An Unified Model of Semantic Description Format For Devices in Bluetooth

Piconet

Disclosed is a framework for inter-communication among a multitude of diverse devices in a Bluetooth piconet, using a unified sematic description language.

The wireless Bluetooth communication protocol is poised to have a remarkable influence on people's lives in the near future. Smart homes will have devices interconnected by Bluetooth piconets which will be connected into scatternets and also to the Internet.

In this environment of a multiplicity of devices which speak different languages, it will be important to have a unified semantic description language through which these devices can interoperate in the piconet. Since the piconet communication is master-slave, there has to be a mechanism to uniformly transmit device information, properties and commands in a device/language independent ways.

Recently, there has been a proliferation of interest in formats for semantic information capture, especially through Resource Description Format (RDF). In this disclosure, we propose a framework for the inter-communication of resource property/capability/description among a multitude of diverse devices in a Bluetooth piconet.

A Bluetooth piconet is expected to have a multiplicity of devices, printers, cell phones, handhelds, DVD players, TV, VCRs etc. Each of these devices have their own semantic representation languages. However, one of the chief advantages of using Bluetooth is the ability to control multiple, diverse devices through a single piconet (or a scatternet). Consider the following scenario where a Bluetooth piconet comprising of a thermostat (to control the home temperature) is also connected to the Internet through a LAN access point. It will be very useful if the owner can issue control commands to the thermostat remotely, e.g. to turn up the heat about 15 minutes before she is leaving her office for home. For this scenario to work, the thermostat interface has to be exported to the piconet master, which then has to issue the thermostat control commands. However, most of these device interfaces do not interoperate. We therefore, need a uniform mechanism (at the application level) through which Bluetooth enabled devices can interoperate and also be controlled by a master (which will probably be a completely different...
