Performance Evaluation of Table Driven Multipath Routing Protocols in MANET under varying Nodes, Traffic load & Pause time

Abstract: Routing in ad hoc networks is somewhat more complex than routing in regular wired networks. Unreliable links and (possibly) rapid changes in topology calls for customized routing protocols. This essay aims to discuss two such protocols, namely MPOLSR and MDART The common belief is that the same is true for ad hoc networks, i.e., multi-path routing balances the load significantly better than single-path routing. Our Protocol, called MPOLSR & MDART is a multipath routing protocol for MANET. In addition route recovery & loop detection are implemented in MPOLSR in order to improve quality of service regarding OLSR.MP-OLSR is suitable for mobile, large & dense network with large traffic & could satisfy critical multimedia applications with high on time constraints. While MDART is an efficient protocol which gives improved performance in large networks. MDART is an enhancement of shortest path routing protocol known as Dynamic Address Routing (DART).MDART discovers and stores multiple paths to the destination in the routing table. In this paper, we have compare and analysis the performance of Table driven multipath routing protocols in MANET under different scenarios & metrics using NS-2.
