Research on QoE/QoS and Economics in Wireless Multimedia Communication Networks:


Multimedia is the dominating traffic in internet and nowadays unreliable wireless access networks. Mobile devices are typical energy-constrained and resource limited.


Our research objective is to design a new solution to accommodate quality multimedia service over energy-constrained wireless networks, which are typical unreliable. New approaches includes economics-driven algorithms, and joint design of codec and protocols.





Prototype of energy efficient mobile wireless multimedia systems. CEENBoTs carrying Gumstix computer boards taking camera pictures, invoking light-weight JPEG2000 codec and WiFi drivers in Linux OS, transmitting multimedia streams to client computers. Graduate and undergraduate students are working on theoretical model and experimental testing of wireless network performance.


Research on Wireless Sensor Networks, Cyber Physical Systems and Internet of Things:


Low cost wireless sensor devices provide ubiquitous data access bridging the internet and the physical world. Our current research is focused on optimization and scheduling algorithm design to bridge the gap between emerging applications and energy-constrained internet of things.


Applications include real-time soil condition monitoring in precision agriculture, intelligent transportation system design using heads-up display and smart-phone for driver safety warning, as well as supply chain management for pharmacy anti-counterfeiting.
