In order to improve routing stability of Wireless Mesh Network (WMN),a novel Predictive and Fairness-aware Routing Protocol algorithm (PFRP) based on DSR was proposed. PFRP exploited network state information in MAC layer and passed it to the DSR routing agent,so that DSR agent chose the best route with less congestion and delay towards the final destination. Moreover,a new metric Degree of Congestion Control contrary to the concept of degree of congestion was proposed to denote the state of congestion control for transmission in the network node,which combined the available link bandwidth and the queue load capacity of node acquired by statistic and estimation methods. Simulation results show the better performance,such as fairness and load balancing of network flows,than that in DSR including delay and throughput is achieved with PFRP in WMN.
