Wireless Sensor Network (WSN) is a wireless network of small nodes with sensing capabilities, computation, and wireless communication. Each sensor collects data from the monitored area (such as temperature, sound, vibration, pressure, motion or pollutants). Then it sends data back to the base station BS. In Wireless Sensor Networks (WSN), the power resource of sensor nodes is limited, energy dissipation and network lifetime are the most important parameters to consider in the design of routing protocols for sensor networks. In this paper, we propose a new approach of LEACH (Low Energy Adaptive Clustering Hierarchy) protocol, which aims to reduce energy consumption by using a second hierarchical level in cluster head selection for data transmission process. Moreover, it uses a new random formula of probability based on the ratio between residual energy of each node and the remaining energy of the network. Finally, Simulation results show that the improved method can reduce the network consumption energy greatly and lengthens the network lifetime efficiently.
