Abstract

The number of wireless sensor network nodes is huge and the energy of a single node is limited, so the primary goal of routing protocol design is to improve energy efficiency and prolong the network lifetime. This paper chooses LEACH routing protocol as the research focus, analyzes the implementation of the routing algorithm, and proposes an improved E-LEACH routing algorithm based on the characteristics of sensor node energy and network lifetime. The NS2 simulation software is used to simulate the routing protocol, and the validity of the protocol is verified.
