Comparative performance analysis of GZRP, AOMDV and DSR in MANETs

A MANET is an autonomous group of mobile users that communicate over reasonably slow wireless links. The network topology may vary rapidly and unpredictably over time, because the nodes are mobile. Routing is a significant issue and challenge in ad hoc networks and many routing protocols have been proposed like OLSR, AODV, AOMDV, DSDV, DSR, ZRP, GZRP and TORA, LAR so far to improve the routing performance and reliability. Genetic Zone Routing Protocol (GZRP) is a new multipath routing protocol for MANETs. It is an extension of ZRP which is a most promising, widely accepted and well proved hybrid routing protocol in Mobile Ad-hoc Networks (MANETs) for its performance when compared with table-driven and on demand protocols. AOMDV is another multipath routing protocol, which is extended from AODV, a source routing protocol. This paper aims to analyze the performances of AOMDV, GZRP and DSR routing protocols with respect to packet delivery ratio, end to end delay and control overhead.
