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(More)
Over the last years, technology evolution is leading the way towards autonomous, ubiquitous and widespread interactions among small computing devices. To this aim, communication technologies that support dynamicity and mobility and work on inexpensive small devices have attracted much attention. The Bluetooth specification particularly fits this idea,(More)
We present an experiment relative to the use of Bluetooth wireless technology to provide network support for midlet applications accessing Web services. We refer to the most common architecture used to invoke Web services, where a client and a server exchange SOAP messages using HTTP as the transport protocol. To the best of our knowledge, there is no(More)
Web Services technology provides software developers with a wide range of tools and models to produce innovative distributed applications. After the initial diffusion of the standard technology the attention of the developers has focused on the ways to secure the information flows between clients and service providers. For this purpose several standards(More)
