In this paper, the authors propose a new hybrid routing protocol for MANET called Location Aided Hybrid Routing Protocol for MANET (LAHRP). The proposed routing algorithm not only aims to optimize bandwidth usage of MANETs by reducing the routing overload but also extend battery life of the mobile devices by reducing the required number of operations for route determination. Although in the LAHRP, some features of both table-driven and on-demand algorithms were used to achieve these goals at some stages, LAHRP algorithm is a completely different approach in terms of position information usage and GPS. Simulation results are used to draw conclusions regarding to the proposed routing algorithm and compared it with the standard DSR protocol.
