LELE: Leader Election with Load Balancing Energy in Wireless Sensor Network

In this article the LEACH (low energy adaptive clustering hierarchy) in the homogeneous wireless sensor networks (WSNs) was considered and a new protocol with an approach toward promoting LEACH was introduced. In the new protocol which is called LELE (leader election with load balancing energy), the major work was how to elect the leader which was done through changing the sensor´s energy, LELE protocol compares the amount of energy and distance of a node with its neighbouring sensors to elect it as leader. And, finally the sensor with the higher energy (has more suitable position as compared with the neighbouring nodes ) for chosen as the leader. After simulating the new protocol and comparing it with the previous protocol it was well observed that LELE in addition to balancing the energy and throughput, increases the network´s lifetime as compared with that of LEACH. In the new protocol the time distance between the observation of the first dead sensor and the last sensor´s having lost its energy is so short.
