5G technology is essentially meant for offering superior user experience with higher consistency, maximized availability, enhanced capacity to support massive network, highly reliable, supportability towards ultra-low latency, along with higher rate of data transmission speed [1][2]. However, the importance of the 5G technology is not due to the above-mentioned characteristic but on its power to transform the world of communication system [3]. One of the direct influences of 5G is its potential support towards Internet-of-Things (IoT) and Internet-of-Vehicle (IoV) [4][5]. Usage of IoT enables the availability of a massive set of interconnected networks that not only assists in perspective of high-end communication but also assists in opening avenues of various analytical schemes to deal with big data [6][7]. Further IoV targets not only to make the transportation system intelligent but also to ensure higher ranking of user experience while it further pave the way to futuristic unmanned autonomous vehicle [8][9]. Apart from this, 5G also potentially supports the industry to leverage the principle of automation adhering to maximize the adoption of Industry 4.0 [10][11]. Owing to its superior data transmission rate and sustainable bandwidth, 5G network can assists in establishing far reaching connectivity which conventional connectivity cannot reach along with its significant technological revolution in augmented reality [12], virtual reality [13], 3D holograms [14], etc. 5G also improves upon the sector towards security [15] and health [16]. However, irrespective of above-mentioned beneficial features, 5G is also shrouded with various challenges [17]. The primary challenge in 5G network is associated with its hosting of multiple services with massive number of operating devices, technologies, and heterogeneous networks [18]. The biggest challenge resides in introducing standardization of large services to cater up dynamic requirement of users. Apart from this legislation of cyberlaw, rising concern of privacy and security, integrated upcoming application with sensing, navigation, communication, and massively connected infrastructure is yet a wide-open challenge in 5G technology [19][20]. All this above-stated challenges are required to be solved in order to for the 5G to be completely harness its potential towards various application.
Since the past half decade, there is an exploration about the potential of Artificial Intelligence and Machine Learning approach in leveraging 5G technology [21]. The significance of machine learning is towards its capability to use massive data subjected for computation analysis to yielding efficient decision based on input data [22]. When machine learning is used in networking than it assists the network engineer to generate intellectual analytics with better predictive capability towards understanding the flow of traffic which directly can control many performance metrics without any intervention of human [23]. From the perspective of 5G network, machine learning can potentially assist in performing proactive and predictive operation that maximizes the value of using 5G networks and its supported services and applications [24]. Apart from this, it also assists in automating various business process with enhancement towards business enterprises thereby understanding the need of customers. It is to be noted that 5G offers an exponential connectivity to a large number of heterogeneous devices that runs over underlying complex forms of network and computing architectures [25]. This eventually constructs a high-end capability towards analyzing big and complex form of data in order to curve it for better value-added services or products. However, the prime focus on integrating machine learning approach is to optimize the network performance along with minimization of the capital expenditures. However, this is not so simpler task to implement such integration.
On the contrary, the data generated by the machine learning has witnessed an increased utility towards curving a predictive tool which can intrude the privacy information of the user [26]. Apart from the perspective of security challenges, the bias can be quite amplified by machine learning giving rise to higher iterative and complex process to check and minimize it. Apart from this, adoption of either supervised, unsupervised, or even hybrid form of machine learning approaches is always accompanied by both beneficial and limiting characteristic [27]. At the same time, deep learning has penetrated more in improving predictability performance in 5G. However, there is a potential difference between adoption of either of this technique. Deep learning approach does not have any dependency towards network data structure while machine learning does. Apart from this, owing to inclusion of massive number of protocols and services in 5G, there is possible occurrence of errors. Such errors can be autonomously checked by deep learning without any intervention of humans which is not the case with machine learning. However, a deeper insight towards trends of Artificial intelligence shows that machine learning is more considered in investigating 5G network as it can function using low resources which is not the case with deep learning. Apart from this, execution time of machine learning is significantly lower compared to deep learning. Therefore, the proposed scheme implements a novel scheme of machine learning approach which can optimize the performance of traffic management in 5G. The contribution of proposed scheme are as follows:
-
Proposed scheme deploys a large and novel scenario of 5G service deployment meant for facilitating navigational services to mobile user via their user handheld device.
-
An enhanced Long Short-Term Memory is used for constructing a predictive model towards furnishing distributed information of optimized routes.
-
The study outcome is benchmarked with existing learning scheme on various parameters to show its effectiveness.
