In this paper, and in the context of a course of 1st cycle in Informatics, and following the guidelines of the Information Systems courses provided by ACM/AIS, we propose the use of Google tools and Lucidchart modeling tool, aligned with Bloom's taxonomy in our model BML Context Oriented (BML-CO) in a Requirements Engineering course based on Unified Modelling Language (UML) to modeling and specify...
Mobile surveys are an important research tool. In mobile health, triggering survey questions based on patient health, context, and other external information can aid in tailoring a survey to each specific user's particular situation. However, creating such a survey with existing systems is burdensome. Therefore, this paper presents a novel information system to ease the creation and deployment of...
For the last decade, researchers are showing interest in mobile cloud computing (MCC) for its promising potentiality. It combines cloud computing and mobile computing providing better quality of service to user with mobile device. Resource famished applications can now be executed on mobile devices by offloading the task on cloud. Major research areas in MCC are how, where and when to offload a task...
Several learning technologies have been developed over the years in order to help distance learning process. However, those technologies are still not enough to give the proper interaction between their users and the technologies themselves. It is caused by the absence of the technologies ability to give context based on their users conditions. When human interacts with each other, they understand...
This paper presents a new approach to the continuous K nearest neighbors search (C-KNN) problem, in the context of road networks. Our approach is based on Formal Concepts Analysis (FCA), which has a mathematical foundation. FCA offers an abstraction of the network based on the neighborhoods. We build the concept lattice based on the binary relations between the target points as well as theirs properties...
The use of mobile devices is rapidly growing each year due to their portability and convenience. User experience and battery life are both crucial topics in the advancement of these devices. Sensing the light environment of a mobile device and adapting the output of the device accordingly can create positive results for both user experience and battery life. In this paper, we concentrate on different...
We live in a world of intelligent robots, drones and mobile phones/assistants. The technologies behind these products are heralded by a new wave of deep learning applications ported on mobile devices. The robotic and vision technologies behind these products will shift the applications of electronic devices to a more superior level of intelligence that will change our world. From a hardware point...
With information technology and the Internet developing fast, people gradually walk out of the time of information deficient and enter the era of information overload. Whether information consumers or information producers are faced with big challenge: how to obtain or sell the information. Recommendation system is a key to this problem. Traditional recommendation system focuses on connecting user...
This paper presents the outcome of a preliminary investigation into the use of mobile apps as a dynamic capability tool by start-up entrepreneurs. 19 business start-ups in Lagos Nigeria were involved in this study, with average enterprise age of 11.5 months in service industry. After strategic use of customized mobile app for 12 weeks, it was observed that average profit, customer-base and staffing...
ZoneIT — at the University of the Western Cape renamed in UDUBSit — was first developed by the University of Ghent in Belgium as a sharing application for and by the student community. This app is adapted and contextualised to the UWC context by way of a living lab approach. This paper describes and analyses the results from the needs analysis, which formed the first step in the living lab approach...
Mobile health (or mHealth) describes the utilisation of wireless mobile communications devices in public and private healthcare. These include, but are not limited to, mobile telephones, personal digital assistants, and patient monitoring devices. A number of researchers recognize the potential of mHealth capabilities to address healthcare issues within developing countries. Although the outcomes...
In this paper, we develop effective solutions for enabling mobile sensing/data collection in community IoT deployments where sensing/communication coverage is intermittent and varying. Specifically, we address the optimized upload planning problem, i.e. determine optimal schedules for upload of gathered information to enable timely data collection in dynamic settings. We develop a two-phase approach...
With the widely use of smart devices and rapid development of communication technologies, it becomes easier for base stations to obtain the context information of users. The context information can be utilized to optimize system resource allocation. This paper focuses on context- aware unicast cellular networks. Assuming that some channel state information (CSI) can be predicted based on user context...
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets to present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could implement with the help of mobile devices. The basic idea behind the Physical Web is to navigate and control physical...
The Home Subscriber Server (HSS) within the packet core of the Long Term Evolution (LTE) is a key node leveraged for essential operations, such as mutual authentication and access control. This centralized node is essential for the overall network operation as it is the cornerstone of the cryptographic functions executed in a mobile network. It stores several parameters for each subscriber, including...
End-to-end communications with Internet-integrated sensing devices will contribute to the enabling of many of the envisioned IoT applications. Communication technologies with this purpose are currently being designed based on the 6LoWPAN adaptation layer, and of particular interest is CoAP (Constrained Application Protocol). The support of security in end-to-end CoAP communications with mobile Internet-integrated...
A promising architecture for content caching in wireless small cell networks is storing popular files at small base stations (sBSs) with limited storage capacities. Using localized communication, an sBS serves local user requests, while reducing the load on the macro cellular network. The sBS should cache the most popular files to maximize the number of cache hits. Content popularity is described...
Video streaming provided by Over-The-Top (OTT) service providers through a cellular network is a common usage scenario for many people today. While video streaming will work reasonably well in a stationary scenario, several issues arise for mobile users. For instance, travelling through short areas without cellular coverage, such as an automobile tunnel, will often result in quality degradation or...
Being a convenient replacement for their desktop counterparts, social Web applications are nowadays widely employed in diverse aspects of human endeavour, including education. Current body of knowledge on assessment of social Web applications is composed of studies that were mainly focused on quantitative measurement of their quality when they were used in their primary setting. On the other hand,...
This paper investigates the network offloading capability of Device to Device (D2D) communication when combined with content caching. We consider a mobile network where a proportion of users are equipped with caches from which other users can retrieve contents using direct D2D communications. In this case, the offloading capacity depends both on the cache performance and the quality of the D2D links...
