Energy conservation is very important task for wireless sensor networks (WSN), since external power sources are typically unavailable and the replacement of batteries is clearly impractical for large networks. A classical protocol widely used in WSN, called LEACH (low-energy adaptive clustering hierarchy), is a cluster-based protocol which aims at reducing energy consumption in the network. However, it has some drawbacks. This paper proposes the CHEATS (Cluster-Head Election Algorithm Using a Takagi-Sugeno Fuzzy System) protocol, an improvement on the LEACH protocol whose goal is to increase energy efficiency in terms of network lifetime using fuzzy logic through a Takagi-Sugeno system to calculate the probability of election of candidates for cluster-head. Simulation results have shown that the protocol proposed could prolong the lifetime and increase the throughput of the network.
