This work develops a cloud-fog computing architecture for information-centric Internet-of-Things (IoT) applications with job classification and resource scheduling functions. The two designed functions support quality of service (QoS) by classifying IoT applications and scheduling computing resources. An innovative scheduling mechanism is developed to optimize the dispatch of cloud and fog resources...
The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework. This paper presents the designed 5G-Crosshaul architecture,...
Cloud-based Radio Access Network (C-RAN) is a promising architecture for future cellular networks, in which Baseband Units (BBUs) are placed at a centralized location, with capacity-constrained fronthaul connected to multiple distributed Remote Radio Heads (RRHs) that are far away from the BBUs. The centralization of signal processing enables the flexibility for coordinated multi-point transmission...
In mixed-criticality systems, resource management services are required to recognize and fulfill system wide high-level constraints, e.g., end-to-end deadlines. This is not possible through individual resources in isolation. Instead, a system-wide view is necessary which requires system-wide decisions. In the European FP7 project DREAMS, services for system-wide adaptability of mixed-criticality applications...
In this paper, we suggest a novel multi-GPU scheme that can provide flexible interconnections between multi-GPUs and displays with no additional hardware by implementing new software features, while avoiding system overhead. Our proposed scheme offers the complete concept of windowing system and GPU driver for single-node multi-GPU system on multiple display environments.
Large-scale self-organised systems, such as distributed community energy systems, have called for coordination approaches that are able to deal with issues such as heterogeneity, inter-dependence and dynamic variability. Holonic institutions have been proposed as an approach to converging the structuration required for multi-scale, multi-criteria optimisation in nested enterprises with the formal...
Cloud computing has been established as a novel approach for computing where virtualized resources are available on demand. This permits the user to concentrate on the functional area and frees her/him from the burden of setting up data centers, hardware, software, network and licensing etc. Cloud computing helps in cost saving, easy accessibility, security, and 24×7 availability of resources to the...
The selection of resources, particularly VMs, in current public IaaS clouds is usually done in a blind fashion, as cloud users do not have much information about resource consumption by co-tenant third-party tasks. In particular, communication patterns can play a significant part in cloud application performance and responsiveness, specially in the case of novel latency-sensitive applications, increasingly...
In the era of the Internet-of-Vehicles (IoV), all components in an Intelligent Transportation System (ITS) can be connected to improve the traffic safety and transportation efficiency. In order to maximize the utilization of the resources, e.g., computation, communication and storage resources, the cloud computing technique could be integrated into vehicular networks. Meanwhile, a cloud-assisted vehicular...
Mobile operators are moving towards sharing network capacity in order to reduce capital and operational expenditures, while meeting the increasing demand for mobile broadband data services. Radio access network sharing is a promising technique that leads to reduced number of physical base station deployments (required for coverage enhancement), increased base station utilization, and reduced overall...
In today's scenario, almost all research and business organizations rely heavily on IT infrastructure. Cloud computing is an emerging paradigm that has caused significant changes in the field of computing. The infrastructure provisioned to users via cloud includes expensive hardware, storage, network etc. The infrastructure is made available to end users on demand basis and in pay-as-you-say manner...
Experimentation using testbeds has become increasingly important in the area of Community Networking research. An example is Community-Lab, a distributed testbed to support experimentally-driven research deployed in multiple real Community Networks across Europe. Diversity in the characteristics of Community Networks and the need to use multiple or distributed testbeds, also including laboratory or...
Cloud computing has been applied in domestic and foreign digital library research. This paper analyzed the disadvantage of hospital digital library construction in our county. A better construction mode of hospital digital library based on cloud computing is proposed; we design an architecture of hospital digital library based on cloud computing, the steps of system implementation are introduced....
In a cloud computing environment, cloud users are competing for the same shared resources in order to run their applications or storage their data. In fact, cloud providers try to offer the necessary resources according to the users' demands giving the illusion of infinite resources. However, when these resources are insufficient to satisfy the users' requirements, conflicts may appear. Thus, it is...
This paper elaborates on the design of a prototype framework for the exploitation of virtual Network Functions (NFs) and virtual Network Resources (NRs) in a cloud-based network architecture. The proposed framework is based on a Marketplace approach, utilizing a centralized network architecture, where the exploitation of the available NFs/NRs is managed by a Brokerage Module. This Brokerage Module...
In this paper, we propose a novel approach for addressing both inter-cell interference and handover failure issues in dense WCDMA small cell deployments. This is achieved through an innovative scrambling allocation approach and an efficient spreading code allocation scheme that allow appropriate spatial reuse of resources. The proposed enhancements can be implemented in a centralised or distributed...
The explosive growth of wireless multimedia services skyrockets the demand for system capacity of the cellular communication network. The heterogeneous network (Hetnet) has been widely accepted as an effective wireless networking method to improve system capacity. However, multi-tier networking architecture and the great number of small cells coexisting with macrocell make the interference management...
One of the main subjects that are heavily studied in multi-robot domain is task allocation according to selected constraints and construct paths using these allocated tasks. In this paper a market-based task allocation method is proposed to allocate tasks according to their priorities and create paths for a mobile group in a known indoor environment. Proposed methodology is applied to an example with...
