Trends and Directions in Cloud Service Selection

With the growing popularity of cloud computing the number of cloud service providers and services have significantly increased. Thus selecting the best cloud services becomes a challenging task for prospective cloud users. The process of selecting cloud services involves various factors such as characteristics and models of cloud services, user requirements and knowledge, and service level agreement (SLA), to name a few. This paper investigates into the cloud service selection tools, techniques and models by taking into account the distinguishing characteristics of cloud services. It also reviews and analyses academic research as well as commercial tools in order to identify their strengths and weaknesses in the cloud services selection process. It proposes a framework in order to improve the cloud service selection by taking into account services capabilities, quality attributes, level of users knowledge and service level agreements. The paper also envisions various directions for future research.

A Simulation Study of IPv6 to ATM Flow-Mapping Techniques

This paper presents a simulation study into the problem of conveying Internet protocol (IP) packets over an asynchronous transfer mode (ATM) network in cases where quality of service (QoS) is an important consideration. The main focus of the work is on mapping IP packet flows onto ATM cell streams, particularly for the purpose of maintaining the QoS requirements of continuous media (audio and video) traffic. Simulation models of two different flow-mapping scenarios are described, and results of an evaluation of the flow-mapping process are presented. These results are also used to validate an analytical solution to the problem, which has been developed in a separate but related piece of work.

Towards an open architecture for Smart Grid communications: Possible pointers from multiservice network research

This paper addresses the challenge of developing communications architecture for the Smart Grid. It considers the similarity between the QoS requirements for Smart Grid communication and those addressed by previous work into multiservice networks and QoS Architectures. It discusses this previous work within the context of Smart Grid requirements and identifies the contribution it could make to the development of Smart Grid communications architecture.

Network level Quality of Service (QoS) challenges for smart grid measurement and control systems

This paper focuses on the firm real-time requirements of Time-Critical Wide Area Measurement and Control systems, that are expected to play a major role in future Smart Grids. It analyses the operation of these systems and identifies their communication traffic characteristics. It shows that these characteristics are significantly different to those of the current near real-time Wide Area Measurement applications that provide visualization to support manual grid control. It then discusses the performance evaluation of these time critical systems and presents the second stage in an ongoing body of work aimed at developing models and techniques to carry out the performance evaluation process. It presents some preliminary results and outlines the direction for future work.

A control framework to develop smart grid communications: possible pointers from multiservice network research

This paper addresses the challenge of developing an architecture for the smart grid with the particular focus to support smart grid communication. It considers the smart grid system in general to identify the relationship between the power distribution and communication networks, and then focuses mainly on smart grid communication requirements. It observes the similarity between the quality of service (QoS) requirements for smart grid communications and those identified in multiservice networking. It reviews the principles of open communication and introduces architectures for open communication that have been enhanced to meet the requirements of multiservice. It discusses previous research into multiservice with a review into recent work focused on meeting the multiservice requirements of smart grid communications. Based on these, the paper presents key specific pointers toward defining a contextual control framework for the data transport system of the smart grid.

Analysis of the Suitability of Satellite Communication for Time-Critical IoT Applications in Smart Grid and Medical Grade Networks

Satellite networks are seen as having the potential to play an important role in machine-to-machine (M2M) communications and the Internet of Things (IoT), which in turn is seen as being important to a number of service sectors. However, certain M2M applications have bounded latency requirements that in some cases may be quite stringent. Satellite networks generally have much higher latency than wired networks and therefore may not be able to meet the requirements of all M2M applications. This paper compares the latency requirements of certain time-critical applications with reported satellite network latency and address the problem of latency evaluation of networks to support these types of applications.

A framework for peer-to-peer video streaming over WiMax

Real-time peer-to-peer (P2P) streaming video traffic will constitute a significant proportion of future Internet traffic. With the availability of WiMAX, a large number of these peers will be ubiquitous and located on WiMAX based mobile nodes across the Internet. This chapter proposed a framework for providing quality of service (QoS) to the overlay P2P network over a WiMAX infrastructure. The work integrates traffic engineering and analytical based approach and has been validated with results from experiments.
