In this paper, we propose a simulator for facilitating reliable and inexpensive development of ubiquitous applications where each application software controls a lot of information appliances based on the state of external ...
In this paper, we propose a framework named ``UbiREMOTE'' for controlling information appliances connected to a home network with a unified and intuitive user interface from a remote place.The UbiREMOTE framework provides ...
In this paper, we propose a method to deliver video for multiple wireless mobile users with different quality requirements. In the proposed method, we assume several proxies and wireless access points in the network. There ...
Estimation of the qualities of overlay links is useful for optimizing overlay networks on the Internet. Existing estimation methods requires sending large quantities of probe packets between two nodes, and the software for ...
Exploration efficiency of GAs largely depends on parameter values. But, it is hard to manually adjust these values. To cope with this problem, several adaptive GAs which automatically adjust parameters have been proposed. ...
In this paper, we propose a method for video ads dissemination through a hybrid network consisting of WiFi and cellular networks, in order to provide timely delivery of video ads with preferred content to users according ...
This paper presents a cost-efficient video multicast method for live video streaming to heterogeneous mobile terminals over a content delivery network (CDN), where CDN consists of a video server, several proxies with ...
In this paper, we propose a new video delivery method called MTcast (Multiple Transcode based video multicast) which achieves efficient simultaneous video delivery to multiple users with different quality requirements by ...
In this paper, we propose a framework which allows remote users to form conversation groups based on spatial relationship in a shared virtual space. Our proposed framework can transport awareness information of real world ...
Finding a vacant parking space in a large crowded parking facility takes long time. In this paper, we propose a navigation method that minimizes the parking time based on collected real-time positional information of cars. ...
Serious traffic congestion is a major social problem in large cities. Inefficient setting of traffic signal cycles, especially, is one of the main causes of congestion. Green Wave is a method for controlling traffic signals ...
In this paper, the authors propose a technique to flexibly implement genetic algorithms (GAs) for various problems on FPGAs. For the purpose, the authors propose a common architecture for GA. The proposed architecture ...
For accident prevention at intersections, it is useful for drivers to grasp the position of vehicles in blind spots. This can be achieved without infrastructure if some vehicles passing near the intersection capture and ...
Recently, context-aware computing with information appliances is the topic of many research efforts. In order to realize context-aware systems, it is necessary to describe rules, each of which consists of (1) transition ...
In this paper, we propose a new method utilizing mobile sensor nodes to prolong WSN lifetime while maintaining a large sensing area. We formulate this problem as a problem in finding the best positions for mobile sensor ...
Watching high quality videos anytime, anywhere is expected because mobile devices become popular. However, if mobile devices try to watch a video at the same time via a wireless network, the concentrated loads to delivery ...
In order to allow every user to extract aggregated computational power from idle PCs in the Internet, we propose a distributed architecture to achieve a market based resource sharing among users. The advantages of our ...
The triage tag is used in Mass Casualty Incident (MCI) to check the priority of patients treatments and conditions. However, it is difficult to grasp a change in the patient's information since it is a paper tag. In this ...
We propose a QoS adaptation method for streaming video playback for portable computing devices where the playback quality of each video fragment is automatically adjusted from the remaining battery amount, desirable playback ...
We propose an energy-aware video streaming system for portable computing devices, in which the video can be played back for the specified duration within the remaining battery amount. To save power, we introduce techniques ...
