Fuzzy C Means Time Synchronization for Wireless Sensor Network
نویسنده
چکیده
A new time synchronization algorithm for wireless sensor networks, named clustered consensus time synchronization (CCTS). To obtain faster convergence in the clock synchronization of node and better energy efficiency, the clustering technique is incorporated into the algorithm. The CCTS includes two parts: 1) intra cluster time synchronization and 2) inter cluster time synchronization.In the intra cluster time synchronization,the cluster head is responsible for exchanging messages within the cluster.In the inter cluster time synchronization, cluster heads exchange messages via gate-way nodes. The clustering technique used is LEACH (Low Energy Adaptive Clustering Hierarchy).In this algorithm theclusterheads will change accordingly after some time, so cluster-heads have some energy difference. For increasing the accuracy of the clustering method, incorporated Fuzzy C Means (FCM) clustering to this algorithm. By using this method can increase the convergence rate and also can reduce communication traffic.
