PERFORMANCE ANALYSIS OF ROUTING PROTOCOL IN MOBILE AD-HOC NETWORKS

Abstract

Routing in a mobile ad hoc network (MANET) is a difficult task due to the constantly changing network topology and the absence of a fixed infrastructure. In such a scenario, mobile hosts can act as both hosts and routers, forwarding packets for other mobile nodes in the network. Routing protocols used in MANETs must be able to adapt to frequent changes in topology, while minimizing the impact on wireless resources. The AODV, DSR, ZRP and DYMO protocol are specifically designed for mobile nodes in wireless multihop ad hoc networks. It is capable of adapting to the changing network topology and determining unicast routes between nodes within the network. This paper presents a comparative analysis of commonly used routing protocols in terms of key performance metrics, including Broadcast sent packets, CTS packets sent, Packet drops due to re-transmission,RTS re-transmission the timeout , Unicast packet received ,RTS packets sent,Packet due to ACK timeout, ACK packet sent, Unicast sent packet and Broadcast Packet Received. The study's findings demonstrate that the routing protocols' performance is influenced by the network's size, node density, and mobility patterns. These routing protocols showing the simulation performance using random waypoint model on qualnet simulator.
