Performance Evaluation of AODV and AOMDV Routing Protocols in MANET
Main Article Content
Abstract
Mobile Ad Hoc Network is a collection of autonomous mobile nodes which communicate through wireless medium with
each other. In MANET the mobile nodes are self configuring and self organizing in nature. As MANET is an infrastructure less multi
hop wireless network without the aid of any centralized administration, plays an important role in military and civilian applications. In
MANET each node works as a host as well as a router to forward the packets from source to destination. Routing in MANET is very
complex task as the network topology changes continually as nodes are mobile. Reactive routing protocols for ad hoc networks
discover and maintain only the needed routes to reduce routing overhead. This paper evaluates the performance of two on-demand
routing protocols - Ad hoc On-demand Distance Vector (AODV) which is unipath and multipath version of AODV called Ad hoc Ondemand
Multi-path Distance Vector (AOMDV) routing protocols. AOMDV discovers multiple paths in a single route discovery.
Simulation is done in Network Simulator tool NS-2 for various performance metrics.
