I'm working on the machine-to-machine applications in Mobility First project. It is specifically focused in sensor network. In Mobility First network, sensors, like other mobile devices, will be givien Global Unique IDs(GUID) as their names recognizable to network. With GUIDs, sensor data are no longer isolated information which requires application specific gateways. M2M applications will be able to publish and access sensor data from different vendors by GUID, not requiring application specific gateways, through Mobility First network, which has a Global Name Resolution Service(GNRS) allowing fast updates on attach points, self-certifying of data source/destination, and dynamic connections of sensors.

Porject approach

Sensor Networks

  • Sensor network I: Pipsqueak, 900MHz sensors, processed under "Grail rtls". ​Grail
  • Sensor network II: WINS 2.4GHz sensors, processed under windows API.

Approach

  • Step 1. Application level integration (Currently working on): integrate two sensor networks under Grail system.

appIntegration

  • Step 2. Core network integration for Mobility First network (Future work): including sensor and Context(sensor data with certain context) GUID assignment, publish and lookup server.

About Application Level Integration

Data out of grail system could match different kinds of GUID in the Mobility First network more easily. So we will integrate two different groups of sensor networks from different vendors into grail. And through grail, we will publish and access sensor data by GUID through Mobility First network. The function of grail could be broken into five layers. You can find more information about those layers here. ​Grail_layers

Work Log

June 20: Modify network layer between Wins which is under Windows Visual Studio and Grail system which is under Linux.

According grail communication protocol, implement handshake function under windows visula studio.

June 21: Test and debug handshake communication between Wins and Grail.

June 22: Fetch updated Grail system code. Modify handshake protocol.

June 23: Modify Wins according to updated Grail. Test new handshake protocol between Wins and grail.

July 15: Intergration of Wins with Grail system on aggregator layer is implemented.
