This paper contributes to the issue of location-aided routing in ad-hoc wireless networks. It focuses on the location-aided routing (LAR) protocol and its way of building the forwarding zone. A modified-LAR algorithm is proposed and three variants of it are examined. All of them are based on the idea of enlarging the request zone, in case of failure of the route discovery phase, instead of restoring to flooding. Simulation results show that the proposed algorithm leads to an improvement in the control overhead.
