In wireless sensor networks, clustering divides network into clusters and makes Cluster Heads (CHs) responsible for data aggregation. CHs play a significant role in such topology and focus should be fixed on the CH selection. Due to the constraints on available resources, however, a sensor node is likely to be selfish and refuse to serve as a CH. Based on game theory, this paper models the problem and discusses the condition of nash equilibrium. Moreover, in case of disconnection between a CH and the sink, data replication is adopted.
