METHOD FOR AUTOMATICALLY SELECTING A CLUSTER HEADER IN A WIRELESS SENSOR NETWORK AND FOR DYNAMICALLY CONFIGURING A SECURE WIRELESS SENSOR NETWORK

摘要

A method for automatically selecting a cluster header in a wireless sensor network and a method for dynamically configuring a security wireless sensor network are provided to automatically select a cluster header in consideration of the remaining energy capacity or hardware capability. Each normal node broadcasts its own capability characteristics information, identification information of a cluster to which each normal node belongs and cluster header select information including its own identification information to neighbor nodes. Each normal node determines whether it is selected as a cluster header based on the cluster header select information received from the neighbor nodes. The capability characteristics information is set according to at least one of a remaining energy capacity, hardware capability and an amount of energy consumption.
