Mobility Assisted Routing in Mobile Ad Hoc Networks

This paper presents an algorithm to include mobility in a routing protocol to reduce packet losses in mobile ad hoc networks (MANETs). The algorithm is applicable to any on-demand routing protocol. If the degree of mobility of any node in any route increases, the route life time decreases. That causes frequent link failures, and results more packet loss and low throughput. Packet loss requires packet retransmissions, which further overload the network and can cause additional latency and packet loss. The proposed algorithm estimates the number of packets that can traverse through the route before it breaks be-cause of mobility. This algorithm increases network throughput and packet delivery ratio. The algorithm is implemented in dynamic source routing (DSR) protocol, and simulated in Network Simulator-2. The simulation results show that the packet delivery ratio of DSR with the algorithm can improve up to forty six percent over DSR in mobile ad hoc networks.
