But what is the optimum distance for distance-based location management? Does it depend on cell-size, and/or the movement behavior of an individual user, depending on her movement pattern, more efficient? Or should a simple fixed distance for all users be adopted? We have shown that a fixed distance of 4 is nearly optimum for all the mobile hosts, irrespective of a range of variation of their mobility behavior, and the cell size of the network. A more efficient adaptive distance algorithm, where distance is changed according to mobility behavior, is proposed.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

In order to fulfil the ubiquity requirement for service, PCS rely on two main features: use of wireless communications technology and mobility management. The former sets the basis to untie subscribers from a wire allowing them to freely move around. The latter allows subscribers to gain access to the network services at all times regardless of their location. A handover is the process used to allow a call in progress to continue as the associated subscriber moves around. A large number of handover mechanisms have been reported in the literature. In this article, we carry out a comprehensive performance study of the handover mechanisms as proposed in the literature. A detailed simulation model has been developed allowing us to set up parameters such as the speed and motion path of the mobile terminal. The performance metrics of interest are: the length of the disruption time caused by the handover mechanism and the number of lost packets caused by the handover mechanism. Under the scenario under consideration, the handovers using multicasting mechanism and full reestablishment mechanism exhibit the best results.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

This approach employs preemptive resume scheduling mechanism which reduces queuing delays involved in the processing of mobile transactions at each network node. Such reduction of queuing delay significantly improves performance of mobile transactions given the heavy network traffic and the lower network bandwidth. We have conducted several experiments using analytical modelling approach in order to determine the impact of priority scheduling mechanism on the performance of mobile transactions. Experiments show significant performance improvements of the proposed approach over existing approaches of mobile transactions. It has also been shown that the proposed approach is robust in that it can be applied to improve the performance of current mobile transaction approaches.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

Media transcoding functions are useful for intercommunication on heterogeneous computer networks. However, it is difficult for us to prepare the suitable transcoding node in advance because the required intercommunication environments are not always static. Accordingly, we should consider dynamic transcoding functions with relocatable decision methods. In this paper we propose a novel middleware system that realizes dynamic transcoding functions by extended media stream.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

But the personalized learning support is limited in most researches, because the human cognitive processes and educational psychology-based study method are not considered. Our previous work proposed a learning support system based on a study method known as SQ3R. The system provided a set of tools and a simple navigation function following the SQ3R. But the navigation in this system is not flexible enough to follow the substance of the SQ3R. In order to support and promote learners to learn as the SQ3R scheduled, in this paper, we give three types of navigations named as heuristic tool-using navigation, traffic-light progress navigation, and suggestive review navigation.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

One of the major issues in the network society is how to bring people together, that is how to form the communities that share similar interests. The formation of communities brings a great deal of benefits to the members such as social collaboration on the Internet, recommendations from people who are interested in similar topics, etc. However, acquiring information about communities and selecting appropriate communities to join is a burden for most of the people and the burden restricts their lives in the network society. We propose a model of community formation with multi-agents with consideration of the cognitive balance model of the user. Personal agents can help the users by gathering and exchanging information, and recommending or assisting the users in making choices. The proposed model is evaluated through experiments.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

It provides four special features in comparison with other version management systems: higher system reliability and robustness, effective revision collision prevention using proactive agents, context-aware environment for team software revision, a unified XML format for configuration and history files as well as system and agent exchange messages. Every peer holds a shared space synchronized with other peers' ones, and a workspace for a user's ordinary editing. GRAM is implemented using the JXTA technology that consists of the virtual JXTA network and basic peer group services. The system GUI and basic functions in the current prototype are also presented to show its basic usages. By using GRAM, version management of various software development projects can be comfortably conducted.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.
