Outline of Final Research Achievements

In this project, we developed (1) cross-technology signal detection method to detect WiFi signals on sensor node, (2) WiFi AP operating channel estimation method using sensor node, and (3) WiFi interference detection scheme during ZigBee communication. Using the cross-technology signal detection scheme, we extracted information on WiFi APs around sensor nodes including distance and traffic. We also presented a WiFi interference avoidance scheme based on the collected AP information. This project is tackling challenging tasks and faces many new challenges. We therefore changed our research plan and developed fundamental techniques for our final goal.
