Improving the Energy Efficiency of a Cluster Head Election for Wireless Sensor Networks

Sensor Networks can perceive the extensive area by applying many sensor nodes because the size of sensor nodes is relatively small and cheap. Sensor nodes can transfer multi-hop data to sink nodes which are far away than sending and receiving distance. Generally sensor nodes are composed of a large size so it is difficult that much capacity is loaded on nodes. Many routing methods are proposed in order to raise energy efficiency in sensor networks field. There is a routing method based on structure as a composing method of network by cluster. Cluster technology consisting and maintaining network topology based on cluster is mostly studied in routing protocol. There are demerits that LEACH, EACHS shall be rest energy of all nodes and HEED does not guarantee the number of cluster head. Proposed energy efficiency of selected cluster head guarantees the number of cluster head which is a demerit of HEED and minimizes the node of DEAD.
