Mobile Ad-hoc NETwork (MANET) is a group of wireless nodes join together to form a network without a defined architecture. It is formed dynamically as the nodes are mobile in nature. This characteristic of MANET could lead to insecure information exchange. Applications in Mobile Ad-hoc NETworks (MANET) such as military or public emergency network require secure multicast communication. Multicasting supports group oriented communication. A cluster based system provides easy key management within a cluster or a group. In such an interaction system, a new member can join and a current member can leave at any time. This overcomes the issues of energy consumption, end to end delay, unreliability with high packet drop rate and low key delivery ratio.
