IGMP(Internet Group Management Protocol) is an integral part of IP multicast in wired networks. When it is used over wireless links, the amount of overhead increases significantly due to joint operation and the polling of mobile users by routers. And IGMP Joint is also having security threats such as local subnet attacks, subnet attack. Therefore it is inefficient and unsecured to implement IGMP Joint directly into wireless domain. The new method that we adopt should consider few facts, they are: Already the network is flooded with enough rate of control packets; Solution should maintain the multicast model as much as possible; Solution should minimize the introduction of using new functions. The proposed Secured Wireless Group Management Protocol(S-WMGMP) acts based on a alive-time-interval mechanism for join operation, considering the number of subscribers are sparse in the domain. Basic working prototype has been simulated and the results are good enough to go
