Fuzzy Logic Based Effective Clustering of Homogeneous Wireless Sensor Networks for Mobile Sink

In recent trends, wireless sensor networks (WSNs) are mostly used for a number of applications where conventional networks are infeasible. To perform WSN operation, a number of sensors are deployed in desired network cross-section. Since sensors are embedded with limited resources, it has the limitation while using sensor node's battery power. Clustering schemes are one of them which can utilize sensor's power effectively in WSNs. In this paper, a Fuzzy Logic based Effective Clustering (FLEC) of Homogeneous Wireless Sensor Networks for Mobile Sink has been introduced. The problem associated with existing protocol, A Fuzzy logic based Clustering Algorithm for WSN to extend the Network Lifetime (LEACH-Fuzzy), is resolved in FLEC by utilizing the concept of average energy based probability and average threshold for appropriate cluster heads (CHs) selection. In addition, average energy of CHs has been also included in Fuzzy descriptors to make proper super cluster head (SCH) election among CHs. Simulation results justify that the proposed FLEC scheme outperforms over LEACH, DEEC, and LEACH-Fuzzy protocols.
