A Routing Algorithm based on Fuzzy Clustering and Minimum Cost Tree (FCMCT) in Wireless SensorNetwork

Nowadays, wireless sensor network has been of interest to investigators and thegreatest challenge in this part is the limited energy of sensors. Sensors usually arein the harsh environments and transit in these environments is hard and impossibleand moreover the nodes use non- replaceable batteries. Because of this, savingenergy is very important. In this paper we tried to decrease hard and complexcomputing with using soft computing such as fuzzy logic and we used it in clusterhead selection part. Hard and complex computing can waist energy, because of this,we used some techniques to solve this problem. Minimum cost tree (MCT) helps tofind minimum path, so we used this technique for intra cluster routing and againmore over we used distributed source coding (DSC) technique for aggregating data.Finally all of methods could reduce energy consumption and increased networklifetime. Proposed algorithm is called FCMCT and simulation and results showimprovement.
