Integrating BLIP into Location-Aware System: A Service-Oriented Method

Abstract

Location-aware systems have attracted much attention from academic and industrial users. Location detection or positioning devices are required in order to get location information. Bluetooth is often used to detect the users' location in indoor location-aware applications. This paper integrates the Blip devices, which are based on Bluetooth technologies, into location-aware applications. A service oriented method is proposed to provide more flexibility and extensibility of the system. The prototype of CPH AirNotes with Blip devices is developed to show that the proposed method's effectiveness. Also the performance analysis of Blip is discussed according to experiences with CPH AirNotes.

Mobile Applications Provisioning Using Bluetooth Wireless Technology

“…Here the mobile client initiates the whole process by discovering the application over a wireless network using a suitable discovery application like a WAP; web browser etc. The user uses the HTTP protocol or GPRS to discover applications over a wireless network and then downloads them (both application descriptor file and application archive file) [3,6]. As inconveniences, 1) the user of the mobile phone has to go through the painful process of discovering applications.…”

“…As such the pushing process will be automatic without the awareness of the user of the mobile phone (note that it is not a thread to Bluetooth, as it only pushes objects into the inbox 2 http://netbeans.org/index.html, September 2010. 3 http://java.sun.com/javaone/online, September 2010. 4 A configuration is a Java virtual machine plus a minimal set of class libraries (http://download.oracle.com/javame/).…”

“…Some of these information propagator media are somehow very costly, therefore affecting most of these organizations. Minimizing the cost of propagating information by most of these IT technologies thus becomes a major cause for concern by most of these organizations [1][2][3]. In both cases, the operators or the mobile client have to go through an expensive middle man (Internet or mobile operators) irrespective of the distance between transceivers.…”

“…The challenge is to make a difference in the case of short range advertisement, precisely to bridge the "expensive middle man" in this context [1]. For the purpose of proximity marketing for example, commercial operators will want to call to the attention of his customers by pushing messages of any form onto the phones of such clients who we suppose are at a certain distance (for example most 100 meters) from him, this without depending on the services of any third parties (like mobile operators) [3,4]. But how does this commercial operator detect the presence of his targets, and push these messages to them?…”
