A new method for flat routing in wireless sensor networks using fuzzy logic

Wireless sensor networks (WSNs) are consist of hundreds or thousands small nodes called sensors that are connected to each other to do specific tasks. Routing is one of the main operations that nodes are doing in WSN network. Routing consist of selecting the next node by each node in the WSN. A variety of methods is proposed for routing. But in the field of using fuzzy logic approach for flat routing has rarely been studied. Since more than one parameter is considered in selecting the next node, using fuzzy logic will be useful. Our proposed method is a fully distributed method and all operations are done by the nodes. Use of fuzzy logic increases speed, accuracy and power of the routing. Also since the processes are completely local, this structure is very useful for environments that require real-time processing. Evaluations show that our method dramatically increases the network lifetime.
