Abstract

Sensors have limited resources in terms of memory, energy and computational resources. Clustering has been proposed by researches to group a number of nodes to form a cluster that managed by cluster head. The advantage of this strategy is to minimize the number of message transmissions. In this paper, we propose clustering protocol called Centralized Dynamic Clustering CDC. Each cluster selects a node that serves as the cluster head. The cluster head is responsible for collecting the data from all the cluster members, aggregating the data, transmitting fused information to the base station and selecting new cluster head for next round. When node dies in cluster, the cluster head sends message to base station to forms clusters. Our experiment results show that CDC outperforms LEACH-C in term of communication overhead and latency in data delivery.
