The Internet of Things (IoT) considers interconnected things e.g., devices that consumes web services through the internet. Such kind of devices may vary from smart phones, smart TVs, medical devices or industrial devices. Thanks to the development of the ICT field, many standards supports the existence of the IoT devices: HTTP (Hypertext Transferring Protocol), MQTT (Message Queue Telemetry Transport),...
The usage of the service selection approaches across different dynamic service provisioning environments has increased the challenges associated with an effective method that can be used to select a relevant service. The use of service selection approach should depend on certain factors. In order to address this challenge, the literature analysis is conducted on various service selection approaches...
In many resource constrained web/cloud applications, users are given the ability to generate different kinds of reports after selecting some criteria for each report to be produced. Such criteria could, for example, be filters on certain report attributes. With limited computing resources, it is critical to prioritize the reports requested by users at any certain period of time. Then, that prioritization...
Climate Model Diagnostic Analyzer (CMDA) is a web-based information system designed for the climate modeling and model analysis community to analyze climate data from models and observations. CMDA provides tools to diagnostically analyze climate data for model validation and improvement, and to systematically manage analysis provenance for sharing results with other investigators. CMDA utilizes cloud...
The efforts and findings of the last decades of research on the formalization and the verification of Web services have given a certain level of assurance on Web services. However new challenges such as high availability and security issues are not fully addressed. In fact, Web services are exposed to attacks that appear continuously. These issues have naturally paved the way to a new research topic...
Hypertension is a chronic disease characterized by high blood pressure levels. Lack of adherence to the treatment of hypertension is a growing concern among health professionals. For this, m-Health solutions are increasingly evident, since they can automate processes and facilitate the inclusion of the patient's health conditions in a practical way and in any place, allowing the health professional...
Developing applications with intelligent context access capabilities is challenged by the difficulty of obtaining advanced context information. The complexity of the logic required for processing context information adds another barrier for developing advanced context-aware applications. In this research paper, we propose a solution that allows context information sharing and extension toward the...
Since a few years, the development of robots introduced the Cloud Computing paradigm in robotics field as “Cloud Robotics” generation. This new concept allows robots to outsource computing capabilities over the Cloud, whither the Computing involves extra power requirements that could reduce the duration of the process. In this paper, we outline a new Cloud Robotics architecture for NAO robots. Based...
It is becoming more common to see software applications taking advantage of the many RESTful web services available publicly to meet their needs rather than developing an in-house solution. This introduces the problem where failures can occur in the network or on the service provider outside the influence of a developer. This paper introduces a reliability-aware framework with a focus on availability...
Program autotuning is becoming an increasingly valuable tool for improving performance portability across diverse target architectures, exploring trade-offs between several criteria, or meeting quality of service requirements. Recent work on general autotuning frameworks enabled rapid development of domain-specific autotuners reusing common libraries of parameter types and search techniques. In this...
One of the main concerns of Cloud storage solutions is to offer the availability to the end user. Thus, addressing the mobility needs and device's variety has emerged as a major challenge. At first, data should be synchronized automatically and continuously when the user moves from one equipment to another. Secondly, the Cloud service should offer to the owner the possibility to share data with specific...
The use of digital content is increasing day after day and now it is an essential element of our day today life. The amount of stored information is so huge that it is highly difficult to manage the content especially in a distributed cloud environment. There are many open source software solutions available in cloud to handle huge amount of digital data. However none of these solutions addresses...
This paper examines the process used in scheduling limited resources for blocks of time. The paper compares a complex algorithm current used to a random assignment system on scheduling equity. This research involved scheduling contracted guides with non-regular schedules to tours in advance or the day of the scheduling process. The random assignment algorithm, which is analyzed by equity, replaces...
The focus of this research work is to investigate the problem of providing partition tolerance in cloud-based applications while maintaining application data integrity. This study looks at developing a cloud application to track sales of admission tickets to a battlefield as a motivating example. Web browsers are run inside the premises of the enterprise selling the tickets, while the rest of the...
Sensing as a Service (SenaaS) is emerging as a prominent element in the middleware linking together the Internet of Things (IoT) and the Web of Things (WoT) layers of future ubiquitous systems. An architecture framework is discussed in this paper whereby things are abstracted into services via embedded sensors which expose a thing as a service. The architecture acts as a blueprint to guide software...
Web services have been widely used in e-business, banking, and other online applications. web application architecture follows SOAP, UDDI and WSDL. QoS parameters are response time, availability, security and others are most significant for web applications. World into digital devices. the products can be used with efficient resource consumptions. Internet of things is the capability to connect every...
Web services provide functionalities to the users. Software products and services require high quality. Quality parameters of Web and cloud based applications includes scalability, balancing workload, high availability and other parameters. The objective of the paper to improve the performance of web in cloud based applications. Cloud based applications provide services to the users such as platform...
Rapid technological growth made surveillance as most promising application domain. With great extent of smart city most of the things are controlled by internet. Security is one of the applications that everyone needs to be controlled remotely. This paper presents cloud based surveillance system for live video streaming that can be surveillance from anywhere and anytime. This system provides the live...
Service-Oriented Architectures can experience a highly diversified and complex set of interactions between web services for them to compute a response to an incoming service request. Existing approaches based on modelling and control theory are good for strategic and long-term development of a data center resource dimensioning necessary to respond within the boundaries of Service Level Agrements....
With the development of the network data and use the change of demand, extension from cloud computing cloud storage become the research focus and hot spot. This paper mainly introduces the characteristics of cloud storage technology, and analyze the hierarchical structure of the cloud storage service, and then analyzing the data storage structure of the cloud storage service, emphasis on reliability...
