In this paper, we propose a middleware framework that unifies access to GSM-enabled sensor devices in a global computing environment. Typically, communication with mobile sensors relies on proprietary protocols, involving the exchange of SMS and MMS messages. In the proposed framework, we use XML-based control descriptions that abstractly specify these protocols to generate proxies and corresponding WEBbased (HTML, WAP and WEB services) interfaces that realize them. Thus, we provide access

... parency over different kinds of mobile sensors. Besides the overall architecture of the proposed framework, we discuss a particular instance where a GSM-enabled camera with temperature, and motion detection sensors is incorporated into our global computing environment. Finally, we assess the performance of the proposed framework by presenting experimental results. ISSNIP 2005 0-7803-9399-6/05/$20.00  2005 IEEE
