Abstract-- In this paper we analyze the performance of a file
sharing system based on the Bluetooth technology. Files are stored
in a server to which clients may connect by setting up a Bluetooth
connection. Files are transmitted over the TCP/IP protocol suite, and
users alternate between activity and idle periods. In the first part of
the paper we concentrate on the simplest configuration, an isolated
piconet, and propose a processor sharing model for the computation
of the mean session delay for interactive users. Then, we focus on the
more complex scatternet configuration, and propose a discriminatory
processor sharing model which provides insight into the network
