Modified approach for routing and clustering in sensor network using fuzzy logic control

This paper proposes new modified Enhanced Stable Election Protocol based upon the fuzzy logic control. The scheme takes into account restricted resources i.e. battery level and optimizes its use such that the lifetime for the working of Enhanced SEP is prolonged. In accordance to that, weighted probability is calculated, for efficient election of cluster head and optimised cluster formation. Fuzzy logic control based Enhanced SEP (FLC-SEPE) minimises energy consumption required by sensor nodes for communication, mobility, Cluster Head election, and load balancing by optimising the whole process, hence increasing the lifetime of the wireless sensor network. Simulation results have shown significant improvement of FLC-SEPE, over SEP-E. Performance improvement achieved for the two cases discussed is about 76.5% and 103% respectively.
