EE-LEACH: Energy Enhancement in LEACH using Fuzzy Logic for Homogeneous WSN

The energy saving of wireless sensor nodes, which are organize in an unfriendly environment, is a paramount challenge for the design of wireless sensor networks (WSNs). WSN have a lot of design issues in which hotspots problem is one of them. Hotspot problems occur when the cluster head (CH) near the BS can die prematurely due to uneven energy shortages resulting in the partitioning of the network. To deal with the issue of hotspots or energy holes, balanced energy dissipation is demonstrated in wireless sensor networks. The main goal of this proposed protocol is to prolong the lifespan of wireless sensor networks, and balance the load of a network in terms of equal energy dissipation. CH selection and cluster formation are discussed in proposed protocol. CH select via rank using fuzzy inference systems following cluster formation in WSN. The performance of the proposed protocol EE-LEACH is evaluated for network lifespan, number of packets delivered, and stability period with existing protocol SCHFTL and DFCR. Experimental results show that the proposed protocol EE-LEACH performs significantly better than existing protocol.
