Performance Comparison of Routing Protocols

Abstract: A mobile ad hoc network (MANET) is a collection of wireless mobile nodes dynamically forming a network topology without the use of any existing network infrastructure or centralized administration. MANET is a self configuring network and the topology of the network keeps on changing as the nodes move randomly and organize themselves in an arbitrarily manner. Mobile nodes communicate with each other using multihop wireless links. Each node in the network also acts as a router, forwarding data packets for other nodes. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. Due to higher mobility in nodes and dynamic infrastructure of MANETs, Routing is important issue in ad hoc networks. ‗In this paper three routing protocols AODV (Ad- Hoc on-Demand Distance Vector), DSDV (Destination Sequenced Distance-Vector) and DSR (Dynamic Source Routing) are compared‘. The metrics used for performance analysis are Packet Delivery Ratio, Average end-to-end Delay & Number of Packets Dropped.
