Abstract: Based on the research of LEACH protocol, a low energy-consumption routing protocol LEACH-E is proposed in this paper. The new protocol is characterized by each node will send information about its current location and energy level to the cluster head. The simulated algorithm will determine the clusters for that round. Finally, the experimental results show that LEACH-E performs better than LEACH protocol. It not only extends the lifetime of the network, but also improves the energy efficiency. Therefore LEACH-E protocol is an attempt to overcome the most common issue present in wireless sensor network energy efficiency. It is a popular energy efficient adaptive clustering algorithm that forms node clusters based on the received signal strength and uses these local cluster heads as routers to the base station.
