Abstract
Energy resource constraint is an important issue in wireless sensor networks. An efficient solution to this issue is clustering approach; which markes the network nodes as cluster heads (CHs) and cluster members (CMs). In the clustering method cluster members send packets to the cluster head and CHs forward the received packets to the sink. CH selection mechanism has direct effect on the energy efficiency and network coverage of WSN. In this paper a new distributed clustering approach using fuzzy logic is proposed. Our proposed method uses Fuzzy logic to assign CH selection chance to network nodes in order to choose tentative and final CHs. simulation results demonstrate that our approach reachs to better network lifetime, energy efficiency and network coverage in comparison with UCFIA, GCA, and SCP.
