Drive-thru Internet has become a popular solution vehicular Internet access. However, the quality-of-service provisioning for high-data-rate drive-thru Internet services poses significant challenges upon medium access control (MAC) in a large-scale and highly dynamic vehicular environment. In this paper, to achieve high throughput in drive-thru Internet, we exploit the mobility interdependency between...
In this paper, we consider a DTN/WLAN integrated network where high-mobility nomadic nodes form a delay tolerant network (DTN) and low-mobility local nodes reside in the coverage area of wireless local area networks (WLANs). A data dissemination service facilitated by packet pre-downloading is generated by a server in the Internet and destined to a group of nomadic nodes. In order to achieve efficient...
In this paper, we consider a DTN/WLAN integrated network where nomadic nodes with high mobility comprise a delay tolerant network (DTN) while local nodes with low mobility reside in the coverage area of wireless local area networks (WLANs). A message dissemination service is considered, where data traffic is generated by a server in the Internet and destined to a group of nomadic nodes. In order to...
The Puppet King website includes a large number of digital video and audio materials of Taiwan's traditional puppet shows. These digital materials include pictures, videos,music and a digital right management system, which protects those materials from been infringed. This system can effectively protect digital contents using the Role-based Access Control mechanism, which controls the users' requests...
In this paper, we consider a wireless communication network for both low-speed mobile nodes in densely populated hotspots and high-speed mobile nodes roaming in a large area. Wireless local area networks (WLANs) are deployed in the hotspots, while a delay/disruption tolerant network (DTN) provides services to roaming nodes in the large area with low node density. We investigate radio resource allocation...
Information fusion is an interdisciplinary research field aiming to combine and merge the information or data from different information sources. The output of information fusion system is a global schema through which users can get information or data from different dispersed sources. To generate a deep Web information fusion system is facing many challenges, because the nature of Web is different...
The Web has been dramatically deepened by the deep Web, which the traditional information fusion system shows disability to integrate. The myriad information hidden behind the deep Web attracts the considerable attention from the researchers. The key element in a deep Web information fusion system is the data source modeling problem, which determine the whole technical method of the whole system....
The Web has become the largest information source, which includes all aspect of human's life. The myriad information is believed to be hidden behind the deep Web, which the search engines and crawlers can't access directly. To extend the human's physical limitation of accessing information, the information fusion system is introduced. The Web is very different from the traditional database community,...
There is myriad high quality information in the Deep Web and the feasible method to access the Deep Web is through the query interface of the Deep Web. Itpsilas necessary to extract abundant attributes and semantic relation description from the query interface. Automatic extracting attributes from the query interface and automatically translating a query is a solvable way for addressing the current...
The e-commerce information on the surface Web is supported by the Deep Web, which can not be accessed directly by the search engines or the Web crawlers. The only way to access the backend database is through query interface. Extracting valid attributes from the query forms and automatic translating the source query into a target query is a solvable way for addressing the current limitations in accessing...
