Improvement in Leach Protocol Using T-LEACH 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. This kind of protocols select cluster heads periodically, and they considered only How can we select cluster heads energy-efficiently or What is the best selection of cluster heads without Taking in considering energy-efficient period of the cluster heads replacement. Unlimited head selection may dissipate limited battery power of the entire 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
