Delay and Reliability Aware Optimal Communication in Intelligent Vehicular Adhoc Network (VANETs)

In Vehicular Adhoc Network (VANETs) traffic congestion free effective path selection becomes a critical task which affects to achieve maximum performance is intelligent transportation system (ITS) based applications. Certain special characteristic in VANETs includes high speed, unpredictable mobility among the vehicles which increase the demand of providing effective vehicle traffic control. Additionally, process communication between the Road Side Units (RSUs) and vehicle is needed. For that purpose, in this article, Delay and Reliability Aware Optimal Communication (DROC) process is introduced which consists of intelligent network model with effective parameter-based path selection to achieve maximum performance n vehicle-based communication. At the initial stage, the effective network model is achieved using the On-Board Unit (OBU) and RSU construction, fitness function-based communication with Adhoc On-demand Multipath Distance Vector (AOMDV) routing protocol. Followed by that two operations are performed in proposed DROC process they are microcell and macrocell RSU construction and parameter-based analysis (distance and energy). Through this method optimal communication is attained in intelligent manner. The implementation of this model is done using the network simulation software and the parameters which are considered for the results analysis are packet delivery ratio, throughput, energy consumption, end to end delay and packet loss and as well it is compared with the recent researches like ISFF-VANET and ROOP-VANET.
