Abstract : Wireless Sensor Network (WSN) comprises various sensors. They sense data based on various physical phenomena parameters and transmit the same to base station by forwarding data though intermediate nodes which also behave like relaying nodes in route. However there are some resource constraints attached to them like energy and memory which attract all attention towards an energy efficient routing protocol. There exist numerous such protocols and the most prominent and effective one is Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol and its family. The lifetime of nodes and network depends on routing protocol. This paper covers some protocols under LEACH family like TL-LEACH, M-LEACH, DD-LEACH and DD-TL-LEACH. Finally, proposed work enhances the DD-TL-LEACH protocol in terms of energy by considering three major parameters size of packets, energy, and distance between node and BS.
