Uneven Cluster-Routing Protocol of Base on Energy for Wireless Sensor Networks

For severe energy constraint problem of wireless sensor networks, a non-uniform energy efficient clustering routing protocol (EUCRP) is proposed based on the analysis of the existing clustering routing protocol the characteristics and shortcomings. In EUCRP, we use a limiting cluster size optimization formation algorithm to produce clusters in descending order of the size of the cluster. Improved multi-hop inter-cluster data forwarding, saving energy cluster head and energy consumption of inter-cluster is balanced. Propose using “watering pot path” in the last hop to effectively solve the “hot zone” problem caused by uneven load energy. Simulation results show that the protocol can effectively reduce network energy consumption and prolong the network lifetime.
