An energy efficient clustering protocol with fuzzy logic for WSNs

This paper discusses a new protocol HEED-FL that follows the basic approach of the HEED protocol, but selects the cluster head by using fuzzy logic based on the three parameters: residual energy, degree of node, and distance between a sensor and base station. The HEED-FL protocol performs more than twelve times better than the original HEED protocol. It indeed performs better than many important protocols that have similar kind functionality as that of the HEED protocol.
