Theoretical and Simulation Study of Wireless Ad-Hoc Network Routing Protocols and Their Performance Evaluation

Abstract

In the recent years the number of vehicles on road increases at high speed. A lot of road accidents and traffic congestion emerges. So to control it vehicular ad-hoc network came in picture. In the last few years many protocols were proposed to route the packets efficiently and correctly. But no one was capable of routing the packets in case of cross links. So, a protocol named GEOCROSS was proposed. The introduction of MANETs, VANETs, their routing protocols, protocol structure of VANET, how broadcasting takes place in VANET, how information is disseminated in VANET and VANET communication & routing protocols like vehicular collision warning communication (VCWC), vehicle heading based routing protocol (VHRP) and GEOCROSS routing protocol will discussed in this paper.
