A Sensor Data Processing System for Mobile Application Based Wetland Environment Context-aware

In recent years, with the development of USN(Ubiquitous Sensor Network) technology, the USN technology has, from all aspects of society, evolved in the field of environment, human health, buildings, and other construction sites. And nowadays it is being used as one of situation awareness services that can recognize the situation occurring in the region where USN is installed. However, in the USN environment, data is obtained from a very small sensor node via wireless communication and sensing, operation is conducted, and resources are limited. So in order to provide situation awareness service, QoS(Quality of Service) should be guaranteed and energy efficiency should be maximized.
