Scalable and diagnosable are the two most crucial needs for voice call quality assessment in mobile networks. However, while these two requirements are widely accepted by mobile carriers, they do not receive enough attention during the development. Current related research mainly focuses on audio feature analysis, which is costly, sensitive to language and tones, and infeasible to be applied to large-scale...
Mobile applications require quality assurance approaches tailored to their peculiarities, such as context awareness and platform diversity. Furthermore, time limitations and budget restrictions in mobile application development are typical characteristics that need to be addressed. In a prior work, we proposed the usage of a mobile-specific failure pattern classification to focus quality assurance...
A mobile trolley allows engineers to do integration work at various parts of the satellite body, thus preventing mishandling of the satellite. Unfortunately, the existing height multi-purpose satellite trolley in Satellite Assembly, Integration and test facility of Malaysia Space Centre is not an adjustable type and there is no platform to work safely around the satellite. Existing conditions in the...
In this paper, we study the implementations of multiple testing procedure (MTP) for multiband spectrum sensing in cognitive radio, more precisely using Holm's sequentially rejective algorithm and Benjamini-Hochberg's algorithm. MTP is appropriate for multiband spectrum sensing when we want to provide control on the decision errors at the system level, not per subband. This approach is motivated when...
The authors have developing mobile device evaluation and testing platform to evaluate the mobile malware. Using the platform, the authors have created several courses in mobile device security. One of the important requirements is to provide students with a safe and sandboxed environment for malware analysis. Other features include tool enhanced lab environment, updated malware repository, log collection...
During the last years, location-based services (LBS) became one of the most popular features of mobile devices like smartphones or tablets. Basically, reactive LBS provide means to access location-specific content upon request by the user, whereas their proactive counterparts are used to push location-specific content to the user as soon as a dedicated zone - called geofence - is entered or left....
This research examines an assessment system that combines a mobile device with NFC (Near Field Communication) technology. Teachers attach or embed NFC tags into answer choices and students answer each question by bringing their mobile phone close to the answer that they think is the correct one. A four-week experiment shows that this assessment method takes more time than a traditional one. Also,...
In this paper, we present a driving license test APP system for traffic education. The system provides learning materials and the adaptive simulation quiz. Questions in the quiz are individually generated according to the user profile and the designed boosting algorithm. The experimental result revealed that our APP system showed statistically significant better score in the driving license exam.
The paper presents the setup and results of a mobile application usability test using mobile eye-tracking glasses. Quasi-real conditions of the natural environment were assured for the testing in order to avoid incidental disorders possible in natural conditions and the weaknesses of a fully lab experiment. The experiment methodology was developed and used to carry out a usability test of the mobile...
Due high popularization of cloud services and the use of a wide range of mobile devices with different environments and platforms, a new model to offer software test service emerged, called Testing as a Service (TaaS). It uses cloud infrastructure to provide on-demand testing services on cloud for end users at any time. Nowadays there are many studies about different services about TaaS. Based on...
The World Health Organization (WHO) launched universal strategy in HIV prevention in 2012 called “Test & treat HIV prevention”. (TATF) Test and Treat Follow-up is proposed to be a follow-up platform to support the follow-up of HIV carriers by integrating information technology approaches in fields of database, communication, and mobile application. TATF consists of three main modules: 1) The clinical...
With the increase of the mobile network complexity, minimizing the level of human intervention in the network management and troubleshooting has become a crucial factor. This paper focuses on enhancing the level of automation in the network management by dynamically learning the mobile network cell states and improving the anomaly detection on the individual cell level taking into consideration not...
Mobile-app quality is becoming an increasingly important issue. These apps are generally delivered through app stores that let users post reviews. These reviews provide a rich data source you can leverage to understand user-reported issues. Researchers qualitatively studied 6,390 low-rated user reviews for 20 free-to-download iOS apps. They uncovered 12 types of user complaints. The most frequent...
The paper evaluates methods of selecting mobile devices (i.e., Smartphones and tablets) to test mobile software applications. Due to the number of such devices on the market and the variations in their characteristics, it is hard to guarantee that an application will work properly on all devices. Software faults found only in certain devices are known as device-specific faults. The goal of this research...
Currently, there is a lack of tools or techniques which can clearly handle the complexity related to inter-component communication while developing Android applications. We propose a conceptual model which represents the inter-component communication at a higher abstraction level. We also propose a technique to derive test case from the model. The model can be useful in handling complexity at various...
Monkey Fuzz Testing (MFT), a form of random testing, continues to gain popularity to test Android apps because of its ease of use. (Untrained) programmers use MFT tools to fully automatically detect certain classes of faults in apps. A challenge for these tools is the lack of a stopping criterion -- programmers currently typically stop these tools when they run out of time. In this paper, we use the...
This paper explores IPv6 in mobile wireless sensor networks (WSNs). An indoor WSN mobile sensor network testbed of length 24m was built and used for mobile WSN testing. The test network enabled the use of one or two moving nodes and six stationary nodes. A Java based web application called WSNWeb was implemented that displays and records real-time route topology changes and received sensor data. We...
Mobile technology in learning process is quite demanding, nowadays. It has a huge potential as a learning tool and also can be used as distance learning environment. Towards this, many mobile learning application tools have been developed in order to meet the user demand. This generates the idea of developing Arabic grammar learning tool due to most of people especially UiTM Kedah students have lack...
The visually impaired face a number of challenges when performing their daily tasks. These tasks may be differentiating objects that have similar shapes or knowing the content of a restaurant menu. In fact, there is an increasing interest in developing effective solutions that can help the visually impaired to recognize objects. However, automatic techniques cannot answer most of the questions asked...
This paper reviewed the research on mobile IP technologies for improving handover performance. After making comparison between different test methods used in those researches, the Testing for Handover Performance based on Android Intelligent Mobile Equipment (THPAIME) is proposed. Based on the open-source project OAI PMIPv6, the platform for testing Proxy Mobile IPv6 (PMIPv6) is constructed. In our...
