摘要: 针对HWMP( Hybrid Wireless Mesh Protocol) 协议域间移动性管理方案中全网广播PREQ( Path Request) 消
息和代理更新消息造成网络拥塞的问题,提出HWMP 协议主动路由模式下新增节点的路由更新算法。对于
PREQ 消息的发送做出一定限制,改进了HWMP 协议域间节点移动性管理机制,减少了全网路由更新数据包的
数量,降低了网络的端到端时延。仿真结果表明,与HWMP 协议中的方案相比,AHWMP( Advanced Hybrid
Wireless Mesh Protocol) 方案在网络平均吞吐量、网络平均端到端时延等方面具有更好的效果。

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.
