Fuzzy TADR: A fuzzy extension to TADR algorithm for congestion control in wirless sensor network

Wireless Sensor Networks are the systems which are event based. they consist of a group of independent sensor nodes. these nodes are spread throughout the space and cooperatively check physical and environmental conditions. In Wireless Sensor Networks (WSN´s), congestion plays an important part in lowering the function of the network. Congestion in wireless sensor networks not only causes packet loss, but also results in fulsome energy consumption. Therefore congestion must be controlled in WSNs to lengthen system lifetime. In addition, this is also essential to strengthen fairness and provide better quality of service (QoS). In this paper we try to present a model for traffic aware routing based on fuzzy control concepts. To reach the goal, first we should find the significant parameters in routing, then investigate those parameters. After that we choose a mechanism with the help of fuzzy controller. In this field, a solution is proposed. This solution 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.
