MANET is an infrastructure-less network made up of distributed nodes. It is a self-organized, spontaneous and dynamic network. In mobile ad hoc network, due to temporary cooperation among nodes and lack of enough knowledge between each node in advance, it is difficult to establish trust. So, in MANET nodes are divided into number of clusters for establishing temporary network in order to perform certain actions more easily. In cluster based model, each cluster consists of one special node called Cluster-Head (CH). It maintains the communication among all the other nodes of its own cluster. It also communicates with other adjacent CHs through the gateway nodes.
