HWMP provides two routing modes,proactive mode of tree-based routing protocol and on-demand mode of AODV routing protocol.There are a lot of problems in this protocol,such as low expansibility,efficiency and the root is the weak point.When the traffic is heavy,the collision and loss of data packets will increase.This paper proposed an improved algorithm based on hybrid wireless Mesh protocol to solve above problems.In the Mesh network,the source node could calculate the best-metric route to any destination quickly when used the proposed algorithm.The improved protocol combined proactive mode with on-demand mode to apply to all transmission environment.The simulation results reveal that the improved protocol gets better performance on packet delivery rate,average end-to-end delay and throughput.
