In this paper we analyze the performance of a file sharing system based on the Bluetooth radio system. 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 thinking 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 structure, and propose a discriminatory processor sharing model which provides some qualitative insight into network performance. Based on the latter, we draw a connection to some classical results in the field of scheduling theory, which can provide useful guidelines for the design of effective scatternet management schemes.<br />

Abstract
In this paper we analyze the performance of a file sharing system based on the Bluetooth radio system. 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 thinking 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 structure, and propose a discriminatory processor sharing model which provides some qualitative insight into network performance. Based on the latter, we draw a connection to some classical results in the field of scheduling theory, which can provide useful guidelines for the design of effective scatternet management schemes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
