Abstract: This paper improves the AODV protocol used in the wireless Ad hoc network, realizes a new hybrid routing architecture by combining active and passive protocol, increases range limitation mechanism and compromise of distance and energy, the improved HR-AODV protocol has a better performance in Wireless Mesh Network(WMN), and it is more suitable for upper level applications in network layer. Simulation results using NS2 show that the HR-AODV protocol achieves a larger improvement in the network latency, packet loss rate, thought and so on, it has stronger robustness and fault tolerance.
