Abstract

Routing protocols play an important role in mobile ad hoc networks (MANET) [1]. Sungle-Ju Lee and Mario Gerla proposed AODV-BR [2] to improve AODV [3], [4] by providing multiple alternate routes. However, the node which detected link failure maybe move to the position where no alternate routes can be used or nodes on the alternate paths have to transmit other data packets. Therefore, the effect of multiple alternate routes will be reduced. In this paper, we propose two hops backup routing scheme to provide more alternate routes with little setup overhead, resulting in better performance in high mobility and heavy traffic load environment.
