Wireless sensor network is made up of sensor node which is having constrained power, confined size and price. Function of sensor node is to sense physical data from environment; process this data and sends this data to sink. To defeat this hurdle, data need to send in appropriate manner by using routing protocol. By using fuzzy logic related clustering, optimal number of cluster head can be selected, distribution of cluster head is achieved and power consumption is also reduced. Different fuzzy related clustering method is described here.
