Distributed Computing for Ubiquitous Systems

Distributed computing provides a strong foundation on top of which a powerful ubiquitous system can be realized. However, distributed computing is not solely sufficient for the ubiquitous systems –a completely new era of computer world which is not based on the conventional mainframes or PCs but on the virtually intelligent silent objects/devices used for dayto- day human activities. This article de scribes basics of ubiquitous systems at introductory level and discusses developing a ubiquitous system as an extension to DIICS (Distributed Intelligent Instrument Control System) – a temperature monitor and control system developed by t he author. Moreover, it also discusses significant role of Tini InterNet Interface - a technology used in DIICS, for embedded device support in ubiquitous systems. It also discusses how distributed system fundamentals best fits for ubiquitous systems. Furthermore, it discusses various distributed system goals and specifies how these goals can contribute to ubiquitous systems solely or partially. It also specifies respective changes, and demand for new or adapted architecture/platform, to accommodate it for an efficient ubiquitous system. Towards the end it describes Remote Process Call (RPC) and Event Notification model, two powerful distributed system techniques
