Bluetooth & Jini 2

Msg.) Date: 2000-08-01
The question is often asked how does bluetooth and Jini
(Sun's Java CORBA-like connection technology) interact and relate to each
other. The Jini system is a Java-centric system on the network, assuming and
requiring that the communication between a client and the services used by
that client are accomplished through a Java interface.
On looking at the basic architecture of Jini and
Bluetooth, one feels that they're sometimes similar in the way they recognise
devices in the environment, also they both aim to handle interaction between
various devices. However the two technologies are fundamentally different,and
their are several points that arise when you try to compare the two and how
they function
- Bluetooth essentially provides a physical medium by which one may
utilise the JINI services. JINI is more an API for discovering services
while Bluetooth enables the use of JINI.
- For the device discovery procedures, Bluetooth does provide its own very
simple service discovery protocol, although it is not as robust as Jini or
other industry general-purpose discovery protocols.
- Interoperation between the two might also cause problems. Bluetooth
could be a transport over which Jini could operate, Bluetooth does not
(today) provide standard IP networking function; thus Jini over Bluetooth
transports is not a done deal, although the Bluetooth SIG is beginning
discussions about this.
While the two technologies might coexist quite well ,
and perhaps might even have some synergy in the future, they're not really
comparable. They operate at different "layers" (loose term) and
perform different tasks/functions.
Note: A simple guide on Jini is available
here, also see ' Bluetooth & Jini 1'.
