WIRELESS SENSOR NETWORK SYSTEM AND EVENT DETECTION RATE IMPROVING METHOD IN WIRELESS SENSOR NETWORK

摘要

Disclosed are a wireless sensor network system and an event detection rate improving method in a wireless sensor network. According to the embodiments of the present invention, an event detection rate is improved by correcting event detection errors by using the temporal and spatial correlation of sensor data in the wireless sensor network. The present invention is applied to an unmanned monitoring boundary field for main facilities and a weak monitoring area which is inaccessible to a person in a military field and a public field by improving the reliability of target detection in the wireless sensor network.
