Energy balanced clustering algorithm for routing in heterogeneous wireless sensor networks

Because of sensor nodes have limited capabilities, especially the energy reserve and processing ability, routing protocols in wireless sensor networks are a crucial challenge. These routing protocols should be simple, energy-efficient, and robust to deal with a very large number of nodes. They should also be self-configurable to node failures and changes of the network topology dynamically. The most proposed routing techniques organize the network in clusters where the sensing area is divided into many sub-areas. This paper presents a new algorithm for cluster forming in heterogenous wireless sensor networks based on the node residual energy compared to the network one. The simulation results show that this algorithm allows network stability extension compared to the most known clustering algorithm.
