摘要
A system for monitoring context in real-time based on the USN is provided to minimize traffic in the USN and enable a monitoring network to fully perform a basic function even if a monitoring server is not operated owing to an obstacle by selecting a single-way asynchronous communication mode centered on an alarm byte. A plurality of sensor nodes forming a context sensor node comprises a context data recognizer for recognizing context data, a context discriminator for generating/interpreting alarm byte data suitable for the recognized context, and a wireless communication protocol for wirelessly transmitting the generated alarm byte data to related nodes in a single way. The context sensor node comprises a local monitoring node classified into a fire/disaster monitoring node(10) and an anti-thief monitoring node(12), an alarm node classified into a local and global alarm node(50) and a video monitoring node(60n) providing video for an area by using an information level and position information of the node received from the local monitoring node. The local alarm node is classified into a fixed local alarm node(42) and a plurality of portable local alarm nodes(44,44n).
