Time based clustering technique for routing in wireless sensor networks

A Wireless sensor network(WSN) is a collection of tiny sensor nodes which are randomly deployed in distributed environment. Because of the limited capabilities, especially the energy reserve and processing ability of the sensor node, 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 wireless sensor networks based on the node residual energy compared to the network one and allowing a better partitioning the network area. The simulation results show that this algorithm allows network stability extension compared to the most known clustering algorithm.
