Construction of smart middleware system to support incomplete data based on WSN

It currently is used for situation awareness service that is perceptible on what happens in the region where USN is installed. USN environment should maximize the energy efficiency. Sensing data from a very tiny sensor node and performing operations, and utilizing limited resources. This study designs and implements Active Smart Middleware, the USN Middleware which may possibly maximize data stability and energy efficiency in the situation awareness service utilizing USN technology. And the modules that provide services were mounted using smart phones in order to increase the ease and accessibility of smart phone users. It implements application services to evaluate performance, and as a result of evaluation, energy efficient query-processing and incomplete data throughput have been improved compared to the existing USN Middleware system. In addition, it designs and develops smart phone support module for the possible support of smart phones in considerations of interface in terms of users.
