We argue in favor of cooperation among agents and propose a new method to utilize potential field as a tool for estimation of the environment. In our method, potential of environment gives agents some criteria to assess environmental situations from their own perspective. The potential of each object represents its influence on the environment and the environmental potential, i.e., summation of each object's potential, represents global situation of the environment. Agents' decision of their behavior will be done by refining the policy obtained from potential. We use a trash collecting problem as an example to show the effectiveness of our method. Furthermore, we show the efficiency of our method by some sets of experiments of the trash collecting problem. We also discuss the applicability of our method to hybrid systems, environments where available information has a margin of error, or environments where agents' range of vision are limited.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

In particular P2P streaming architectures have attracted attention. Some of them consider many-to-one streaming or high level multicast techniques. In contrast to these models we propose techniques and algorithms for point-to-point streaming in autonomous systems as it might occur in large companies, a campus or even in large hotels. Therefore we introduce the architecture of an overlay network. Each subnetwork contains local active rendezvous server (LARS) which do not just act as directory server but also control availability of movie content in their subnetwork. Due to this we consider data placement strategies depending on restrictions of network bandwidth and peer capabilities as well as the movies's access frequency.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

This is because new services such as video on demand and remote meeting systems require better QoS. However, the problem of QoS routing is difficult and to find a feasible route with two independent path constraints is NP-complete. Also, QoS routing algorithms for broadband networks must be adaptive, flexible, and intelligent for efficient network management. In this paper, we propose a multipurpose optimization method for QoS routing based on genetic algorithm (GA). The simulation results show that proposed method has a good performance and is a promising method for QoS routing.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

Numerical results show that it is important to choose appropriate parameters and compromise the number of voice stations and the data traffic throughput to get the enhanced performance of IEEE 802.11.

An admission control scheme is also considered to further guarantee the QoS of real-time traffic. The area of a cell is divided into non-handoff, pre-handoff, and handoff zones so that bandwidth is reserved in the target/sub-target cell as mobile stations move into the pre-handoff zone and leave the serving base station. The amount of bandwidth to be reserved is dynamically adjusted according to the location, the instantaneous variation of velocity and direction of mobile stations. Two scenarios of the MDPRR scheme are compared by considering the velocity threshold in the calculation of the weight of direction. The results show that employing the velocity threshold in the MDPRR scheme can indeed reduce connection dropping probability, and make better usage of the reserved bandwidth.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.

However, there are some difficulties in implementing virtual space on the mobile computing environment, mainly due to hardware limitations such as computation power, communication capability, and memory size. In this paper, we ease the difficulties of using large-scale virtual space based on the real world (LVBR) in the mobile environment. We have established a scalable and efficient method of constructing and managing LVBR on cellular phones, and have implemented a system named KEITAI-Space. KEITAI-Space is designed to provide the scalable photo-based virtual space to cellular phones that takes into account the hardware limitations. The virtual space is made of a collection of photos and can be edited and expanded by people with cellular phones on hand.","PeriodicalId":186142,"journal":{"name":"18th International Conference on Advanced Information Networking and Applications, 2004.
