We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment.(More)
A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, downsized embedded devices monitor and manage the physical process. Mobile Internet Device (MID), as a portable handheld device designed for mobility providing a down-graded computing capability, can be used as a strong candidate for client-side devices(More)
Dynamic composition is a key feature of service-oriented computing (SOC) where services are discovered and composed at runtime. Current standards and methods for service compositions require statically binding published WSDL interfaces into compositions in BPEL. In this paper, we present our early result of a framework for dynamic composition on enterprise(More)
In service-oriented computing (SOC), services are designed not just for a dedicated client, but for a family of potential clients who typically discover and compose services dynamically. For services to be generic and hence serviceable to different users in a given domain, the service variability among different clients must be analyzed and modeled into(More)
Software architecture is known as an effective solution to realize extra-functional and quality requirements. It becomes even more important in developing efficient mobile applications since the resource limitation drawback of mobile devices can be remedied with architecture design. A general guideline is to place heavy-weight functionality on server sides,(More)
