Survey on Leach Protocol in WSN

Sarbjit Kaur ^[2] | Khushdeep Kaur ^[5]

Abstract: In wireless sensor networks (wsn) power is the most essential resource because each sensor node has limited batteries. So Many kinds of existing clustering protocols have been developed to balance and maximize lifetime of the sensor nodes in wireless sensor networks. In this dissertation we present T-LEACH which is a threshold-based cluster head replacement scheme for clustering protocols of wireless sensor networks. T-LEACH reduces the number of cluster head selection by using threshold of residual energy. Reducing the amount of head replacement and selection cost. The lifetime of the entire networks can be extended compared with the existing clustering protocols. Our simulation result shows T-LEACH provide better results as compare to LEACH in terms of balancing energy consumption and network lifetime
