摘要:
Provided is method of forming a cluster individually by each sensor node over a sensor network, in which each sensor node has cluster information and authority to assign cluster membership and recognizes a sensor node that is not a cluster member in a radius of the cluster in order to include the recognized sensor node in the cluster as a cluster member. The sensor node that becomes a member of the cluster wirelessly receives an application of the cluster in order to be upgraded. Thus, after initial sensor node setting, a cluster can be formed automatically and a program suitable for each cluster can be upgraded without human intervention.
