Abstract
Ad hoc networks are characterized by multi-hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. In this paper we compare the performance of three on-demand routing Protocols for mobile Ad-hoc network (MANET) networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV) and Temporarily Ordered Routing Algorithm (TORA) in by varying the size of the networks. The performance metrics selected to make the performance differences are Total Traffic Received, Traffic Load, Throughput, Number of Hops per Route and Route Discovery Time. AODV shows a Considerable better performance over the others for any number of nodes. TORA and DSR show moderate performance for minimum number of nodes, where in the case of large networks, DSR shows some performance rather than TORA.
