Sensor networks can perceive the extensive area by application of many sensor nodes because the size of sensor nodes is small and cheap. Sensor nodes can transfer multi-hop data to sink nodes which is far away than sending and receiving distance. Many routing methods are proposed in order to raise energy efficiency in sensor networks filled. 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.
