The ever-increasing mobile traffic has inspired deployment of capacity and performance enhancing network services within mobile networks. Owing to recent advances in network function virtualization, such network services can be flexibly and cost-efficiently deployed in the mobile network as software components, avoiding the need for costly hardware deployment. Nevertheless, this complicates network...
In the next decades, hundreds of autonomous ships (AS) and Conventional ships (CS) will cross the Detroit of Gibraltar. For their autonomous operation, and remote control, these ships need to communicate with each other, with the vessel traffic system (VTS), with the port state control (PSC) and with the shore control centre (SCC). For a sustainable maritime industry, the biggest challenge will be...
Modern software systems provide many configuration options which significantly influence their non-functional properties. To understand and predict the effect of configuration options, several sampling and learning strategies have been proposed, albeit often with significant cost to cover the highly dimensional configuration space. Recently, transfer learning has been applied to reduce the effort...
In distributed Smart Farming applications, a reliable communication is often crucial, in particular during collaborating operations. In rural areas, the network connectivity via Public Land Mobile Networks is, however, not always sufficient. Network disruptions may occur hindering reliable transmissions. For the delivery of periodic sensor data streams of agricultural machines, several modern communication...
Mobile learning has emerged as a new and promising learning modality, providing more interactivity and flexibility to learners, tutors and teachers in carrying out educational activities and practices. However, in spite of the benefits, the existing applications still have several issues and challenges to be addressed, such as the quality evaluation of the resulting mobile learning applications. Aiming...
Recently, mobile cloud computing (MCC) is drawing substantial attention due to potential reduction on local energy consumption and local execution time. To further satisfy the requirement of latency-intensive applications in the future, fog computing is proposed to take full advantages of close-by nodes with available resources, thus decreasing the transmission time during computation offloading....
Mobile money is an upshot of the conventional banking system that creates an opportunity for the financially excluded group of people. It allows the unbanked in the rural areas and the underbanked in the urban centers to have access to financial services. User experience is all encompassing as it affects the emotion and the attitude of the user of a product or services. This study reviewed the related...
Mobile communication has become an important part of our daily lives for voice communication and data sharing and access over the Internet. Mobile communication is an open network, so maintaining the privacy and reliability of data has always been anxiety. The reliability of the data against channel noise can be achieved by various error correction codes. The purpose of the channel coding process...
Local databases have become an important component within mobile applications. Developers use local databases to provide mobile users with a responsive and secure service for data storage and access. However, using local databases comes with a cost. Studies have shown that they are one of the most energy consuming components on mobile devices and misuseof their APIs can lead to performance and security...
The purpose of this study was to explore the important factors that influence users’ continuance usage behavior toward mobile online group-buying. Based on the characteristics of the mobile Internet, an extension of the UTAUT model is introduced to verify the proposed hypotheses. The structural equation modeling method is used to analyze the empirical data which come from universities in China. The...
Today's integration of mobile technologies and traditional cloud computing exploits the abundant computation and storage resources in the cloud, to enhance the capabilities of end-user mobile devices. The designs that rely on remote cloud services, however, sometimes overlook the abundant resources (e.g., storage, communication, and computation) on mobile devices. In particular, when the remote cloud...
Mobile phones provide an excellent opportunity for building context-aware applications. In particular, location-based services are important context-aware services that are more and more used for enforcing security policies, for supporting indoor room navigation, and for providing personalized assistance. However, a major problem still remains unaddressed--the lack of solutions that work across buildings...
This article discusses some of the important structures of the area covered by cellular communications; the following concepts are introduced: achievable, useful coverage and efficiency of use of the reception base station coverage area (BS); the proposed formula for calculating the area of coverage. The aim of the article is to determine the most effective structure of the coverage area of mobile...
Because of the characteristics of the availability and practicability, mobile media technology had got a rapid development in the whole world. So, people now often use mobile devices through a mobile application (APP). Based on this, this study established a mobile application customer engagement model to carry on the investigation and research about mobile application of customers' recommendation...
Creative user of mobile health information (mHealth) has the potential to reduce the cost of healthcare and improve health research and outcomes. The objective of this study is to provide a systematic analysis method of selecting the best app through assessment of the user's needs. Specifically, we explain the method through applying it to dysmenorrhea, as this is the most common menstrual complaint...
E-government is an important tool for public sector transformation. The number of e-services available on government websites continues to grow by leaps and bounds. The usage of mobile technologies in the public administration not only provides an alternative communication and services channel for citizens, but also allows to go further. M-government is emerging as the next big wave for ICT use in...
Breast cancer is the most common cancer in women both in developed and developing countries. More than half of all cancer mobile application concern breast cancer. Gamification is widely used in mobile software applications created for health-related services. Current prevalence of gamification in breast cancer apps is unknown and detection must be manually performed. The purpose of this study is...
In cognitive radio networks (CRNs), spectrum sensing data falsification (SSDF) is one of the most typical attack which hugely degrades the detection performance of cooperative spectrum sensing (CSS). SSDF and defense strategies have been an active field of research, but countermeasures of existing researches are sensitive to the number of malicious users (MUs). In this paper, we propose a two-stage...
The recent advancements in mobile network technologies and terminals have enabled ubiquitous Internet coverage, opening novel possibilities for public safety applications, and especially public warning and alerting. In this paper, we present the most recent results of the Austrian national project PASA (Public Warning and Alert System for Austria), the aim of which is to design, prototypically develop...
The paper reported a field survey that sought to examine the technical implications in the adoption of a Global System for Mobile communication GSM-based metering system in the New Juaben Municipality. Both simple random sampling and interview guide methods were used. The issues considered under the study were; understanding of a GSM-based metre reading, mobile phone penetration among consumers, reliability...
