In the past decade, with the rapid development of wireless communication and sensor technology, ubiquitous smartphones equipped with increasingly rich sensors have more powerful computing and sensing abilities. Thus, mobile crowdsensing has received extensive attentions from both industry and academia. Recently, plenty of mobile crowdsensing applications come forth, such as indoor positioning, environment...
As mobile computing platforms, head-mounted displays (HMDs) for augmented reality (AR) applications, similar to other mobile computing platforms, face challenges in minimizing their energy usage. While not yet as pervasive as smartphones, we can envision that more useful everyday AR applications can arise as we allow HMDs to enjoy longer operation times. This work takes a first step in designing an...
Learning about herb is important for daily medical treatment. People should know how to use herb around them to cure simple diseases in daily life. This reason inspires us to create the herb database application to be used as standard for research and study in the future. We hope that this application will provide knowledge and benefit to every group of people such as instructors, students, doctors,...
Multi-vehicle operations using various types of unmanned vehicles (UVs) can increase efficiency of marine data acquisition, reduce the crew risk and lower mission costs. These types of missions are very complex and often involve systems that are not interoperable. From an operational perspective however, some level of integration is necessary. Typically, a common network system architecture and Situation...
Requirements of mobile apps are often hard to elicit from massive numbers of users, although it is important for the solution architecture to meet them. Mobile Twin Peaks approach is proposed as a process of developing apps concurrently and iteratively that incorporates bidirectional communications within a mobile app. The communications allow both requirements engineers and software architects to...
The need for performance and energy efficiency in mobile devices is apparent with the obvious shifting of more intensive computation to mobile platforms. In this paper, we first make a clear distinction between performance and energy issues. Apart from showing that performance efficiency is neither co-related with energy-efficiency nor inefficiency, we focus on programming methodologies and software...
Among the important benefits of mobile applications are portability and accessibility. Integrating a native mobile application with a Web portal increases the value and quality of the final system. A developer perspective is presented in this paper discussing about the main motivational factors and decision criteria in the selection of the most appropriate mobile ecosystem. Also the main software...
Cloud radio access network (C-RAN) centralizes several baseband units to form a pool, which is the primary form of the wireless network virtualization. Some aspects of C-RAN are always developing, such as the processing capacity and multiple radio access technology (multi-RAT) convergence. In this paper, the Not Only Stack (NO Stack) framework, as a virtualization approach, is suggested to be employed...
In the LTE EPC, many network entities and interfaces have to be maintained and updated regularly. Moreover, to accommodate more users, new hardware must be integrated, although rarely used. To address these challenges, the EPC can be moved to the cloud using two modern technologies: SDN and NFV. In this paper, we study the impact of integrating these novel technologies on LTE networks. We propose...
The most recent trends in the electronic commerce research have suggested that forming an ecosystem around a platform would create a winning solution. The ecosystem, consisting of vendors and external actors, would create competitive advantage for the platform owner. Furthermore, the sheer number of the actors has been used as the measure of the ecosystem's well-being against competing ecosystems...
Nowadays, the need to tackle rapidly increased crimes is increasing day by day to help ensuring justice. Digital forensics can be defined as the process of collecting, examining, analyzing and reporting of digital evidence without any damage. Digital forensics requires a detailed examination of devices such as computers, mobile phones, sim cards, tablets that contain digital evidence regardless of...
We conducted a qualitative study to investigate the main aspects related to the development and management of applications (or apps) for smart and mobile devices. Is investigation is composed of two main steps and its context is the so ware industry. In the rst step, we interviewed so ware managers with experience in the context of app development and management. Is part of our study can be intended...
In this work, we report a study carried out to identify a set of metrics to early estimate the development effort of mobile apps. The applied methodology was inspired by the work of Mendes et al. who addressed a similar problem in the field of web apps. In particular, we extracted an initial set of metrics by analyzing the online quotes forms that companies made available on their websites. Afterward,...
App store reviews are currently the main source of information for analyzing different aspects of app development and evolution. However, app users' feedback do not only occur on the app store. In fact, a large quantity of posts about apps are made daily on social media. In this paper, we study how Twitter can provide complementary information to support mobile app development. By analysing a total...
With the development of globalization intensified, China's social and economic level continues to improve, cultural exchanges are also showing more and more prosperous scene. In this context, China's digital media industry is also the rapid development, especially in recent years, mobile phone technology constantly updated, the emergence of new media, have greatly promoted the mobile media industry...
Seating position in university lectures is commonly linked with student grade performance. Sitting at the front of lecture theatre is generally reported to have a positive effect on final grade. This study investigates and analyses the seating positions, course engagement, prior programming experiences and academic abilities of students throughout a 12 week Java programming university programme and...
Developing for devices like smartphones, tablets or smartwatches is more than just "shipping code". Especially in mobile development there is a strong focus on user interface design and user experience. In order to explore the design space, development teams and designers need early feedback from users testing the designs. Continuous Delivery (CD) is a well-established technique for the...
Software startups can be subject to extreme money and time constraints while hoping for delivering reliable software. In a harsh startup environment, software may face quality downgrade either by improper process management or incapable human resources. Among the many, security is a fragile software quality characteristic responsible for severe negative consequences such as jeopardizing a startup's...
Mobile app testing is challenging since each test needs to be executed in a variety of operating contexts including heterogeneous devices, various wireless networks, and different locations. Crowdsourcing enables a mobile app testing to be distributed as a crowdsourced task to leverage the crowd in a community. However, a high test quality and expected test context coverage are difficult to achieve...
Software Defined Networks (SDN) and Network Function Virtualization (NFV) could be taken as a different expression of the overall transformation trend toward network softwarization which is deeply impacting and bringing Telecom and ICT Industry. These changes will have a broader impact on society, including aspects of regulation, policy, social impacts and new business model. A number of new stakeholders...
