Research
Our research on Internet of Things includes wireless sensor networks and low power wide area networks. In wireless sensor networks, our research enables sparse sensor deployment in large area for sub-GHz radios and fast data dissemination using rateless codings on computationally limited devices. We have also been exploring the possibilities of low power wide area networks (LPWAN) technology such as LoRa.
Our reasearch on Wi-Fi includes precice power delay profiling with commodity Wi-Fi devices, Atheros CSI tools, and SWAN which builds an array of stiched antennas extended from radio chains of commodity Wi-Fi devices.
