    In the framework of the Future Internet, the aim of the Quality of Experience (QoE) Control functionalities is to track the personalized desired QoE level of the applications. The paper proposes to perform such a task by dynamically selecting the most appropriate Classes of Service (among the ones supported by the network), this selection being driven by a novel heuristic Multi-Agent Reinforcement Learning (MARL) algorithm. The paper shows that such an approach offers the opportunity to cope with some practical implementation problems: in particular, it allows to face the so-called “curse of dimensionality” of MARL algorithms, thus achieving satisfactory performance results even in the presence of several hundreds of Agents

    Decision support for personalized cloud service selection through multi-attribute trustworthiness evaluation

    Facing a customer market with rising demands for cloud service dependability and security, trustworthiness evaluation techniques are becoming essential to cloud service selection. But these methods are out of the reach to most customers as they require considerable expertise. Additionally, since the cloud service evaluation is often a costly and time-consuming process, it is not practical to measure trustworthy attributes of all candidates for each customer. Many existing models cannot easily deal with cloud services which have very few historical records. In this paper, we propose a novel service selection approach in which the missing value prediction and the multi-attribute trustworthiness evaluation are commonly taken into account. By simply collecting limited historical records, the current approach is able to support the personalized trustworthy service selection. The experimental results also show that our approach performs much better than other competing ones with respect to the customer preference and expectation in trustworthiness assessment. © 2014 Ding et al

    Service computing is one of Internet-based computing, whereas the shared configurable resources (e.g., infrastructure, platform, and software) are provided to computers and other devices are as services. Strongly promoted by the leading industrial companies like, Amazon, Google, Microsoft, IBM, etc, In recent years, service computing are quickly becoming popular. Applications are deployed in real time environment are typically large scale and complex. The rising popularity of service computing, it is how to build high-quality service applications it becomes an urgently required research problem. In Similar, the traditional component-based systems, cloud applications are typically involves multiple cloud components communicating with each other over application programming interfaces, through web services. On-functional performance of cloud services are usually described by the quality-of-service (QoS). QoS is an important research topic in cloud computing. When the creation optimal cloud service selection from a set of functionally corresponding services, QoS values are of cloud services provided the valuable information to assist decision making. The component-based systems, software components are invoked locally in tradition, while in cloud applications, the cloud services are invoked remotely by Internet connections. To evade the slow and expensive real-world service invocation QoS ranking prediction framework is used. This framework requires no extra invocations of cloud services when making QoS ranking prediction can implement novel collaborative filtering approach to recommend the web services with improved performance.
