Recent advances in electronics and wireless communications have provided the possibility to produce multifunctional, low energy consumption and low cost sensors. These sensors are able to communicate with each other over short distances. Considering the capabilities of fuzzy logic (such as low computational load, usability in distributed environments with inaccurate information, full compliance with the universe, etc.), it appears to be appropriate to be used to optimize energy consumption and fault tolerance in wireless sensor networks. The proposed protocol is called FFT-LEACH. The purpose of using this protocol is to increase fault tolerance and network lifetime and reduce energy consumption.
