Abstract: Wireless Ad hoc network is a set of wireless devices which move randomly and communicate with other node via radio signal. Ad-hoc networks may be logically represented as a set of clusters by grouping together nodes on the basis of different criteria such as 1-hop and k-hop that are in close boundary with one another. Clusters are formed by diffusing node identities along the wireless links. Different heuristics employ different policies to elect cluster heads. Several of these policies are biased in favour of some nodes. As a result, these nodes should greater responsibility and may deplete their energy faster, causing them to drop out of the network. Therefore, there is a need for load-balancing among cluster-heads to allow all nodes the opportunity to serve as a cluster-head. In this paper, different cluster head election mechanism are discussed in the one hop clustering approach.
