| Abstract: | Unicast routing protocols proposed for Mobile Ad hoc Networks have certain limitations. These protocols try to discover the route on-demand by flooding route request messages, which results in increased end-to-end latency and also consumes considerable amount of network bandwidth. These limitations make protocols not suitable for real-time multimedia communication. This paper proposes a Mobile Agents aided Routing Protocol (MARP), for routing in Mobile Ad Hoc Networks. Mobile agents collect network connectivity information and disperse this information across the network. This network connectivity information forms the "ready routes" that can be used during route discovery and route maintenance phases. Thus, MARP avoids the expensive route discovery/maintenance process. MARP uses Ad Hoc On-demand Distance Vector routing (AODV) as the underlying protocol. MARP and AODV protocols are compared through extensive simulations. Network throughput, end-to-end delay and routing overhead are the performance parameters considered. Results show that the ready routes provided by MARP, when compared to traditional on-demand routing protocols such as AODV, results in substantial reduction in end-to-end delay and improvement in network throughput. |
