Gaganpreet Kaur, Sandeep Waraich . Hybrid TB-LEACH Energy based Multihop Protocol. International Journal of Computer Applications. 95, 21 ( June 2014), 22-28. DOI=10.5120/16719-7039
Wireless sensor network is defined as the network composed of tiny and energy restricted sensor nodes. Sensor nodes collect the useful information from surrounding environment and deliver it to the base station. Sensor nodes have limited energy. Routing protocols must consume minimum energy in order to prolong the network lifetime. Clustering is most energy efficient technique. LEACH is one of the fundamental clustering based protocols. Many researchers had proposed changes in the LEACH protocol to overcome the drawbacks of LEACH protocol. In this paper, a hybrid protocol based on two extensions of LEACH protocol named TB-LEACH and CTPEDCA protocol has been proposed. This hybrid protocol also considers two additional factors residual energy of sensor nodes and distance of cluster head nodes from the base station. The performance of LEACH, TB-LEACH, CTPEDCA and proposed protocol is compared on the basis of parameters FND (First node die time), HND (Half Node die time), LND (Last Node die time) and remaining energy per round.
