A NEW SYSTEM ARCHITECTURE FOR PERVASIVE COMPUTING

We present new system architecture, a distributed framework designed to support pervasive computingapplications. We propose a new architecture consisting of a search engine and peripheral clients thataddresses issues in scalability, data sharing, data transformation and inherent platform heterogeneity. Keyfeatures of our application are a type-aware data transport that is capable of extract data, and presentdata through handheld devices (PDA (personal digital assistant), mobiles, etc). Pervasive computing usesweb technology, portable devices, wireless communications and nomadic or ubiquitous computing systems.The web and the simple standard HTTP protocol that it is based on, facilitate this kind of ubiquitousaccess. This can be implemented on a variety of devices - PDAs, laptops, information appliances such asdigital cameras and printers. Mobile users get transparent access to resources outside their currentenvironment. We discuss our system’s architecture and its implementation. Through experimental study,we show reasonable performance and adaptation for our system’s implementation for the mobile devices.
