Traffic and Speed Analysis with Effective Topology Selection Using a Cross Layer Approach for Vehicular Adhoc Networks (VANETs)

A Vehicular Ad-hoc Network (VANET) is a trending high speed communication technology where the network consists of certain elements such as vehicles, roadside units (RSUs), On Board Unit (OBU) and others for the effective implementation of VANETs systems. Due to these special functionalities like high speed and random unpredictable mobility, during data transmission traffic congestion is highly increased that leads to increase the energy utility, delay and overhead at the time of multi-hop communication in vehicular environments. To overcome such flaws in this article Traffic and Speed analysis with effective topology selection is performed and as well which opens a way for a cross layer approach (TSAEC) between the physical layer and the data link layer in VANETs where it performed major operations like traffic signal analysis, vehicle speed analysis with intellectual topology building among the vehicles. Through this process the network traffic is effectually monitored and the high speed vehicles are handled in proper way that leads to increase the quality of the multi-hop communication among the vehicles. The implementation of the TSAEC-VANETs are carried out in OMNET++ where the parameters which are taken to analysis the network performance are message coverage capability, saved rebroadcast, average dissemination delay and average communication probability and as well it is compared with the earlier approaches like ICFD-VANETs and RDCI-VANETs. The performance of the proposed TSAEC-VANETs is high in term of communication reliability and throughput during data transmission in the communication channel.
