Research Projects

IoTP: Internet of Things Protocols
We implemented and demonstrated the world 1st end-to-end IPv6 solution in March 2012  based on Bluetooth Low Energy (BT-LE), which is also known as BT4.0. BT-LE devices/sensors can operate for months or even years on tiny coin-cell batteries. BT-LE is emerging in applications like healthcare, sports and fitness, security, and home entertainment.

  • Bluetooth Core Spec V4.0 is available here. The devices that support BT-LE can be found here. Transmission of IPv6 Packets over Bluetooth Low Energy IETF draft can be found here.

HAIP: High Accuracy Indoor Positioning
provides the highest level of accuracy (<1m) with the lowest power consumption and installation cost in the world. It is based on Bluetooth Low Energy (BT LE) or BT4.0 technology and AoA (Angle of Arrival) or AoD (Angle of Departure) principle. We implemented the world first Mobile Centric mode indoor positioning system demo, which has been demonstrated in In-Location Alliance plenary in June 2013.

  • HAIP video introduction is here.
  • HAIP is being standardized in BT-SIG, and expected to appear in next release of Bluetooth Spec.

uSD entry: universal Sensor Data entry
a universal mobile gateway solution for accessing wireless sensor networks. Without need for drivers, you can expand hardware through general memory interface; an example is to enable mobile devices access wireless sensors in surroundings using a special SD card (namely, uSD card: universal Sensor Data card). We kicked off a public uSD card trial in 10+ China universities in Dec.2009. One paper is accepted by MobiCom'10 which uses uSD card to discover Wifi hotspot.

mWSN: mobile enabled Wireless Sensor Networks
leverage mobile user base as collectors for sensor data, realize large scale data gathering wireless sensor networks through mobile sinks.
