This work explores this standard when providing QoS support to different traffic types. We describe a new bandwidth allocation protocol, which distinguishes among five types of connections, each one of them having its own QoS requirements. We carry out a performance evaluation via simulations that reflects the behavior of the novel MAC protocol. The bandwidth allocation protocol is evaluated in terms of its flexibility and efficiency in supporting delay sensitive traffic. We look particularly to MPEG-4 video communications, an application which is expected to be widely deployed in broadband wireless LANs.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

Routes in such a network may fail frequently because of node mobility or other issues. Stability therefore can be an important element in the design of routing protocols. Stable routes, also called long-lived routes, can be discovered and used to reduce the overhead resulted from route maintenance in ad hoc networks. We propose the long-lived route prediction (LRP) scheme to discover stable routes. The LRP scheme is distributed and predicts long-lived routes based on the history of link lifetime. Furthermore, we apply the LRP scheme to both the open area and urban area using simulation. Simulation results show that the LRP scheme can indeed discover stable routes to reduce route rediscovery, and can be much more efficient and scalable.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

In this paper, we propose a mechanism in the partially ordered user hierarchy, instead of the tree hierarchy discussed till now, by assigning each user an interpolating polynomial constructed from the user's own id number and his fathers'. In this way, any two users' relationship can be quickly determined from evaluating their associated polynomials. Moreover, whenever a new user is added into or deleted from the user hierarchy, none or only some relevant polynomial needs to be updated, different from allover the information needs to be reconstructed as shown in the previously proposed schemes.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

A large number of traditional Japanese fittings in local areas are redesigned as CAD data by three-dimensional computer graphic into and stored in the distributed databases over network where user can interactively retrieve the desired fittings and put those into the traditional Japanese interior to design more creative and original houses, hotels and other buildings in real-time. We initially implemented our prototyped system using JAVA and VRML over Internet environment, but extended it using OpenGL and IRIS performer on the CAVE environment over the high-speed network to improve its reality and response. Now, user can walk through the desired virtual space as a Japanese interior organized by various Japanese traditional fittings and interactively change those fittings by selecting fittings and replacing using \"liquid shutter glasses\" and \"wand\" device by simple operations. As a result, we could verify the usefulness of our suggested system for those people who are concentrating in this crafting industry but also for the people who are ordinal customers of housing.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

Communication latency can not be effectively hidden without considering the data delivery sequence for a task. In this paper, strategies for achieving high performance incremental computing on a network environment are studied. It has been proved, in this paper, that the performance of an incremental computing is strongly related to the strategies of organizing the data delivery sequence. Simulation of matrix multiplication is also conducted to illustrate the effects of various strategies and the results are given and compared.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

Service providers and operators must follow this evolution to address customers' expectations. With customers' changeable behaviors, a platform must review its architecture and adapt itself to reduce time-to-market of new services and satisfy all demands. In this context, solutions are about auto-adaptation and reconfiguration. These two operations should take place dynamically and rapidly, with no damage to platform functions. They also have to fulfill other features such as security, real time applications, error tolerance, etc. Our aim is to give an architecture which can support the reconfiguration process. We also expose some situations and scenarios to prove that bad situations (low throughput, call drop, bad QoS, etc.) are improved with reconfiguration.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

In information retrieval, network and distributed system management, and electronic commerce, a mobile agent is more flexible than the traditional communication paradigm. Despite the performance benefits, a mobile agent is not used widely in the market because it is very vulnerable to a variety of attacks. In many studies related the security vulnerability for a mobile agent, the high security causes the performance to degrade. In this paper, we propose and evaluate an efficient security model for a mobile agent using TDGM (trusted domain and guide manager), which provides three kinds of services: the trusted domain management, the security service and the travel plan guide. The result of our experiments clearly shows that this model provides high security and mitigates the performance degradation.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.
