Abstract: Wireless Sensor Networks (WSNs) are a set of sensor nodes. They are used in various area monitoring applications; the nodes communicate to obtain data collected by the base station or a receiving node. Nodes have two roles. The first is to detect the data, and the second is to act as relay nodes. The latter function is considered for intermediate nodes, where this role is more costly for nodes that are closed to the base station due to high traffic load. In this paper, we proposed a Fuzzy Independent Circular Zones Protocol (FICZP). In our protocol, cluster heads election is based on two different measures, one representing by nodes number of neighbours and the second representing by nodes remaining energy. These two metrics are merged by the fuzzy logic approach for defining nodes lifetime cost-values. Fuzzy Independent Circular Zones Protocol compared to Stable Election Protocol (SEP), Zonal-Stable Election Protocol (Z-SEP), and other recent proposed protocols. Simulation results prove that the proposed protocol performs better than its predecessors in network lifetime extension, first and last dead node and network stability.
