The rapid advancement of information technology in today's digital era has made major changes and developments in shopping experience. Shopping online is a new trend of the market today in line with the development of technology. Mobile commerce is a new method of online shopping where purchasers can conduct transactions and direct purchase from a commerce portal through their handset. The purpose...
Lately, mobile device has become a convenient platform for augmented reality (AR). Day by days, mobile devices are getting popular as a platform for AR application such as a Smartphone. Mobile AR (MAR) is mainly available whenever people require an informational support for a focused task. However, only a limited number of researches are avalaible in the mobile augmented reality application. The objective...
Strict Priority Queuing (SPQ) is a widely used queuing method for applying preferential service on edge networks. SPQ, in presence of persistent high priority traffic, is known to behave in a very hostile manner toward low priority flows, causing them to experience poor TCP performance. This often leads to substantial packet losses, which consequently results in aggressive reduction in the congestion...
In this study, a long term mobile learning program was conducted and a survey was developed to explore the effects of mobile learning on five 21st century core competences, that is, collaboration, communication, complex problem-solving, critical thinking and creativity, using a sample of 606 high school students from 10 high schools in Taiwan. Exploratory factor analysis was conducted to show that...
Cellular Data Network measurement and analysis has long been used to characterize Cellular Data Network usage and user behaviors, but with the rapid growing of all kinds of smart terminals and the varied applications on them, the amount of Cellular Data Network data has been growing exponentially. With respect to this challenge, a new management system for the data storage and query has been emerging...
Electronic evidence extracted from a mobile telephone provide a wealth of information about the user. Before a court allows the trier of fact to consider the electronic evidence, the court must ensure that the subject matter, testimony of which is to be given, is scientific. Therefore, regard must, at the investigation stage, be given to fulfill the requirements of science and law, including international...
With the Internet of Things, a new times of mobile machine control will come. Meanwhile,some new problems will come too. Speak ordinarily, a mobile machine control system should have the properties of realtimeness, stability, reliability, and control precision. But in the environment of the Internet of Things, the transmission of wireless signal is unstable, that may affect the performance of a mobile...
The full-scale highway accelerated loading testing facility is an international fashionable and popular equipment of evaluting a commendatory reasonable pavement structure's performance, so a highway accelerated loading testing facility is developed, which has self-owned intellectual property. The mechanical structure and the control system of the highway accelerated loading testing based on CAN bus...
Mobile Web browsing services bring the full PC browsing experience to customer's mobile handsets which have been emerged. This study is to investigate the intention to use mobile Web browsing based on technology acceptance model (TAM) which has been widely used to explain and predict the IT acceptance and incorporated with self-efficacy which was identified as an important determinant of user's new...
Mobile advertising employs mobile devices such ascell phones and PDAs to transmit advertisinginformation to users. The chief difference betweenmobile advertising and traditional advertising is thatmobile advertising must employ wireless networks andmobile devices; as a consequence, apart fromadvertisement content, the factors affecting attitudetowards mobile advertising may also includeconsumers'...
Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
Comparing to wire networks, there are many different characteristics in wireless environments, which make TCP congestion control mechanism is not directly suitable for wireless networks and many improved TCP congestion control mechanisms have been presented. But these improved schemes are not considered the influences to TCP senderpsilas packet sending rate by the wireless link corruption. However,...
This paper deals with the design of a multicarrier multiple-input multiple-output system which performs nonlinear Tomlinson-Harashima precoding at the transmitter and linear equalization at the receiver. The goal is the joint optimization of the processing matrices at both ends of the wireless link, assuming a constraint on the overall transmit power. We consider different design criteria which require...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
