Abstract
A wireless sensor network system and a cluster management method thereof. The wireless sensor network system includes at least one cluster having at least one sensor node for collecting sensing data, and a cluster head for aggregating the sensing data from the at least one sensor node. A sink node collects the aggregated sensing data from the at least one cluster, wherein the cluster head of a first cluster determines a cluster size of the first cluster, and when the first cluster is a master cluster and the cluster size of the first cluster is less than a threshold size, merges, the first cluster into a second master cluster, and switches the first cluster to a slave cluster. In each cluster, management efficiency can thereby be maintained within a specified range, and the lifetime of a wireless sensor network can be prolonged by reducing energy consumption.
