combination provides a greater lifetime with minimum energy consumptions.

PDMR
PDMR refers to the prediction-based multipath routing protocol. This approach consists of two stages in the initial stage, finding of stable neighbor node and the path. In the second stage, the ERNN (Elman Recurrent Neural Network) model predicts future behaviors of neighboring nodes. The ERNN model consists of four layers: the input layer, recurrent layer, hidden layer, and output layer. These layers update the network parameters and predict the original output value. Based on the expected value, the proposed system enables several parallel paths for communications. This mechanism minimizes the major MANET's drawback link fault.

PROPOSED SYSTEM
Multipath routing facilitates multiple routes between the source and destination node. It maximizes successful packet delivery in case the failure occurs in a particular path. Multipath routing consists of three components, such as route discovery, route maintenance, and traffic allocation. Multipath routing achieves load balancing by spreading the traffic among the multiple routes. Multipath routes are easy to discover and enable packet reordering. The major drawback of multipath routing protocol is complexity and overhead. In traffic allocation, the choice of allocation quality is more important. We propose, Ticket -ID Based Routing management system (T-ID BRM). In this mechanism, The TID protocol enhances the multicast routing system, especially in handling the traffic and bandwidth allocation throughout the network. Even though several works are initiating enhanced routing, some details about the sleeping node, whether its presence will affect the network performance or not, are not clearly stated in the existing works. The salient features of our proposed system are;  The proposed system balances the bandwidth allocation according to the application type, which ensures reliable bandwidth throughout the network.  It is suitable for large scale mobile ad hoc networks.  There is no routing priority, which means no nodes acquisitive behavior.  It works under a single protocol; there is no way for confusion during routing  The ticketing system chooses the path at limited time and energy consumption.  Minimum energy consumption maximizes the network lifetime.  Execution under optimal results on low end-to-end delay The below section clearly states the proposed architecture 3.1 Proposed Architecture: The proposed architecture's significant components are network model, ticket-ID routing manager, ticketing pool, and route planning. Initially, the proposed system deployed a network with a set of nodes. The T-ID BRM is the heart of the proposed model. In which the ticket routing manager is responsible for overall network performance. Once the network, all the nodes are registered. The ticket ID manager disputes a unique ticket ID from the ticket pool to all the nodes. This unique ticket-ID observes each node's activities, which and used for future purposes. The next step in this mechanism is to identify the active nodes and idle or sleeping nodes in the network. The active nodes are only eligible for packet transmission. The idle nodes qualify on occasion at the time of changing its state from inactive to active. The ticket-ID manager keenly monitors this observation. The Ticket-ID based routing protocol determined nodes active or idle form, and a clear explanation given in the below section TID system. The TID collected details are categorized and updated into a cooperative node list and inactive node list. The active nodes are coming under the cooperative list, and the idle node is coming under the idle node list. Based on this information, the ticket-ID manager organizes the ready nodes to participate in the network.
Based on the information provided by the TID routing protocol, the neighboring nodes are selected, and the shortest path is chosen. The nodes distance is calculated based on the node distance information provided to make the decision. Another condition is the node energy level; it is also precisely determined based on the provided information. Then the route availability is checked whether it is available or busy. It can be calculated based on task size and distance, such as for larger tasks with the length the traffic is high, and that route is busy. So automatically, the minimum task with length will be avail with available routes for faster execution. In our research, the core of the proposed concept is ticket-ID based routing protocol(TID). The ticket-ID manager work based on the information provided by the TID. The TID protocol has two major components, such as Node property-based and routing maintenance, as shown in figure2. Once the network, the ticket-ID manager labels each node with a unique ticket ID. Based on the ticket ID, the active neighboring nodes are identified and updated. Those identified nodes send a "hello" message to the neighboring node. The neighboring node which receives the message will acknowledge, thus proves that these two nodes are active. These nodes are then coming under the active node with value 1 and updated in the cooperative node list. The node that does not respond is awarded 0 value, stating it is idle state updated in the idle node list. This status can change on future occasions the idle node can acknowledge the hello message and comes under an active node with value 1. This process occurs vice versa, and the status is updated regularly on the node's listing tables. Additionally, based on the unique ticket-ID, the mobile node's properties like distance, speed, location, and energy are calculated and updated in the listing table.
In MANET, routing protocols are essential for executing network performances. Here the TID protocol decides the routing plan and updates to the ticket-ID manager. The routing path is established between the source to destination via neighboring nodes as interfaces for packet transmission. As mentioned in figure 2, the route management system is responsible for discovering a newer efficient route to reach the destination. Then the ticket-ID manager allocates the appropriate path according to the application type. The transmission process is processed with sender node . The transmission begins from the source and ends at the destination; here the intermediate nodesact as routers. These nodes are a dynamic model which free to move anywhere within the transmission range R . Each node has a unique ticket-ID provided by the ticket-ID manager and the tickets } , The characteristics of the network model are;  Mobile nodes are independent of idle or move anywhere.  Nodes are free to join or leave, with no particular entering or leaving conditions.  The ticket-ID manager supervises the nodes joining or leaving. the node properties such as nodes speed, location, energy, distance, bandwidth are collected and updated by TID to the ticket-ID manager.

communication with the admin of ticket-id manger
The node state is categorized into active node, then case iii is processed, such as collecting the active node status and update its ticket-id history. In case the response is idle, then it is organized under idle node status with its ticket-id. Finally, the node with the active state is ready to participate in the network communication and updated to the ticket id manager.

TID Based Routing:
In this section, the routing is planned for which TID updates the node's properties. The total number of routing paths are initialized. Then the route distance is calculated by the nodes coordinate position such as a,b. The routing path is selected under three conditions good, average, and poor. The good state determines all the node's properties are efficient, thus chooses an efficient available path with no traffic. If the condition is average, the node's properties are average; then, there is a possibility of high traffic, which means the route is busy then choose another available path. If the condition is poor, then the node properties are poor; wait until the node's status updates.

As mentioned above, the network model deployed, and TID protocol provides each node with a unique ticket-ID. Here on the nodes structure, M denotes the nodes, and T indicates the ticket-ID. The source node is M1, and the destination node is M6. For these two nodes, the provided tickets are T1 and T6, respectively. The proposed protocol uses the ticket-ID and updates the node's parameters to the ticket-ID manager. The ticket-ID manager chooses the effective shortest path from M1 to M27. There two-path chosen, such as   T1   T2   T3   T4   T5   T6   T7   T8   T9  T10   T11   T12   T13   T14  T15   T16   T17   T18   T19   T20   T21  T22   T23   T24   T25   T26   T27

This network is a dynamic one created using a Random way mobility modelin which the nodes are free to move anywhere. Here IEEE standard of 802.11 Mac protocol is taken as the link-layer protocol. The network traffic is generated using a multicast constant bit ratio. In this experiment, both 802.11b and IEEE 802.11e WLAN heterogeneous traffic is considered. The node mobility range is between 10-35/ms.The TCP or UDP network topology is used for establishing the data connection. The packet size is 2000 bytes, with the data rate at 24 Mbps. The other simulation parameters are described in the below

Simulation results
Several mechanisms are evolved in determining the efficiency of the routing mechanism in MANET. The proposed system efficiency is declared by a comparison work between the TABRP, OGFSO, and PDMR. The evaluation metrics taken for comparison are packet delivery ratio, average end-to-end delay, routing overhead, and average energy consumptions. The obtained observation is plotted in the graph for better decisions. Let's discuss each algorithm's performance according to the evaluation metric in detail.

Packet Delivery Ratio:
Packet Delivery Ration (PDR) is one of the vital evaluation metrics in determining the network performances. If PDR increases automatically, the network performances also increase. It states the total number of packets successfully transmitted to the destination. The ratio is calculated by the number of packages delivered in total to the total number of packages sent between the sender to receiver. It can be expressed as below; = ℎ ℎ * 100 But in TID-BRM it is designed without any link failure; at the same, the alternative paths are discovered only for calculating which one is the shortest path and in case of exception. The OGFSO clustering mechanism is discovered with cluster head and cluster members, but our ticketing system enhances with minimum time consumption in successfully delivering the packets. The ticket ID acknowledges the successful packet delivery, but it's not confirmed in OGFSO. In TABRP, there is no final decision regarding the sleeping or idle nodes happens if it joins the network. The proposed TID-BRM achieves with 20 nodes PDR is 25%, 40 nodes the PDR is 45%, on 60 nodes the PDR is 65%, on 80 nodes the PDR is 78%, and with 100 nodes the PDR is about 95%. On comparison, the proposed overall packet delivery ratio is 61.8 %, whereas with PDMR is 21.8%, OGFSO with 25.8%, and TABRP is 38.2%. The result shows that the proposed TID-BRM achieves the maximum number of successful packet transmission on all the stages.

Average End to End Delay:
In transmission, the packets are sent from source to destination. End-to-End delay refers to the total time spent on communication from source to destination. The RTT round trip time, which states the time to go and come back to the host. Minimum end-to-end delay results in reliable transmission with higher efficiency. It is calculated by the difference between the received time and sent time with the total number of packets sent. This evaluation metrics is essential to achieve network QoS (Quality of Services). It can be expressed as follows; The above figure 7 illustrates the average end-to-end delay achieved by proposed TID-BRM, PDMR, OGFSO, TABRP. The graphical representation classifies the obtained performances. The X-axis states the average end to end delay obtained by each algorithm, and Y-axis states the total number of nodes. At each stage, the number of nodes increases gradually with 20 nodes. The average end to end delay is measured in the aspect of seconds. The proposed TID-BRM has a 0.178-sec delay with 20 nodes, 1.25-sec delay with 40 nodes, 1.95-sec delay with 60 nodes, 4.46sec delay with 80 nodes, and 6.25-sec delay with 100 nodes. As mentioned in PDR, even though each mechanism has some drawbacks and achieves with minimum delay. But on the comparison, our proposed TID-BRM has an overall average end to end delay with 2.8 sec whereas PDRM has a 4.6-sec delay, OGFSO has a 5.1-sec delay, and TABRP has a 5.7-sec delay. These values and the graphical representation state on the comparison, the proposed TID-BRM has a very minimum delay than others.

Routing Overhead:
The Routing Overhead describes the searching of a broadcast link between the sender and receiver. In MANET, link breakage causes severe damages in the network performance. Routing overhead is an interruption that occurred on the selected path for packet transmission. The link faults or reroutes that leverage the network performance. The routing overhead is calculated by the total number of packets sent for maintenance and route discovery. It can be expressed as follows; This result is because compared to others, our proposed TID-BRM has a precise routing mechanism in which the TID manager controls the overall routing process. The TID manager not participating in the transmission; hence the energy level is high, and results with minimum routing overhead; this concept was not disclosed in other mechanisms. The proposed system achieved routing ahead is very low compared to other algorithms, as shown in the graph.

Average Energy Consumption:
In a network, energy consumption is the primary factor. The node's energy level determines the transmitting efficiency. The minimum energy is obtained by designing an energy-efficient protocol. In transmission, the energy consumption is identified through four terms: transmit, receive, idle, and sleep. It can be calculated by the total energy consumed with the number of nodes and initial energy. It can be expressed as follows;

Conclusion:
A new Ticket-ID Based Routing Management System (T-ID BRM) is proposed in this paper. In this work, the multipath routing protocol is enhanced with our TID protocol. The proposed system addressed the multipath routing protocol complexities and overhead issues. The ticket-ID mechanism overcomes these issues and balances the traffic effectively. The ticket-ID manager plays a vital role in the mechanisms, and overall performance occurs under its supervision. The TID examines the nodes factor, and based on the obtained value; the neighbor nodes are selected for transmission. Another component, route maintenance, delivers the optimal routing path, which is described in the algorithms. The performance of the proposed protocol is evaluated through comparison work. The comparison work is carried between TID-BRM with PDMR, OGFSO, TABRP. The evaluation metrics considered are packet delivery ratio, average end to end delay, routing overhead, and average energy consumption. The obtained performance values are graphically represented. From the result, it is proved that the proposed TD-BRM is far better than the other mechanisms.
In the future, this ticketing system can be enhanced in the aspect of security metrics.
