This paper studies the design and analysis of networked multiagent predictive control systems via cloud computing. A cloud predictive control scheme for networked multiagent systems (NMASs) is proposed to achieve consensus and stability simultaneously and to compensate for network delays actively. The design of the cloud predictive controller for NMASs is detailed. The analysis of the cloud predictive...
Software-defined networking (SDN) has separated control and forwarding planes, which is a powerful approach to enable network virtualization by SDN hypervisors to share physical SDN networks among multiple virtual SDN in cloud data center. However, the centralized control and virtual network shared physical network are delicately weak and easy to failure if virtual topology embedding is not properly...
The recent deployment of novel network concepts, such as M2M communication or IoT, has undoubtedly stimulated the placement of a new set of services, leveraging both centralized resources in Cloud Data Centers and distributed resources shared by devices at the edge of the network. Moreover, Fog Computing has been recently proposed having as one of its main assets the reduction of service response...
This article presents a new model and a resolution algorithm, based on Tabu Search, for the assignment of Virtual Machines (VMs) to servers in a data center. We propose a Mixed Integer Programming (MIP) model that optimizes the Quality of Service (QoS) and power consumption of applications, taking into account their communication traffic and dynamic aspects. A hierarchic method and a Tabu Search heuristic...
Nowadays data centers are attracting a huge attention of researchers. The performance of the data centers is key to hold the successes of cloud computing. As dimensions of cloud computing are enhanced by offering multiple services, the responsibility of service provider escalates many folds. Even hosting single service per data center requires promising conduct round the clock. Incompetency in fulfilling...
The recent technological advances related to computing, storage, cloud, networking and the unstoppable deployment of end-user devices, are all coining the so-called Internet of Things (IoT). IoT embraces a wide set of heterogeneous services in highly impacting societal sectors, such as Healthcare, Smart Transportation or Media delivery, all of them posing a diverse set of requirements, including real...
Mobile users run complex applications increasingly, requiring much more computing power and energy. Cloud-enhanced small cell networks, endowing small cells with cloud computing abilities, extend mobile devices capabilities and battery lifetime by providing them with the advantages of instant and high-rate access to the cloud servers. However, conventional offloading policy can not fully exploit these...
The member cardinality in the cluster-based Vehicular Cyber-Physical Systems (VCPS) is an important parameter in the cluster maintaining and updating. It also has a great influence on private cloud computing scheduling, topology controlling and even some relevant applications. However the traditional member cardinality change verification time is too long and can not satisfy the requirement of VCPS...
Optical networks have been shown to be the most viable solution for inter-data-center network implementation. Furthermore, elastic optical networks incorporating virtualization technology can significantly introduce agile delivery of cloud services. In this paper, we present resilient design of an inter-data-center network over an elastic optical network backbone aiming at minimum outage probability...
Cloud computing that was introduced when local facilities could not any more satisfy access demands along with the increase of network bandwidth and diversity of services, breaks constraints of physical deployment and delivers varieties of services in its hardware/software virtualized manner. Being inherited the idea, the NaaS as a new presented research field ever since the cloud computing being...
Cloud computing is the leading edge concept which combines the advantages of several existing computing concepts for the betterment of the Information and Communication Technology (ICT) business. This new business model aims at moving the services such as software, platform and/or infrastructure to a shared pool of resources which are mainly housed in the data centers. In this paper, we propose a...
In the cloud computing era, the goal of data center network is not only to interconnect a large number of servers, but also to provide low latency and high bandwidth. A new 2-layer architecture, C-tree, is proposed for cloud computing in this paper. It is a flat topology, in which the horizontal traffic's latency is obviously lower than in traditional three-layer architectures. Also, C-tree can provide...
