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.
