diligent Distributed Information system of rules Fundamentals and Architecture of Mobile Distributed Information System Q1. What is a mobile distributed culture system? Answer. In todays mobile society, introduction to relevant information and to context-specific service anytime, anywhere is suitable increasingly important. This is the surround for our research, development and consulting activities in selected current topics of Mobile Distributed Information Systems. Mobile users argon often particularly interested in information about and work in their immediate vicinity, thus Mobile Distributed Information Systems must speech communication localization of function-dependent distribution of and access to services and information from mobile devices. The users topological and geographical location becomes relevant for the semantics of communication, and such communication has to remain seamless even in foreign environments, with little or no need for manual reconfigurati on. Frequently, in addition to his location, the users current situation determines his information and service requirements. With mobile devices becoming more and more powerful, mobile users themselves may offer information and services to peers in an improvised manner. As a result, the long-established distinction between clients and servers is blurred, which calls for an character of the architecture prototype towards peer and/or alternating roles. (Reference from http//www.wkap.nl/ grok/b/0-7923-9697-9) Recent years have witnessed a rapid proliferation of mobile information devices. Cellular phones have become not only a canonic means of communication for many people, but have also genuine from simple telephones suitable only for voice communications into computing devices equal to(p) of t... .../Preference Profiles (CC/PP) profile can be used to provide a description of mobile device. Different MSS are in different different network and these MSS need to cooperate and co mmunicate with each other for exchanging data. A standard interface is needed between MSS. Java technologies or a middleware like CORBA can be used to solve the heterogeneous problems.
