Abstract: The field of Mobile AdHoc Networks (MANETs) has gained an important part of the interest of researchers and has become very popular in last few years. MANETs can operate without fixed infrastructure and can survive rapid changes in the network topology. In MANETs, there are frequently disconnected routes consisting of multi-hop from a source to a destination because of the dynamic nature such as the topology change caused by node�s mobility. To overcome this situation, this study proposes a Multi Ant based Routing Protocol (MARP) for mobile AdHoc networks, which combines the on-demand routing capability of AdHoc On-Demand Distance Vector (AODV) routing protocol with a ant colony optimization mechanism using ant like mobile agents. AODV requires the actual communication to be delayed until the route is determined. This may not be suitable for real time data and multimedia communication applications. The Multi Ant based Routing Protocol (MARP) provides high connectivity, reducing the amount of route discoveries before starting new connections. This eliminates the delay before starting actual communication for most new connections making a multi ant based routing protocol ideal for real time communication in highly dynamic networks such as MANETs. We study the performance of this ant protocol for dynamic network topologies. We also compare, the performance of this multi ant based routing protocol with well known existing hybrid routing protocols ZRP and ARA, for AdHoc networks. Simulation results show that the new multi ant routing protocol proposed in this study is able to achieve reduced end-to-end delay as compared to existing hybrid routing protocol ZRP and ARA. In addition, this new multi ant routing protocol also provides significantly better packet delivery ratio, route discovery frequency and multimedia communication than ARA and ZRP for high and low mobility.
