Abstract :
Nodes in mobile ad hoc networks communicate with one another via packet radios on wireless multihop links. Because of node mobility and power limitations, the network topology changes frequently. Routing protocols therefore play an important role in mobile multihop network communications. This network is intended for situations when it is not economically practical or physically possible to deploy the necessary infrastructure, for example in temporary or remote locations such as rescue operations or military applications [1]. A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. In this paper, I propose a scheme to improve existing on-demand routing protocols by creating a mesh and providing multiple alternate routes. My algorithm establishes the mesh and multipaths without transmitting any extra control message. I apply my scheme to the Ad-hoc On-Demand Distance Vector (AODV) protocol and evaluate the performance improvements by simulation.
