摘要：Wireless sensor network (WSN) is a wirelessly interconnected network; it has increased massively due to the vast potential of smart wireless sensors to connect the physical globe with the virtual globe. Sensor nodes are used for monitoring and tracking fields they sense many environment conditions such as vibration, temperature, speed and even pollution level and many other such environmental conditions. Thus it's quite common to deploy WSs in hostile environments where there are no electricity sources so SN get powered from its battery and this battery get evacuated with time. However decreasing power energy consumption in WSN is one of the most essential keys to challenge WSN lifespan, hence Low energy adaptive clustering hierarchical routing protocol (LEACH) has been suggested to enhance network lifespan. This protocol is based on clustering technique; each cluster of the network has cluster members CMs and one chief cluster named cluster head CH responsible for routing data to the BS. In this paper, we will present an algorithm based on LEACH to optimize energy efficiency level and improve life time of the WSN, Moreover, a comparison of this algorithm and the pure LEACH is being done. Finally simulation results shows that the proposed protocol beats pure LEACH in terms of network power consumption saving and network lifetime.
