Wireless Sensor Networks are event based systems that consists of a collection of autonomous sensor nodes that are spatially distributed in order tocooperatively monitor physical and environmental conditions. In Wireless Sensor Networks (WSN’s), congestion plays an important role in degrading theperformance of the network. Congestion in wireless sensor networks not only causes packet loss, but also leads to excessive energy consumption. Therefore congestion inWSNs needs to be controlled in order to prolong system lifetime. In addition, this is also necessary to improvefairness and provide better quality of service (QoS). In this paper we try to give a model for traffic aware routing based on fuzzy control concepts. To reach the goal, first weshould find the important parameters in routing, then investigate those parameters. After that we choose amechanism with the use of fuzzy controller. In thisregards, a solution is proposed which can improve the power that is a criterion for routing protocol. Beside, this method is appropriate for mass sensor networks because of its excessive overflow
