Cloud radio access network (C-RAN) and mobile edge computing (MEC) have emerged as promising candidates for the next generation access network techniques. Unfortunately, although MEC tries to utilize the highly distributed computing resources in close proximity to user equipments equipments (UE), C-RAN suggests to centralize the baseband processing units (BBU) deployed in radio access networks. To...
The concept of the cloud is no longer limited to providing remote hardware or platform support with the development of cloud computing technology. Instead, it encapsulates all aspects of the content in computer field into service invoked by others. As an important part of software, data resource has become core services to the cloud platform in areas such as collaborative manufacturing and collaborative...
Cloud computing has recently attracted a substantial amount of attention from both industry and academia. Its growing demand gives normal users an opportunity to sell their local resources to the cloud market, which introduces new challenges for the existing coarse-grained pricing models. In this paper, we examine the potential of applying continuous double auction framework to handle these heterogeneous...
Smart grids are recognized as the next-generation power grid that uses digital information and communications technology to create an advanced, automated, and efficient energy network among a wealth of electronic appliances, meters, and energy producing and distributing devices. As more complex and distributed interactions among these different components are envisioned, an open, scalable, and manageable...
The multi-tier architecture is prevalently adopted by cloud applications, such as the three-tier web application. It is highly desirable for both tenants and providers to provide virtual networks in an efficient and elastic way, where tenant applications can automatically scale in or out with varying workloads and providers can accommodate as many requests as possible in the underlying network. However,...
The emergence of cloud computing as an efficient means of providing computing as a form of utility can already be felt with the burgeoning of cloud service companies. Notable examples including Amazon EC2, Rackspace, Google App and Microsoft Azure have already attracted an increasing number of users over the Internet. However, due to the dynamic behaviors of some users, the traditional cloud pricing...
This paper introduces GENI Cinema (GC), a system that provides a scalable live video streaming service based on dynamic traffic steering with software defined networking (SDN) and demand driven instantiation of video relay servers in NSF GENI's distributed cloud environments. While the service can be used to relay a multitude of video content, its initial objective is to support live video streaming...
The state-of-the-art cloud computing service has attracted significant interests from the Internet users. However, in the existing cloud platforms, the cloud users are pure consumers; their local resources, though abundant, have been largely ignored. In this paper, we for the first time explore the resource pricing as well as the incentive issues in SpotCloud, a real-world system that enables customer-provided...
Cloud computing is the promising key technology to build future architecture of massive IT systems and one of key benefits of cloud computing is to provide its customers with elastic resources according to the fluctuation of request workloads. In this paper, we propose adaptive resource management policy to handle requests of deadline-bound application with elastic cloud. Adaptive resource management...
Federated clouds establish a model for independent cloud providers to cooperate and share resource to cope with unforeseen demand loads. One of the challenges in federated clouds is how to find suitable virtual machines to locate resource requests, with constrains of multiple resource attributes. This paper proposes a Gossip-based Hybrid Multi-attribute Overlay (GHMO) for effective resource discovery...
Nowadays, streaming media and web pages have occupied the most bandwidth on the Internet. And it's important to remain the scalability, performance, fairness and resources management potential while providing the Web Service. In this paper, we have proposed a new Web Service Structure of Combining P2P and CDN Technologies. By building a P2P Content Distribution Network (CDN), peers collaborate to...
In recent years, the technology of cloud computing has been widely applied in e-business, e-education and etc.. Cloud computing platform is a set of scalable large-scale data server clusters, it provide computing and storage services to customers. The cloud storage is a relatively basic and widely applied service which can provide users with stable, massive data storage space. Our research shows that...
