AMAC scheduling: To optimize QOS for DSRC
Vehicle to Vehicle communication is comes under ehicular ad hoc network (VANET) VANET uses the concept of mobile ad hoc network. VANET gives flexibility to communicate between high speeds vehicles and create a network. VANET classification is done in three different category such as Vehicle to Infrastructure (V2I) Vehicle to Vehicle (V2V) and Hybrid network which is a combination of V2V and V2I network. VANET can be very effective in road safety communication, at the time of network congestion or entertainment purpose. But as services is increases QoS providing to the end user is a challenging task for service provider because of wireless medium and nature of node (vehicle is mobile with very high speed. The existing protocol proposed till today's date does not consider network initialization advertisement, periodic beaconing factor which are necessary to provide effective V2V. Due to which the broadcasted packets are neither acknowledged nor it is retransmitted which in turn increases the frame loss due to channel error. To cater this in work the author propose an Adaptive Medium Access Control (AMAC) Scheduler for prioritized multi channel Dedicated Short Range Communication (DSRC) based V2V communication in IEEE 802.11pMAC protocol. The simulation is conducted for collision, packet transmission and throughput efficiency for varied vehicle. The experimental result shows the proposed AMAC scheduler, performs better than existing Non Cooperative Cognitive Multiple Access (NCCMA) in term of collision, successful packet transmission and throughput efficiency for varied no. of vehicle and thus helps improving QoS for DSRC based V2V communication for different application like safety and non safety related application.
