Mobile devices should allow users to exploit services anytime, without any place restriction and in a transparent way. The Bluetooth technology achieves this feature, by providing services at a low cost and with a low power consumption. In a few years, most of the devices accessing the web services will be mobile. In this paper, we evaluate performance of a framework allowing a Java application programmer to directly interface Web Services from a mobile device using a Bluetooth connection. Our work focuses on enhancing Web Services’ range of action, presenting a proof of concept of how Web Services-based application can use Bluetooth technology as communication channel. Furthermore, our work is also dedicated to allow the framework to use all the different settings and connection modalities provided by Bluetooth technology. This paper evaluates the usability and efficiency of the framework in a real scenario using mobile devices with limited resources. Categories and Subject Descri...
