Abstract

Based on the analysis of the node selfishness and the drawback of min-hop selection method as the unique routing selection criteria in ad hoc networks, a non-intrusive multi-metric ad hoc routing protocol-NIMR is presented. By computing and storing the node fame, NIMR greatly attenuates the influence of node selfishness; By crossing-design between MAC layer and network layer, we employ a non-intrusive real-time available bandwidth measurement scheme to solve the congestion problem. Finally, we propose a new metric as the routing selection criteria, which combines fame, available bandwidth and minimum hops by weight. Simulation results show, Compared with DSR, fairness between nodes is improved and congestion control and load balance is implemented using NIMR without additionally increasing the network load. At the same time average life-span and end-to-end throughput is increased, average end-to-end delay is decreased using NIMR.
