Lately, research for context-aware systems has risen significantly. New social needs require innovation new technology to build rich omnipresent computing spaces. Such spaces allow users to use services without caring of any interaction with the system. For bringing this in existence, some context awareness is needed so computers, based on their environment, can behave accordingly. Mobile Advertising is one of such new needs and has shown to have a large potential due to the very personal and intimate nature of the devices and the possibleness of reaching a broad range of targets. In this paper we discuss Bluetooth Advertisement System, a context-aware pervasive system for advertising in large commercial areas. Bluetooth Advertisement System uses Java and Bluetooth wireless technology making it a very client-specific system. We describe the overall architecture and discuss the execution steps taken to build this application.
