With the popularization of today’s mobile devices, the environment that enables us to publish and utilize information independent of location and time has been actualized. In the future, various kinds of sensors such as GPS as well as network-enabled appliances will also be connected to the Internet. By utilizing various kinds of information acquired(More)
To reduce the user-perceived latency in web content delivery, many techniques have been proposed. One is a transmission time control mechanism that automatically adjusts the quality of inline objects, such as images on a web page, according to the client network bandwidth. Another is a transmission order control mechanism that can transmit inline objects in(More)
In the ubiquitous computing environment, we believe that P2P-based context-aware application utilizing sensing data is important. However, since sensors are not placed under the control of one specific entity, it is difficult to retrieve appropriate information from the distributed sensors. In addition, when the same queries are sent by different users,(More)
This article presents a Web content adaptation and delivery mechanism based on application-level quality of service (QoS) policies. To realize effective Web content delivery for users, two kinds of application-level QoS policies, transmission time and transmission order of inline objects, are introduced. Next, we define a language to specify these policies.(More)
Today, billions of users use the Internet to access various multimedia information on the World Wide Web (WWW). Most users, however, are given low-speed connection to the Internet and are often irritated by long transmission time of WWW pages. Therefore, it is very important for information providers to tailor the presentation of information to users’(More)
In broadband networks such as ArM (Asynchronous Transfer Mode) networks, the dynamic migration of data resources, such as databases and files, has become more powerful and effective than that in conventional networks so far. In environments with migratory data resources, it is necessary to develop a method to manage the location of each resource. In this(More)
