In recent years, the online large-scale services such as transport service system has massively expanded and reached a large number of users. However, while the service providers are striving to best-utilize and efficiently organize their resources, they face a crucial challenge of users' demands which, at many times, contradict the resource utilization. Thus, this paper extends the previous work...
In rapidly changing service provision system, users' requirements and resource movement are constantly changing. To effectively utilize resource and provide the non-stop service to users, autonomous decentralized community system has been proposed. Community is autonomously formed with local majority sharing among same-preference members, and each member cooperate to one another autonomously. Moreover,...
In most of the indoor factory monitoring system sensor relocations and reorganizations are necessary with reorganization of production lines and/or starting of new production lines. These relocations and/or additions sometime make congestion in some area of the network and difficult to achieve online expansion. As a result, in the dynamic changing environment the online expansion is a challenging...
The market and users' requirements have been rapidly changing and diversified. Under these heterogeneous and dynamic situations, not only the system structure itself, but also the accessible information services would be changed constantly. To cope with the continuously changing conditions of service provision and utilization, faded information field (FIF) has been proposed, which is an agent-based...
Location based services (LBS) are expected to play crucial role in future of e-commerce. Although, LBS consider service provision on the basis of location, but don't take into consideration time aspect and user's interests. We propose incorporation of time-awareness and demand-oriented contexts along with location to develop idea of community pervasive services (CPS).To identify appropriate service...
In distributed and ubiquitous computing systems, they have been utilized under the evolving situation where the system structure itself, the composing subsystems, their functions, the accessible information would be changed constantly. With the advances of compression, storage and network technologies, video on demand (VoD) service is becoming more and more popular. However, it is difficult for conventional...
With the advances of compression, storage and network technologies, video on demand (VoD) service is becoming more and more popular. However, it is difficult for conventional systems to meet the continuous and heterogeneous requirements from service providers and users simultaneously. This paper introduces an autonomous decentralized VoD system sustained by mobile agents for information service provision...
Under dynamic and heterogeneous environments, the need for adaptability and rapid response time to information service systems has become increasingly important. In order to cope with the continuously changing conditions of service provision and utilization, faded information field (FIF) has been proposed. In this paper, based on the analysis of the relationship that exists among the users distribution,...
