A Service Discovery Infrastructure for Heterogeneous Wired/Bluetooth Networks

Abstract

Specifications of some applications based on the Bluetooth protocol stack have already been standardized by the Bluetooth Special Interest Group. Those applications can however be accessed inside a piconet, while Bluetooth devices belonging to different piconets are not able so far of cooperating in a distributed application. In this paper, a framework is proposed that allows a Bluetooth device to search for services provided by other devices, also in case they are connected to different piconets that communicate through a wired network. The proposed framework has been implemented on a testbed platform and its suitability has been tested by using it to distribute a file transfer service over a heterogeneous network.
