摘要：In the ubiquitous computing services are heterogeneous in nature. To be pervasive, these services should bedefined in terms of their functionality and capabilities.The vision of ubiquitous computing refers to the creation ofenvironments saturated with a spectrum of heterogeneous computing and communication capabilities, which seamlesslyintegrate with the physical world. Such capabilities cover the spectrum ranging from traditional devices (e.g., speakers),wireless mobile devices (e.g., cell phones) to smart devices (e.g., badges, sensors, intelligent appliances). In ubiquitousenvironments, users are surrounded by different kind of computing devices offering services of different types. As usersneed to discover and interoperate with such services, service discovery represents a crucial functionality. Service discoveryprotocols (SDP) are needed to discover and use the services in ubiquitous environments.This paper presents discovery of a Bluetooth device using SDP. The SDP defined in the Bluetooth specification isintended to address the unique characteristics of the Bluetooth environment. In this application, a PDA will find a Bluetoothdevice if any comes in range or the PDA goes in range of that device.
