Mobile Ad hoc NETworks (MANETs) is a network composed of many nodes connected via wireless links. The topology is dynamic in nature. Nodes of MANET are grouped into clusters to restrict the spreading of information between the set of nodes. Each node in a cluster is supervised by a leader node known as Cluster Head (CH). The cluster head is to maintain the affiliated node list and also to communicate with the other clusters. Maintaining cluster head has some advantages like it allows fast communication, topology management and better routing.
