Abstract: To solve the problem of network congestion caused by broadcasting PＲEQ ( Path Ｒequest) messages
and proxy update messages across the hybrid wireless mesh network in the inter-domain mobility management
scheme of HWMP ( Hybrid Wireless Mesh Protocol) protocol，a new routing update algorithm for new nodes in
proactive routing mode of HWMP protocol is proposed，which restricts sending PＲEQ messages to some extent，
improves the mechanism of inter-domain mobility management of HWMP protocol and reduces the number of
routing update packets in the whole network． It reduces the end-to-end delay of the network． The simulation
results show that the AHWMP ( Advanced Hybrid Wireless Mesh Protocol) scheme has better performance than
that of HWMP protocol in terms of average network throughput and average end-to-end delay．
