CCTS with Two Clustering Techniques for Time Synchronization in Wireless Sensor Network

A new time synchronization algorithm for wireless sensor networks, named clustered consensus time synchronization (CCTS) with 2 clustering method LEACH and FCM. However, 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) and for increasing the accuracy of the clustering method, incorporated Fuzzy C Means (FCM) clustering to this algorithm. By using this methods can increase the convergence rate and also can reduce communication traffic.
