Wireless mesh network (WMN) are reliable, multiradio, multihop next generation wireless networks which are capable of delivering high throughput demanded applications through the integration of various technologies. WMN delivers efficient services for a large variety of applications on local, personnel and campus environments. Multicasting is one of the major communication technologies primarily designed for bandwidth conservation and an efficient way of transferring data to a group of receivers in wireless mesh networks. Despite of the vantages of the WMN there can be several issues that affect the entire and the false accusations raised by the nodes. A mere way to identify the malicious node is to collect the information from nodes in the entire network. Nevertheless, in the above said approach, i the valid accusations made by legitimate nodes from false accusations made by malicious nodes. Also, the amount of traffic needed in order to exchange peculiar information on attackers and the necessary time to information increases as the network size becomes more prominent. In this paper, we propose a certificate revocation mechanism which is able to revoke the certification of attackers in a limited period of time with a small amount of controlling traffic. By the clustering of nodes and introduction of multi proposed scheme can mitigate the improper certificate revocation due to false accusations by malicious use
