In this paper QoS control of a real-time multimedia communication system under heterogeneous environments of wired and wireless networks is proposed. In our suggested system, as channel coding the FEC (forward error correction) method with Reed-Solomon coding is introduced to reduce the packet error rate on the wireless network. On the other hand, as source coding, transcoding methods including transformation of various video codings such as M-JPEG, MPEG and Quicktime, control of Q-factor within a frame, frame rate and color depth are introduced to maintain the required QoS, particularly the end-to-end throughput. The increases of the required bandwidth by redundant packet addition with FEC can be suppressed by the transcoding functions while the packet error rate is reduced to the accepted value. In order to verify the functionality and the efficiency in our suggested system, numerical simulation was carried out. As a result, our suggested system by combination of transcoding and FEC could correct the packet error rate with an order of 10/sup 9/ while maintaining the frame rate and the amount of data transform constant.

Time-driven key sequencing (TKS) is a key management technique that synchronizes the session key used by a set of communicating principals based on time of day. This relatively low cost method of session key synchronization has been used in specialized distributed systems with low-end communicating devices where sessions are sparse and each session spans a short time period comprising a small number of messages. In this paper, we describe how TKS may be useful in several scenarios involving high speed computer networks. More importantly, we present a performance model of TKS and conduct a detailed analysis to determine the impact of clock drift and network latency on the required key refresh rate. We give the exact conditions for determining the range of adequate key refresh rates, and demonstrate that the derived conditions are sufficient to ensure that data are both protected and deliverable. Interestingly, these conditions may be used to obtain a key refresh rate that can tolerate a maximum amount of clock drift after other parameters in the system are fixed.

Introduces a prototype of wearable healthcare support system 'LifeMinder', which consists of a wristwatch-shaped wearable sensor module and a personal digital assistant (PDA). The wearable sensor module, equipped with sensors of accelerometer, pulse meter thermometer galvanic skin reflex (GSR) electrodes and Bluetooth module to communicate with the PDA, monitors the user context: health conditions, movements and behaviors. The system uses this information to guide the user in daily self-care in real time. Diet care and exercise care are especially significant to prevent the "lifestyle-related disease". The authors developed algorithms to recognize the user movement from wrist motion and to detect the beginning of a meal from pulse rates and GSR values. The accuracy of both algorithms is about 90%.

In the last decade, bureaucratic organizational hierarchies increasingly have been replaced with flatter organizational forms, bringing together people from different disciplines to form project teams within and between organizations. Distributed project teams often are self-configuring networks of mobile and "fixed" people, devices, and applications. They are the natural next step in the evolution of distributed computing, after client-server, Web-based, and peer-to-peer computing. A newly emerging requirement is to facilitate not just mobility of content (i.e. to support a multitude of devices and connectivity modes) to project members, but also mobility of context (i.e. to provide traceable and continuous support of relationships between people, artifacts, and business processes). The contribution of this paper is to present the design goals, the architecture, and implementation of a system aiming at supporting mobility of context for project teams, enabling traceable and continuous support of associations (relationships) between people, artifacts, and business processes.

Event-based communication models provide interesting properties for distributed systems such as asynchronism and type-based selection mechanisms. The Comet middleware we developed proposes such an event-based communication model as foundation. From this canonical model, we show how to build more conventional bidirectional and synchronous interactions with extended features such as implicit type-based multicast or asynchronous operationalization. Furthermore, we demonstrate the use of the lower-level asynchronous model to develop highly flexible distributed services. We illustrate this idea with a publish/subscribe protocol that can be dynamically reconfigured to match various requirements: type-based or content-based filtering semantics, peer-to-peer or mediator-based configurations.

This paper deals with the interaction of all IP mobile Internet devices with networked appliances in a residential home. Two novel mechanisms are described and demonstrated: pointing as an indication of user interest, and user interface loading from the home appliance to a mobile Internet device. The user pointing action is used as a source to both collecting the context information of the user, and triggering the execution of the user interface loading procedure. The provided mechanisms are described in the form of a use scenario, and implemented using a session initiation protocol (SIP) and an open service gateway (OSGi) platform.

As more software is being developed and distributed via the Internet, the number of accesses to file servers, such as FTP servers or WWW servers, is increasing. To reduce concentrated access to the original file server, mirror servers which have the same directories and files as the original server stores have been introduced. However, inconsistency among mirror servers and the original server is often observed because of transfer latency, traffic congestion on the network, and management policy of the mirror servers. Hence, we develop an intermediate FTP proxy server system PFTPD (Proxy FTP Daemon) which guarantees the freshness of files as well as dispersal of the access concentrated on the original FTP server. We found that the proposed system can disperse accesses to the mirror servers with a little overhead. This technology can assure that files are the latest version and adapt to heterogeneous network environments such as the Internet.

We earlier proposed a flexible multimedia system (FMS) that is able to guarantee end-to-end QoS according to priority of parameters and consensus policy. On interconnected computer networks, we can communicate with each other using real-time media such as audio and video by distributed multimedia system that can integrate various realtime and discrete media data. The multimedia system is required to realize end-to-end quality of service (QoS) guarantee functions. When users communicate with each other on interconnected different bandwidth networks, if the system can use translator or mixer functions that are defined by RTP it will be able to guarantee more flexible QoS. In addition, the system is able to organize various multimedia services dynamically. The FMS is a mobile agent based system, therefore the system will be able to organize a translator or mixer dynamically. In this paper we discuss QoS guarantee functions using mobile agent and re-design our prototype system to use mobile transcoding functions for flexible multimedia communication.
我们提出了一种灵活的多媒体系统(FMS),它能够根据参数的优先级和一致性策略来保证端到端的QoS。在相互连接的计算机网络上,通过分布式多媒体系统集成各种实时和离散的媒体数据,我们可以利用音频和视频等实时媒体相互通信。多媒体系统需要实现端到端的QoS (quality of service)保障功能。当用户在相互连接的不同带宽网络上进行通信时,如果系统可以使用RTP定义的translator或mixer功能,则可以保证更灵活的QoS。此外,该系统还能动态组织各种多媒体服务。FMS是一个基于移动代理的系统,因此该系统将能够动态地组织翻译器或混音器。本文讨论了基于移动代理的QoS保证功能,并重新设计了原型系统,利用移动转码功能实现灵活的多媒体通信。

One of the problems faced by large, global organizations and enterprises is to effectively enable their employees to collaborate across locations. People need collaborative work support while they are on the move and have to share business documents and know-how. Although much work has been done in the area of computer supported collaborative work (CSCW) to date, supporting mobility is only recently receiving attention. Hence, most of the existing approaches do not deal with emerging mobile teamwork requirements such as locating business documents and expertise through distributed searches, advanced subscription and notification, community building, and mobile information sharing and access. Furthermore, existing applications and approaches are usually difficult to customize to business-specific processes and requirements. The Mobile Teamwork Infrastructure for Organizations Networking (MOTION) system addresses these requirements and provides a generic teamwork services application programming interface (API), TWSAPI, that can be used to build organization-specific collaborative applications. In this paper we give an overview of the MOTION TWSAPI and illustrate its usage in building an application that provides document review support.
