In wireless sensor networks（WSNs） sensors are serious limited by such resource as energy

bandwidth

etc

WSNs can achieve uniform energy distribution and prolong the lifetime through clustering.Current clustering algorithms of node’s energy and degrees is analysed

then a novel energy-efficient weighted clustering algorithm（EEWCA） in WSNs is proposed.According to the simulation result of the new algorithm

it can draw a conclusion that the EEWCA is an effective algorithm.
