Abstract
Power consumption is always an important element for Wireless Sensor Network (WSN). The energy is the main constraint should be considered when designing the algorithm, protocol or the methods. Clustering is one of the effective methods to use in designing low energy usage in WSN. In the clustering, the appropriate cluster head selection can drastically reduce the energy consumption and prolong the lifetime of the network. This paper proposes the use of ranking table to select cluster head based on the Fuzzy Logic approach. The multi-tier clustering will be used to improve the energy consumption of WSN. Thus, this approach will increase the network lifetime and reduce the energy consumption of nodes while selecting the cluster head.
