Comparative Analysis of GPSR and GPVR Protocol for Various Parameters in VANET with Power Control

Abstract

Vehicular Ad-Hoc Networks (VANETs) are deployed to make communication between vehicles possible using ad hoc wireless devices. Nowadays, these networks have become an emerging technology due to the variety of their applications in Intelligent Transportation Systems (ITS). By creating a vehicular network, each vehicle can exchange information to inform drivers in other vehicles about the current status of the traffic flow or the existence of a dangerous situation. They can also be used to improve traffic management conditions such as route optimization, flow congestion control and to provide on-board infotainment such as Internet access, the location of free parking places, video streaming sharing, etc. GPSR protocol utilized for wireless sensor networks in base paper. First of all various parameters must be take care for whom our research would revolve and then finding the demerit of existing protocol. By analyzing the problem of existed protocol a new protocol need to be designed. In our dissertation work GPVR (Greedy Perimeter Vector Routing) protocol is designed. After that various parameters like throughput, end to end delay, packet loss ratio and energy would be compared of both protocols that is existed one and proposed one. In our research work GPSR protocol is enhanced by using position vector calculation and simple redundancy elimination. After analyzing results of both protocols, finally we came to the conclusion that proposed protocol that is GPVR performs better. This research work carried out in NS2 software because it is peril and menacing free, In simulation various possibility can be made regarding smash of vehicles, in rural and urban area. So computer simulation is very crucial in VANET research. VANET Simulation extended into two parts that is traffic simulation and Network simulation
