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. |
