Wireless sensor networks（ WSNs） is consists of nodes which are small in size

low power consumption

low price. Until now

many protocols have been proposed

they are different in many aspects

like parameters selection

approach and so on. Among this

clustering routing protocol is one of the most famous approach

which is the core technology in WSNs that is widely used in environmental

medical and other fields. In clustering structure

the cluster head（ CH） node gather information of other nodes in cluster for data fusion

and then transmit them to base station. It’s really necessary to carry out comparative study on some typical clustering structure algorithm.
