On demand Multipath Routing Protocol for Ad hoc Networks

Abstract-Energy in mobile adhoc networks is of much important. Similarly shortest path from source to destination is also important for routing. To address these issues a routing protocol is proposed which gives an optimum between these issues. Power aware adhoc on-demand multipath distance vector (PAAOMDV) is proposed to overcome the issue of energy and shortest path in a single routing protocol. This protocol helps in updating the routing table with both the node route list and their corresponding energies. As this is a multipath protocol, it shifts the route without further overhead, delay and loss of packets. Simulation results shows that PAAOMDV performs well compared to ad-hoc on-demand multipath distance vector (AOMDV) routing protocol even after introducing energy related fields in PAAOMDV.
