Cluster-based Energy-efficient Composite Event Detection for Wireless Sensor Networks
Wireless Sensor Networks (WSNs), well known communicating architectures today, are often used to detect the occurrence of some environmental events, such as pollution monitoring, forest fires detection, location and tracking, etc. In order to reduce irrelevant alarms, multiple attributes are used in the event detection process. In WSNs, communication is often by far more expensive and difficult to control than local computation within nodes. Therefore, it becomes critical to reduce the amount of data exchange within a WSN, in order to optimize the use of power and energy resources within nodes. Energy optimization is thus one of the most important aspects of the WSN design. There are already literature and projects dealing with the detection of composite events using data aggregation at intermediate nodes.
