In this paper, we describe TinyObj service discovery model, which uses short wireless packet broadcasts for service discovery within a user’s vicinity. We present a prototype implementation for the discovery model including the hardware and software development of a wireless discovery device. The developed wireless device, called Buoy, can be used as an independent service discovery device or as an attachment for cellular phones. The aim of the design is to provide the basic functionality for service discovery in ubiquitous environment. The developed software includes a uniform user interface that makes the system expandable and customizable. Indeed, a user can easily add, advertise, discover and remove any services in the system.
