NSSC: Novel Segment Based Safety Message Broadcasting in Cluster-Based Vehicular Sensor Network

摘要: Extensive research attention has been devoted to the Vehicular Sensor Network (VSN) owing its great potential in environment monitoring. Still, it is difficult diminish broadcast storm and data collisions vehicular senor environment. Due improper broadcasting of safety message transmission packet at same time from multiple vehicles leads collision. Our key intention overwhelm these shortcomings VSN. Hence, we propose Novel Segment based Safety Cluster (NSSC) NSSC mainly concentrated three successive processes that are Formation, Collision Avoidance Message Broadcasting. formation performed originally sustain stable Here, Variant Clustering (VbC) Scheme proposed elect Head (CH) form clusters. CH selected using Chaotic Crow Search (CCS) algorithm. In accord mitigate collision during between Member, Adaptive Carrier Sense Multiple Access/Collision (Ada-CSMA/CA) protocol. adopts Forwarder Selection (SFS) scheme which selects optimal forwarder Fuzzy-Vikor method. this, concerning reduces storm. regard validate NSSC, have conducted simulations on Omnet++ SUMO simulator Veins framework. The acquired results auspicious terms succeeding metrics reachability, average number collision, duplicate packets, latency, delivery ration throughput.
