Grid and Fuzzy based Stable Energy-Efficient Clustering Algorithm for Heterogeneous Wireless Sensor Networks

This paper proposes a Grid and Fuzzy based Stable Energy-efficient Clustering (GFSEEC) Algorithm for Heterogeneous Wireless Sensor Networks (WSNs). It provides better stability period, throughput and network life time than LEACH, SEP and DEEC Protocols. This algorithm significantly improves the performance of two level as well as multilevel heterogeneous WSNs. It has been observed that with increase in stability period, lifetime of network reduces i.e. there is trade-off between stability period and network lifetime. Also the throughput of network is affected by stability period. Thus to provide better trade-off between stability period and network lifetime, this work has been further carried out in proposed GFSEEC algorithm. Simulation results justified that proposed algorithm improved stability period by 73.74%, 44.48%, 14.71% than LEACH, SEP and DEEC respectively under two level heterogeneous network and 26.87% than DEEC under multilevel heterogeneous network.
