Clustering in wireless sensor networks (WSNs) attracted academia and industry alike due to the wide range of their applications. For the limited resources of WSNs, many algorithms have been proposed for efficient clustering. One of the most famous clustering algorithms is hybrid energy efficient distributed (HEED) protocol. At the same time, security is another challenge due to the critical information transferred. In this paper, we propose a modified HEED, entitled S2HEED, in which a fuzzy logic is used to enhance the cluster head selection criteria for efficient distribution in the field. In addition, we propose a security framework that can be used along with HEED. Based on extensive experiments, our proposals in this paper show that fuzzy logic approach prolongs the network lifetime and the proposed framework defend the network from different attacks like Sinkhole, Sybil attack, Hello flooding attack and selective forwarding in addition to the replay attack.
