A Java']Java-centric distributed object-based paradigm for surveillance services and visual message exchange

Building an effective surveillance system on the Internet is an interesting application involving the interoperability of heterogeneous computing environments and the challenge of orchestrating the exchange of different visual message types in a unified manner. In this paper, we propose a distributed object-based paradigm to achieve this by applying the so-called bridging technologies for supporting distributed surveillance services. This paradigm integrates emerging technologies of the next-generation Internet-based applications ranging from wireless transmission at the network infrastructure level, to multi-tier, client/server, and RMI/CORBA at the architecture level, and to Java-centric, delegation-based visual user interlaces, and object web based user interfaces at the system design level. The experimental results show that objects in the paradigm can efficiently cross the boundaries of different platforms, operating systems, programming languages, and visual message types. The DSS paradigm establishes a firm basis for supporting a variety of potentially cost-effective applications in a plug-and-play manner. (C) 1999 Academic Press.
