AODV-BR: Backup Routing in Ad Hoc Networks

Nodes in mobile ad hoc networks communicate with one another via packet radios on wireless multi-hop links. Because of node mobility and power limitations, the network topology changes frequently. Routing protocols therefore play an important role in mobile multi-hop network communications. 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, the authors propose a scheme to improve existing on-demand routing protocols by creating a mesh and providing multiple alternate routes.
