V2X Communication based Dynamic Topology Control in VANETs

With the development of Vehicle-to-everything (V2X) communication systems, the need to increase efficiency of the VANET or vehicular ad-hoc networks has risen. One of the methods of doing so is to improve the topology control, especially the dynamic topology. In this paper, we propose a V2X communication based mixed approach for dynamic topology control. The mixed approach consists of both Proximity Graph and Map-matching algorithms, each of them get activates depending upon the context and traffic scenarios. We compared the proposed approach with various existing topology control systems. The proposed mixed approach is simulated using various scenarios in MATLAB and SIMULINK. Further, we have simulated a real-world scenario using road lanes, traffic signals, and actual vehicles on SIMULINK using the VANET toolbox. In the simulation, we have used various parameters to analyze the performance measures such as energy consumption, throughput, network life time, etc. The results analysis shows the effectiveness of the proposed mixed approach for dynamic topology control in the VANET.
