Energy Efficient Event Driven Data Reporting System for Wireless Sensor Network
Power conservation is important in sensor devices since battery life is usually one of the critical components in extending the life time of the sensor network. Cluster technology that enables a group of sensor working closely to form a single cluster head, has been a booming research field in sensor network. When cluster heads cooperate with each other to forward their data to the base station, the cluster heads closer to the base station are burdened with heavy relay traffic and tend to die early, leaving areas of the network uncovered and causing network partition. To address the problem, the authors propose an event driven packet processing and redundant data eradication using in-network data processing before communicating such data to cluster head or sink.
