The typical task of Wireless Sensor Networks is to gather environmental data with the aim to detect application-relevant events. Such events cover a range of security relevant events from trespassing of restricted areas via critical frequencies arising on bridges through to a harmful movement during a physical rehabilitation. During observation, sensor nodes are collecting a huge amount of data that need to be transferred to a central processor. This procedure is very energy consuming and shortens the lifetime of the sensor network.
VIVE validates a distributed event detection that provides a pattern matching based framework for wireless sensor networks. Groups of sensor nodes share information in a cooperative way which allows to evaluate events autonomously within the network. VIVE investigates new applications that benefit of an in-network evaluation of predefined events. The wireless Compounds of sensor nodes are sharing information in a cooperative way which allows to evaluate events autonomously within the network. Transferred data is reduced and evaluated within the network which allows short response time on events. As a result, the lifetime of the whole network will be enhanced.
