We use a football game to evaluate this mechanism. In this football game, users can share a virtual space where they can move around, dribble and shoot. To achieve synchronization among users, a client of the game exchanges data through a server within a certain period time. A problem of such a system is that all users should share the space in the same time for justice competition. But because of the different capacity of computers and the time cost of the communication between clients, it is difficult for all clients to update the virtual space simultaneously. In our systems, we introduce a waiting time synchronization mechanism. To evaluate our proposed architecture and mechanisms, we make a series of experiments in our local area network and then build and analyse the model of our system.","PeriodicalId":215129,"journal":{"name":"Proceedings.

The language is an extension of first-order concurrent dynamic logic (CDL). In this semantics, the expressions of the language are interpreted as actions or state transitions of private viewpoint models (PVM), which are models of environments recognized by a cognitive agent, are based on ecological realism, and are modeled by a metaphor of cameras and camera works. The invariance of truth of motion independent of viewpoints, actions on viewpoint resettings and empathizing with other agents can also be treated with this language and semantics, which give us a formal basis of communications between cognitive agents on recognized contents and how to recognize them.","PeriodicalId":215129,"journal":{"name":"Proceedings.

We investigate JXTASearch, a distributed search engine constructed on Sun's open source P2P platform JXTA, and further extend it to support Dublin Core Metadata Element Set (DCMES) based P2P searches. While the JXTA platform provides essential interoperability among various peers at the \"network\" level, DCMES constitutes the minimal interoperable basis for educational media discovery at the \"metadata\" level. We then discuss the advantages and shortcomings of our prototype implementation, as well as future work building upon our experience with the prototype.","PeriodicalId":215129,"journal":{"name":"Proceedings.

Most office workers use a schedule management system and their schedule data are also shared with other workers for group schedule management. Empirical analyses have taught us that the direct use of schedule data is the key to successful ubiquitous knowledge sharing amongst busy white-collar workers. The authors have been developing \"KM Goodinator (Knowledge Management Group Coordinator)\", a ubiquitous knowledge management tool that runs with commercial schedule management groupware. The tool handles schedule data as a knowledge repository that includes: (1) a human relationship database; (2) a who-knows-what directory; and (3) a scheduling knowledge database. Because the system allows users to use schedule data as knowledge without maintaining the knowledge database, ubiquitous knowledge sharing is easily achieved. Although knowledge retrieval performance is not as good as more integrated knowledge management systems, the easy-to-adopt feature of the approach should be welcomed by busy organizations.","PeriodicalId":215129,"journal":{"name":"Proceedings.

Wireless networks are particularly vulnerable to intrusion, as they operate in open medium, and use cooperative strategies for network communications. By efficiently merging audit data from multiple network sensors, we analyze the entire ad hoc wireless network for intrusions and try to inhibit intrusion attempts. In contrast to many intrusion detection systems designed for wired networks, we implement an efficient and bandwidth-conscious framework that targets intrusion at multiple levels and takes into account the distributed nature of ad hoc wireless network management and decision policies.","PeriodicalId":215129,"journal":{"name":"Proceedings.

The hardware architecture of the Home gateway presented in this paper is based on ISO/IEC JTC I/SC 25/WG 1. The packet processing architecture proposed in this paper takes into account the characteristics of the home network environment so that the packets in the home network are processed very efficiently.

As a result, we can learn a wide range of related knowledge free will. However in existing VOD (Video On Demand) systems, there is no function available to effectively combine and provide texts, pictures and videos, nor can the related knowledge be acquired. Therefore, in this paper in order to make it easy to learn both the video contents and the knowledge related to them, we developed a system to extract related information, such as keywords suitable for the video contents and their related words, and we built an interface to efficiently view those related information and videos. Moreover in consideration of the distributed VOD server we clearly describe the relations between video keywords, their related words through XML/RDF in a standardized, interoperable manner for sharing and combining of information.","PeriodicalId":215129,"journal":{"name":"Proceedings.
