A review on fuzzy logic based clustering algorithms for wireless sensor networks

Today wireless sensor Networks (WSNs) has important role in various fields. Sensor networks contain many sensor nodes for the purpose of sensing the data from the environment of a particular region. The major design issue in this area is to optimize energy efficiency of a sensor node as the power source of sensor node is limited and also it is not feasible to replace or recharge the power source of sensor nodes. To increase the lifetime of a sensor network, the energy of sensor node must be utilized in optimized way. Sensor nodes are organized in a number of groups called cluster. Clustering is a technique to use the energy of network efficiently. In this paper, we present some fuzzy logic based clustering protocols researched by the active authors. In fuzzy logic based clustering protocols parameters used to create cluster head are residual energy, rechability from its nearest node, base station distance.
