This paper proposes a new Self-Healing scheme based on Cluster Controlled Mobility (SH-CCM) for UWSNs. The proposed SH-CCM scheme uses the idea of mobility within a cluster of sick sensors beside the idea of the hybrid cooperation between both reactive and proactive peers and these sick sensors. This increases the chance of finding health neighbours and as a result it enhances both data security and...
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...
With the advancement of information technology, the wireless network and mobile device continue development, which make people can acquire new knowledge with unlimited time and space. Moreover, learners could interact with people or things in real time to truly experience the learning content and situation. Therefore, learning was no longer limited to classroom and time frame. As long as learners...
There is a need for reliable and trustworthy public transport planner services. Mass transits are trying to solve problems as traffic jams or increasing pollution in densely populated city agglomerations. Passengers are looking for travel information on-line and companies providing public transport solutions often struggle with providing modern trip planner platforms. We address this problem by providing...
Mobile communication has enjoyed a tremendous rise in popularity during the last decade. The network reliability is an important concern in wireless ad-hoc networks. Therefore, it is felt essential to evaluate the reliability of the Mobile Ad-hoc Network (MANET). Many existing wireless ad hoc network routing protocols assume the availability of reliable nodes. This, however, is not a realistic as...
This paper focuses on usage intention of the e-commerce based on ATM model. After empirical analysis, the following conclusions were made: Customer usage attitude has a significant positive impact on customer usage intension; customer perceived usefulness, perceived ease of use and perceived risk would significantly affect usage attitude. At the end, this paper proposes related suggestion about e-commerce.
This paper first briefly introduces the Mobile Agent technology, then analyzes some other Mobile Agent communication mechanisms by comparing them with each other, based on which we generate Assistant Agent by Mobile Agent with combination of Shortest Path First (SPF) algorithm to receive the message as a new Mobile Agent communication system and give the experimental results to demonstrate.
The United States Department of Defense funded a research project at the University of Virginia to increase community resilience after a crisis (e.g., natural disaster, bioterrorism attack). The premise is that the public would be better served if it had access to reliable, near real-time information concerning the "ground truth" (actual observations and pictures) of unfolding events. One...
Using electronic transaction instead of manual ones is an easy way to facilitate business process automation. A cost effective option of introducing electronic transactions in public systems with high number of users is applying contactless cards and the related contactless infrastructure. The spreading of Near Field Communication (NFC) compatible mobile devices made relatively easy the implementation...
As an advanced technology for information sensing and transmission, Internet of Things (IoT) has been applied extensively in the power generation, transmission, substations, distribution, utilization and other processes, and will develop with broad prospect in Smart Grid. This paper focuses on IoT application in transmission lines. A networking strategy for transmission line on-line monitoring system...
The paper presents the idea of Telco 2.0 with an e-health usage scenario. Since numerous elderly people are going missing every year, proposed emergency location service depicts a way in which mobile operators' networks, the Internet and possibilities given by rapid improvement of smart-phones' functionalities can converge in order to relieve the problem. The descriptions are supplemented with sets...
In spite of the advancement and variety of available mobile based applications, there is an eminent need to investigate the current position of the acceptance of those mobile health applications that are tailored towards the patients' medical information management and access. This paper explores and analysis the technology acceptance of the use of smart mobile phones from users' perceptions, viewpoint,...
Trust plays an important role in software usage. It helps users overcome perceptions of uncertainty and risk and engages in trust behaviors. In this position paper, we propose using the trust behavior as a main characteristic to provide software recommendations. We explore a model of trust behavior that contains three root constructs: using behavior, reflection behavior and correlation behavior. The...
Based on Technology Acceptance Model (TAM), this paper is the first one which research consumers' using intention of mobile reading. Multiple regression analysis is used to analyze effects to Chinese consumers' intention and attitudes on using mobile reading by perceived usefulness, perceived ease of use, perceived behavioral control, perceived entertainment, perceived payment and subjective norms...
In this paper, we are looking at the correlations between the short message service (SMS) failure and the brand trust. Furthermore, we hope to find that different kinds of SMS failure may have different effects on brand trust also. Data were gathered using a scenario-based experiment by designed four service failure scenarios. The survey carried out some research aims at the college students (N =...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
