Clustering is an efficient technique that is widely adopted in wireless sensor networks. It divides network into clusters and let cluster heads be responsible for forwarding aggregated data to the sink. With energy efficiency in account, the conflict between an individual node and the entire network remains to be solved. In this paper, the authors propose a Density-based Energy-efficient Game-theoretic Routing Algorithm (DEGRA). As a clustering algorithm, DEGRA adopts game theory and set a utility function based on the nodes' density, residual energy and average energy consumption of its neighboring nodes. Cluster heads are iteratively selected.
