An Efficient Dynamic Call Admission Control for 4G and 5G Networks

The goal for improved wireless communication between interconnected objects in a network has been long anticipated. The present Long Term Evolution (LTE) fourth-generation (4G) network does not allow the variety of services for the future need, as the fifth-generation (5G) network is faster, efficient, reliable, and more flexible. The 5G network and call admission control (CAC) are best certainty that defines the elementary principles of the smart cities of the upcoming 5G network technology. It is predicted that substantial CAC in the smart cites environment where millions of wireless devices are connected, communication will be granted based on latency, speed, and cost. Furthermore, the present CAC algorithm suffers from performance deteriorates under the 4G network because of the adaptive threshold value used to determine the strength of the network. In this paper, a novel CAC algorithm that uses dynamic threshold value for smart cities in the 5G network to address performance deterioration is proposed. Simulation is used to evaluate the efficacy of the proposed algorithm, and results show that it significantly performs better than do other algorithm based on the metrics measured.
