In location-aided routing of Mobile Ad hoc NETworks (MANET), nodes mobility and the inaccuracy of location information may result in constant flooding, which will reduce the network performance. In this paper, a Distance-Based Location-Aided Routing (DBLAR) for MANET has been proposed. By tracing the location information of destination nodes and referring to distance change between nodes to adjust route discovery dynamically, the proposed routing algorithm can avoid flooding in the whole networks. Besides, Distance Update Threshold (DUT) is set up to reach the balance between real-time ability and update overhead of location information of nodes, meanwhile, the detection of relative distance vector can achieve the goal of adjusting forwarding condition. Simulation results reveal that DBLAR performs better than LAR1 in terms of packet successful delivery ratio, average end-to-end delay and routing-load, and the set of DUT and relative distance vector has a significant impact on this algorithm.
