Abstract

A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any preexisting
infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing algorithms
that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and several of
them have been extensively simulated or implemented as well. 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 proactive multipath routing protocols for MANET under different scenarios & metrics using NS-2.
