In this era of wireless sensor networks (WSNs) and IOTs, topological control for balancing load among sensor nodes necessitates an efficient scheme which can enhance the network lifespan and scalability. One of the major challenges in such schemes is to reduce the energy consumption so that utilization of battery power can be optimized. Moreover, existing schemes in the same domain considered some infrastructure based assumptions which make these schemes less efficient in current scenarios. This paper presents a new fuzzy logic based clustering protocol FL-HEED which is an extension of Hybrid Energy Efficient Distributed (HEED) protocol. It selects cluster heads (CH) based on three most familiar variables of network i.e. variability in distance from base station to nodes, coarser level of node numbers and the node’s battery level with the desired threshold values for fuzzy logical control unit. The performance of the proposed approach is shown in terms energy, network lifespan, packet delivery ratio and throughput of the given network comparing with the existing HEED protocol. FL-HEED achieves significant improvement over traditional HEED for lessen the overhead and uniform distribution of CH. All the simulations are done over MATLAB.
