The essential requirement in MANET is now group communication or multicasting since it is used in applications such as network news dissemination, collaborative computing, disaster relief operation, sensor network, military services. In this type of application reliability plays an important role. Designing a reliable multicast protocol in MANET is challenging task due to the dynamic topology, limited bandwidth, constraints of node capability, and frequent disconnections in MANET. In this paper, we propose a scheme called Congestion Control Anonymous Gossip(CCAG) to improve the reliable packet delivery of multicast routing protocols and decrease the variation in the number of packets received by the different nodes. It also consider the issues of reliability, low end to end delay, control overhead and packet delivery in mobile ad-hoc networks. The propose scheme works in two phases. In the first phase any suitable protocol is used to multicast the message to the group, while in second phase, the gossip protocol tries to recover lost messages.
