Peer to Peer Network for mobile is not centralized but self managing network with no specific topology. Topology of the Peer to Peer Network for mobile is change with change in time. In Mobile Peer to peer network various group communication protocols exists for multiparty conferencing. A mobile Peer to Peer network consisted of many security risks such as Decentralization of data storage, unusable connections, unauthorized access of data storage, provide connection to temporary IP address, Possess significant or total autonomy from central servers. Both file sharing and instant messaging are unsecure due to unavailability of encryption in both ends sender as well as receiver site in different peer to peer mobile network protocols. In this research our goal is to compare different group communication protocols in peer to peer mobile networks. and to suggest an efficient and secure protocol for group communication over peer to peer mobile network.
