The Java Community Process (JCP) has recently finalized a Java Specification Request (JSR) to cope with location-awareness (JSR-179) in Connected Limited Device Configuration (CLDC). Implementations of this specification may rely on several location methods, including satellite based methods like GPS, as well as short-range positioning methods based on Received Signal Strength (RSS). Though RSS is a good location fingerprint for indoor positioning, no standard technique to tailor RSS-based approaches to the JSR-179 API has been proposed yet. In this paper we propose such a technique, and we evaluate its effectiveness through a Bluetooth-based prototype. Specifically, we show how to extend the Java APIs for Bluetooth (JSR-82) in order to provide the Location API with RSS-based position-information. Moreover, we show how to adapt RSS-based approaches to Location-API's semantics. Our solution is based on the insertion of a specific component into the JSR-82 API. This is in charge of producing all the information needed to build Location objects as defined in the JSR-179. We evaluate the effectiveness of the approach by examining preliminary experimental results obtained from the first system prototype.

Abstract

The Java Community Process (JCP) has recently finalized a Java Specification Request (JSR) to cope with location-awareness (JSR-179) in Connected Limited Device Configuration (CLDC). Implementations of this specification may rely on several location methods, including satellite based methods like GPS, as well as short-range positioning methods based on Received Signal Strength (RSS). Though RSS is a good location fingerprint for indoor positioning, no standard technique to tailor RSS-based approaches to the JSR-179 API has been proposed yet. In this paper we propose such a technique, and we evaluate its effectiveness through a Bluetooth-based prototype. Specifically, we show how to extend the Java APIs for Bluetooth (JSR-82) in order to provide the Location API with RSS-based position-information. Moreover, we show how to adapt RSS-based approaches to Location-API's semantics. Our solution is based on the insertion of a specific component into the JSR-82 API. This is in charge of producing all the information needed to build Location objects as defined in the JSR-179. We evaluate the effectiveness of the approach by examining preliminary experimental results obtained from the first system prototype.
