Video streaming is a traditional network traffic application with high bandwidth and delay requirements.
Optimizing the network infrastructure for video streaming traffic is an ongoing challenge. In this paper, we consider the case of unicast live video streaming over parallel channels with different reliability and bandwidth, for example, wireless channels. While video streaming over parallel channels was proposed before, each frame in the video data was considered to be equally important.
As a result, important frames could be sent over less noisy channels, which impacts perceived video quality at the receiver. We show that by using a protocol such as the Stream Control Transmission Protocol (SCTP), we can identify higher reliability channels in a set of potential channels between the video source and consumer. To maximise the experienced video quality at the receiver, we then identify more important data in the video stream and send it over the better channels. We simulate the proposed solution and demonstrate the effectiveness of our proposed framework for concurrent multipath video.

Mobile devices compatibility testing strategy via crowdsourcing

Purpose: This paper aims to support small mobile application development teams or companies performing testing on a large variety of operating systems versions and mobile devices to ensure their seamless working.

Design/methodology/approach: This paper proposes a “hybrid crowdsourcing” method that leverages the power of public crowd testers. This leads to generating a novel crowdtesting workflow Developer/Tester- Crowdtesting (DT-CT) that focuses on developers and crowd testers as key elements in the testing process without the need for intermediate as managers or leaders. This workflow has been used in a novel crowdtesting platform (AskCrowd2Test). This platform enables testing the compatibility of mobile devices and applications at two different levels, high-level (device characteristics) or low-level (code). Additionally, a “crowd-powered knowledge base” has been developed that stores testing results, relevant issues and their solutions.

Findings: The comparison of the presented DT-CT workflow with the common and most recent crowdtesting workflows showed that DT-CT may positively impact the testing process by reducing time-consuming and budget spend because of the direct interaction of developers and crowd testers.

Originality/value: To the authors’ knowledge, this paper is the first to propose a crowdtesting workflow based on developers and public crowd testers without crowd managers or leaders, which light the beacon for future research in this field. Additionally, this work is the first that authorizes crowd testers with a limited level of experience to participate in the testing process, which helps in studying the behaviours and interaction of end-users with apps and obtains more concrete results.

Purpose: This paper aims to gauge developers’ perspectives regarding the participation of the public and anonymous crowd testers worldwide, with a range of varied experiences. It also aims to gather their needs that could reduce their concerns of dealing with the public crowd testers and increase the opportunity of using the crowdtesting platforms.

Design/methodology/approach: An online exploratory survey was conducted to gather information from the participants, which included 50 mobile application developers from various countries with diverse experiences across Android and iOS mobile platforms.

Findings: The findings revealed that a significant proportion (90%) of developers is potentially willing to perform testing via the public crowd testers worldwide. This on condition that several fundamental features were available, which enable them to achieve more realistic tests without artificial environments on large numbers of devices. The results also demonstrated that a group of developers does not consider testing as a serious job that they have to pay for, which can affect the gig-economy and global market.

Originality/value: This paper provides new insights for future research in the study of how acceptable it is to work with public and anonymous crowd workers, with varying levels of experience, to perform tasks in different domains and not only in software testing. In addition, it will assist individual or small development teams who have limited resources or who do not have thousands of testers in their private testing community, to perform large-scale testing of their products.

Hybrid Crowd-powered Approach for Compatibility Testing of Mobile Devices and Applications 

Testing mobile applications (apps) to ensure they work seamlessly on all devices can be difficult and expensive, especially for small development teams or companies due to limited available resources.

There is a need for methods to outsource testing on all these models and OS versions.
In this paper, we propose a crowdsourced testing approach that leverages the power of the crowd to perform mobile device compatibility testing in a novel way. This approach aims to provide support for testing code, features, or hardware characteristics of mobile devices which is hardly investigated. This testing will enable developers to ensure that features and hardware characteristics of any device model or features of a specific OS version will work correctly and will not cause any problems with their apps. It empowers developers to find a solution for issues they may face during the development of an app by asking testers to perform a test or searching a knowledge base provided with the platform. It will offer the ability to add a new issue or add a solution to existing issues. We expect that these capabilities will improve the testing and development of mobile apps by considering variant mobile devices and OS versions on the crowd.

The Key Considerations In Building A Crowd-testing Platform For Software Developers

External testing of mobile software on a larger number of mobile devices by several users is often needed to ensure quality. Currently, the evidence as to what extent developers accept large-scale crowd-testing is limited. This paper aims to (1) gauge developers’ perspectives with respect to the participation of the public and anonymous crowd testers, with varied experiences; (2) gather the developers’ needs that could reduce their concerns of dealing with the public crowd testers and increase the opportunity of using the crowd-testing platforms. An online exploratory survey, conducted to included 50 Android and iOS developers from different countries with diverse experiences. This paper revealed several findings including the information that must be provided by developers and crowd testers for achieving effective crowd-testing process; the factors that can ensure the reliability and accuracy of the results provided by the public crowd testers. The findings conclude that (90%) of developers are potentially willing to perform testing via the public crowd testers worldwide. This on condition that several fundamental features were available which enable them to perform more realistic tests without artificial environments on large numbers of devices. The results also demonstrated that a group of developers does not consider testing as a serious job that they have to pay for, which can affect the gig-economy and global market. We aim at helping the individual or small development teams who have limited resources to perform large-scale testing of their products.
