Intelligent sensor data and mobile cloud integration for context awareness vehicular applications (2014 @UBC)
  • What's this? A mobile application that integrates both motion detection sensor and OBD data to help drivers to combat fatigue and negative emotions during driving. 
  • Techniques at-a-glance:                              1. SQLite database and lightweight ontology computation methods for storing and interpreting the integrated sensor data and mobile devices.     2. RESTful web service, Apache ODE, JBoss jBPM and a series of open source packages for running the cloud platform to achieve efficient communication and computation with mobile devices.

MAC Protocol Design for Vehicular Power Line Communication (VPLC) (2014-Now @UBC)
  • Motivation: In a car, the number of “intelligent” sensors, computers and electronic control unit (ECU), is continuously increasing. Increase the number of dedicated wires, cables, shielded cables. Weight, cost and reliability (connectors).
  • Question: Why putting an additional cable between two ECUs for exchanging data since there are already connected to the DC power line.
  • Our solution: Use the DC PL as a physical support for the transmission. Thanks to the development of X-by-wire technique (replacing mechanical transmission by data transmission).

Surfing the Internet-of-Things (2011-Now @Orange, UBC)
  • Motivation: To revolutionize the design of Internet-of-Things (IoT) and enable universal connectivity and management to resource constrained devices, it is advantageous to develop lightweight radio and IPv6 protocol stack for sensor networks and thus bring more value-added services into our smart plans.
  • What’s it?
    A full IPv6 solution to realize easy access from a smart phone or PC to a sensor device via home gateway. 
  • Restful interface for data access: Software development on OpenWRT firmware of gateway to realize HTTP/CoAP proxy for remote RESTful access.
