Speed and Overhead Based Resource Allocation and Its Performance Analysis in V2X Communications

In Vehicular Adhoc Network (VANETs), the communication is performed among vehicles and with the infrastructure and that helps to improve the vehicles safety. The exchange of data in VANETs is complicated because the vehicles travel in high speed with frequently changing topology. However, this limitation in vehicular communication brings a need to provide effective resource allocation. With the intension of that in this article the Speed and Overhead based Resource Allocation Process (SORAP) is initiated. The core idea of this proposed model is that it performs improved resource allocation. At the initial stage the network is developed into certain clusters and the communication is separated for one hop and two communications. According the Time division strategy the transmission carried out and that’s leads to attain stable communication among the vehicles. The implementation of the proposed SORAP is experimented in NS2 and to know the superiority of SORAP its results are compared with the recent baseline methods like ORPSO and PTAMT. From the results outcome it is proven that SORAP achieved 5% high delivery ratio, 65 ms lower delay, 80 packets lower packets loss and 180 packets lower routing overhead.
