Wireless Sensor Network (WSN) is infrastructure based. Sensors usually rely on their battery for power, which cannot be recharge or replaced. To reduce the energy consumption focus is on the cluster stability. A new protocol is proposed called OEE-LEACH for cluster stability by adding parameter in distributive Cluster Setup function in terms of energy of nodes, number of nodes and average distance between CH and member nodes by putting weights alpha, beta and gamma respectively. The coefficient of parameters is the OEE-LEACH protocol is better than in terms of energy performance, throughput, and packet delivery ratio than LEACH.
