A wireless sensor network (WSN) consists of hundreds or thousands of energy-limited sensors. Distributing energy dissipation evenly throughout the sensors and saving energy are important goals in designing of WSN protocol. In this paper, we propose an improved energy-efficient algorithm based on L-DCHS (IEAL), it adds a cluster head in each cluster with a novel method, and prolong the steady-state phase time. Additionally, we redefine the candidate set in each round. Simulations show that IEAL can achieve a longer system lifetime and save energy dissipation.
