Design of a fall detection system based on wireless sensor network

In this paper, we propose the fall detection and localized caring system to effectively detect the postures of a human and provide a service of remote connection with health care center. Especially, when an aged people or a patient suffered from epilepsy, diabetes, and hypertension fall, it will cause more damage than a normal people. The system can inform the care center automatically through the wireless sensor network, and provide the rapid information of the incident for their family through the mobile phone. It also provides the location of incident for immediate rescue by dispatching medical staffs from the center. The experimental results show that our system achieves about 100% of the accuracy for detecting the fall of a people, and provides the care services effectively.
