It is well known that the fragmentation of Android ecosystem has caused severe compatibility issues. Therefore, for Android apps, cross-platform testing (the apps must be tested on a multitude of devices and operating system versions) is particularly important to assure their quality. Although lots of cross-platform testing techniques have been proposed, there are still some limitations: 1) it is...
Operation services are reusable and shareable units of configuration code executed by configuration management tools (CMTs), achieving continuous deployment and continuous delivery. With the prevalence of DevOps (Development and Operations), thousands of operation services have been developed for various software systems, and they are publicly available through the online repositories of popular CMTs...
With the development of computing capability and display size in computing hardware, mobile terminals like iPhone or iPad have been more and more accepted as a tool to help radiologists to examine medical images of patients in order to give more accurate diagnostic conclusion through server. The radiologists can observe the images by interacting them with different hand gestures to translate, rotate...
With the efficient Internet access and increasing powerful computing capabilities of mobile device, the mobile botnet has becoming an emerging threat in the mobile Internet. In this paper, we propose a novel mobile botnet using the cloud platform consisting with multiple message push servers. The path delay is measured as the metrics to classify bots into different groups. A weighted round-robin algorithm...
In recent years, the rapid development of intelligent dietary planning mobile systems, combined with the cloud technology, provides more intuitive and convenient experience for users on the diet recording and suggestion. However, this mobile-cloud structure will cause the privacy issue. Unlike the past researches which mainly focus on the user interface, response speed and suggestion accuracy, we...
Dynamic Adaptive Streaming over HTTP (DASH) is being adopted as a cost effective means for multimedia delivery. User Adaptive Video (UAV) is a new technique that exploits the perceptual limits of the human visual system to modulate a video stream's bit rate based on the viewing conditions, such as viewing distance and ambient illuminance, resulting in significant bandwidth reduction without perceived...
In this paper, we consider a multiple access channel, where multiple users equipped with energy harvesting batteries communicate to an access point. The users are supposed to share the channel via Time Division Multiple Access (TDMA). In many existing works, it is commonly assumed that the users' energy harvesting processes and storage status are known to all the users before transmissions. In practice,...
To guarantee quality of the service, services need to be tested to ensure the service quality. But most of existing testing service can't provide multi-type testing and deploy testing clients concurrently in different regions. To overcome these problems, in this paper, a cloud testing service combine cloud computing and multi-testing tools is proposed. Using the proposed service user can deploy the...
In traditional cloud computing, elastic computing can be provided by increasing or decreasing the number of virtual machines (VM). However, the resource needed by applications change swiftly. This coarse-grained resource allocation approach is not a perfect way to satisfy the demand of the workload in short term. In this paper, we present a fine-grained resource allocation method in virtualized servers...
In the era of Internet, one of the most ultimate goals is that users can seamlessly access to any computing application or service at anywhere anytime. Computing infrastructuralization is the path to gradually address the challenge. In this work, elop computing is proposed that encapsulates and integrates various computing elements as services, benefiting from existing advanced computing technology,...
With development of business process management technology and information technology, we can simulate business processes. How to describe business process by structural language and check business process model are the issues. We develop a business processes system by SOA and model business process actions by Pi-calculus and check the model by MWB.
Open Source Private Cloud (OSPC) is a full stack of private cloud solution based on Open Stack to help user enable and manage private cloud environment. Intel Intelligent Power Node Manager is a platform resident technology with power and thermal policies. In this paper, we introduce how to manage power in cloud computing effectively by integrating Intel Node Manager with OSPC and define this resolution...
Cloud computing is a new model and technology that leverage the efficient pooling of on-demand, self-managed virtual infrastructure. Virtualization packages the applications in the form of Virtual Machine (VM) and provides significant benefits by reconfiguring the VMs dynamically. VM reconfiguration is hard and complicated, and existing work addressed the problem with diverse objectives by answering...
As a rising application paradigm, cloud computing enables the resources to be virtualized and shared among applications. In a typical cloud computing scenario, customers, Service Providers (SP), and Platform Providers (PP) are independent participants, and they have their own objectives with different revenues and costs. From PPs' viewpoints, much research work reduced the costs by optimizing VM placement...
The rising wave of internet applications has led to the rapid development of streaming media technology. This paper proposes time-triggered events algorithm using a script object transformation to XML documents to create the automatic EFP studio system for real-time editing and broadcasting of audio/ video on media server. The system provides the user access to web multiple cameras and AV equipment...
With the development and popularization of the Internet/intranet technology, computerized tests will gradually replace traditional paper and pen-based tests on many aspects. It has particular practical significance to explore and study computer network-based tests to objectively and accurately evaluate certain abilities and levels of students to improve the learning efficiency. Agent is a software...
Recently, all-IP intelligent video surveillance/door system is one of the attractive and important applications in the world. However, because the current Internet architecture cannot provide sufficient QoS for such kind of real-time applications, the performances of them are often poor under congested or interfered Internet environment. When Internet traffics are congested or interfered, the frame...
In this paper we study on the alert analysis technique of Network Situation Awareness (NSA). The overwhelming alerts make it challenging to understand and manage. Although there are already many alert analysis techniques proposed in Intrusion Detection research area, most of them are used to reduce false positives and false negatives. However, the NSA requires the alert analysis techniques to offer...
The broadcast method is the most efficient approach to deliver a popular video for utilizing bandwidth. By combining the Fibonacci and staircase methods, this paper presents a hybrid broadcasting method with low buffer requirement to deliver a constant bitrate compressed video. The proposed method allows users with bandwidth of double of the consumption rate to download and watch the video without...
Research on streaming media data distribution via Peer-to-peer (P2P) application layer multicast (ALM) network is popular these years. This paper presents an unstructured P2P overlay which is used in the Banacast system. It analyzes which architecture could be taken use of in the P2P live streaming system, how to speed up the progress of joining P2P network with some strategies and algorithms, how...
