This paper describes a theoretical framework for rate allocation to maximize the power efficiency of overall heterogeneous wireless networks whose users are assumed to have multihoming capabilities. Therefore, the paper first presents a power consumption model considering the circuit power and radio transmission power of each wireless network. Using this… (More)
The Smart u-Learning System is designed to provide an interactive and social learning environment that accommodates emerging devices. This demonstration will show how teachers and students can use its interactivity and social features in live lecture situations.
Recently, as the number of smart devices increases, the way of digital broadcast contents is changed. This change leads that conventional broadcast media acceptsWeb platform and its services to provide more quality contents. Based on this change, in education field, education broadcasting also follows the trend. The traditional education broadcasting… (More)
Under the concept of Web-of-Object (WoO), emergency service is one of the key components in smart home care. Most distinctive characteristics of the emergency service are prompt detection, confidential decision making, and immediate reaction. For that, besides the general service management, the sensor data management, context processing, and communication… (More)
This paper proposes a video audience measurement framework for MPEG-DASH. In current untrustworthy over-the-top (OTT) environments, the proposed framework utilizes segment-hashing to collect and offer video audience measurement to third party organizations while ensuring the protection of consumers' privacy. The system generates hash values for video… (More)
The number of wireless access points (APs) have increased rapidly in recent years to support increasing demands of wireless local area network. However, some of the research findings show that many of these APs are actually idle mainly during off-peak hours, i.e., there is no active user to support within their coverage areas during that time. Nevertheless,… (More)
Browser-based Web content sharing system is designed for users to share and distribute what they're watching Web contents to other users or system via Web browser. The demonstration will show the novel method to distribute partial Web contents on browsers to other screens in Web browsing environment, especially for e-learning situations.
With the growth of sharing economy, P2P resource sharing services are combined with social networks for improving user experience and giving more trustworthiness to users. For trust management, many P2P resource sharing services adopt feedback-based reputation system. Since peers in services have their social relationship in the community, reputation… (More)
