A Distributed Energy Balance Clustering Protocol for Heterogeneous Wireless Sensor Networks

Sensor networks have a wide range of potential, practical and useful applications. However, there are issues that need to be addressed for efficient operation of sensor network systems in real applications. To extend the lifetime of a sensor network, clustering algorithm is a kind of key technique used to reduce energy consumption, which can increase network scalability and lifetime. In this paper, we proposed a distributed energy balance clustering (DEBC) protocol for heterogeneous network. Cluster heads are selected by a probability depending on the ratio between remaining energy of node and the average energy of network. The high initial and remaining energy nodes have more chances to be the cluster heads than the low energy nodes. Simulation result shows that our protocol provides longer lifetime than the existing clustering protocol and uses the best of energy in heterogeneous network.
