The use of mm Wave or millimeter wave bands for systems based on mobile and wireless communication’s next generation is a promising alternate that has the capability for supporting continuous rates of data over tens of Gigabits per second or Gbps. Although the advantages are clear of using a large available spectrum, there are some challenges which are related to the characteristics of propagation at higher frequency bands which are needed to be dealt. In the existing system, an adaptive transmission that can reduce the probability of outage of secrecy capacity primarily when the mean signal to noise ratio of the eavesdropper is comparatively lower than the legitimate receiver’s mean signal to noise ratio. As more number of devices are connected to the network, security threats are also becoming a real concern. For ensuring the normal operation of smart city, monitoring of abnormal behaviors becomes essential. A smart city requires a guarantee mechanism which is reliable for guaranteeing the QoS. The network’s QoS or quality of service can be affected by various abnormalities in the network like abnormal flow, link fault and DDoS attack etc. which causes packet loss and also interruption of service. Also as more number of IoT devices are connected to the network, security threats are the main issue as more personal information becomes vulnerable.
In the proposed system, Design of Resilient or Spatial Correlation is evaluated, this kind of Spatial Correlation enable the physical later to do the iterative search for N number of times until the communication is established without any blockage of objects. To reduce the disconnection of data transfer due to line of sight issues, an adaptive Resilient Correlation scheme is newly proposed here.
