Abstract :In Wireless Sensor Networks (WSNs), the sensor nodes have limited energy resources with their mostly irreplaceable batteries. . This makes to encourage design protocols that are energy efficient to provide a longer network life time. This paper proposes a method to divide the sensor network into equal-size grids (the grids are considered as clusters), selecting Cluster Head (CH) and Vice Cluster Head (VCH) for each grid by using Fuzzy Logic System (FLS). Since the CH being the central node and performing additional tasks in a grid often results in early energy drain, the VCHs are introduced here as an additional internal resource to replace CHs in the network. Unlike other typical hierarchical routing protocols, the CHs are not changed per round, rather they are replaced on-demand in order to reduce energy consumption. We analyze and compare our proposal in the MATLAB with the well-known cluster-based protocol, LEACH and its modified version MODLEACH. The results show a significant improvement in delivery ratio, energy consumption and network lifetime.Keywords : Cluster head, fuzzy logic system, grid, vice cluster head, wireless sensor network
