Wireless Sensor Network (WSN) needs an energy conservation communication protocols to reduce the energy consumption as much as possible. But the lifetime of sensor network greatly affected due to the battery of a node. Radio irregularity and fading in multi-hop WSN also affect lifetime of a sensor. Various cluster-based schemes are proposed as a solution for this problem. The proposed schemes focus on the clustering of network for conserve the energy of a network. The performance of the proposed system is evaluated in terms of energy efficiency and reliability.
