摘要：
Energy efficiency is the most important issue in research of wireless sensor networks while the routing protocol plays an import role in achieving energy efficiency in WSN. In this paper, the deficiencies of LEACH are analyzed and an improved cluster-based energy efficient routing algorithm called ECHC is proposed. An election weight taking account of the residual energy and concentration of nodes for cluster-head election is introduced in the proposed algorithm. The algorithm also defines a new criterion for non-cluster nodes to choose its cluster head. Experiments are conducted to prove the efficiency of ECHC.
