Problem statement: One of the major issues in current reactive routing protocols for Mobile Ad Hoc Networks (MANETs) is the high bandwidth and power consumptions during the routing process. In this study, we proposed and evaluated the performance of an efficient Location-Based Power Conservation (LBPC) scheme for MANETs. Approach: In this scheme, the transmitting node utilized the location-information of the first-hop neighbors to adjust its radio transmission range according to one of the following criteria: Farthest first-hop neighbor, average distance of the first-hop neighbors and a random distance between the nearest and the farthest first-hop neighbors. Results: A number of simulation were carried-out to evaluate the power conservation ratio that can be achieved for two route discovery algorithms, namely, pure flooding and Location-Aided Routing Scheme 1 (LAR-1) algorithms. Conclusion: The simulation results demonstrated that the scheme can provide power conservation ratios between 10-50% without adding any extra overheads or complexity to the routing algorithm.
