对于无线Mesh网络中的MGMP路由协议,在信道切换过程中,Mesh节点数据报文可能会因找不到路由或数据拥塞而导致数据丢失。为了解决MGMP路由协议在路由策略和数据拥塞方面存在的问题和不足,提出一种MGMP路由协议报文缓存机制。详细论述了MGMP路由缓存机制思想及其具体实现过程。同时,对这种带缓存的MGMP路由机制进行了NS-2仿真测试和性能分析。实验结果表明:这种支持报文缓存的MGMP路由协议,能够更好地适应信道动态调整,从而提高了Mesh网络的整体性能。

During channel switching, data packets of Mesh node may be lost because of no route for MGMP muting protocol of wireless Mesh networks. In order to solve the shortcomings of routing strategy in terms of data packets lost and blocked, this paper mainly introduces MGMP (multi-gateway multi-path) routing mechanism which supports dynamic channel adjustment under multi-gateway and multi-radio. It states the ideas of MGMP routing mechanism and its procession to be realized. Performance evaluation of MGMP is done by NS-2.The simulation results show that the MGMP routing protocol based on the channel switch with multi-radio improves the Mesh total performance.
