Wireless Mesh Network is designed static or limited mobility environment .In multicast routing for wireless mesh networks has focused on metrics that estimate link quality to maximize throughput andtoprovide secure communication.Nodes must collaborate in order to compute the path metric and forward data.Node identify the novel attacks against high-throughput multicast protocols in wireless mesh network..The attacks exploit the local estimation and global aggregation of the metric to allow attackers to attract a large amount of traffic These attacks are very effective b a s e d on high throughput metrics.The aggressive path selection is a double-edged sword: It is maximizes throughput, it also increases attack effectiveness.so Rate guard mechanism will be used.Rate guard mechanism means combines Measurement-based detection and accusation-based reaction techniques.The attacks and the defense using ODMRP, a representative multicast protocol for wireless mesh networks, and SPP, an adaptation of the well-known ETX unicast metric to the multicast setting.
