The evolution of the Internet has triggered a significant activity exploring new architectures among which the concept of Information-Centric-Networks (ICN) has emerged. Considering the various ICN solutions, Content-Centric Networking (CCN) is the one that received most attention. The design of CCN is progressing albeit many important issues still deserve a careful analysis and design. In this paper,...
In this paper, we explore recent Device-to-Device (D2D) research efforts and review their suitability to safety-critical Internet of Vehicles (IoV) applications, such as cooperative or autonomous driving. Typical to the IoV environment is the high node mobility along with strict Quality of Service (QoS) requirements, especially in terms of delay and reliability. In addition, IoV applications require...
A key element to realizing the smart energy grid of the future is the deployment of an efficient and reliable information network. An intelligent combination of wired networks (the Internet), wireless networks and power line communication networks can be used to deliver control and application messages generated by the smart grid. Integration of these three network types is non-trivial due to the...
The Cloud Computing wave consolidates the on-demand provisioning of configurable virtual machines. Recent projects have proposed the extension of the original IaaS paradigm to provide dynamic virtual networks to interconnect virtual IT resources, composing Virtual Infrastructures (VIs). In this new scenario, users with different objectives and expectations can rent dynamically provisioned virtual...
The increasing growth of the global Internet making the shortcomings of its unstructured topology and distributed routing algorithm are exposed more rapidly. To design a controllable, scalable and manageable backbone network with a simple, efficient architecture is very imperative. Among many topologies, Tree topology which has a natural hierarchical structure and explicit end-to-end transmission...
In this work, we study the traffic adjustment over multipath network in the presence of both inelastic and elastic traffic flows. The characteristics of these two types of traffic differ significantly. Hence, earlier approaches that focus on homogeneous scenarios with a single traffic type are not directly applicable. We formulate a new traffic adjustment problem based on time series prediction and...
The purpose of this study is to understand how willing consumers are in terms of using the FON platform to share their bandwidth. Based on the recommendations by Homans (1958), Blau (1964), and Emersons (1972),"social exchange theory" and Blau (1964), "economic exchange theory" and "innovation diffusion theory" were adopted as the basis for the discussion on the willingness...
In this work, using a game-theoretic approach, cost-sensitive mechanisms that lead to reliable Internet-based computing are designed. In particular, we consider Internet-based master-worker computations, where a master processor assigns, across the Internet, a computational task to a set of potentially untrusted worker processors and collects their responses. Several game-theoretic models that capture...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
Optical networks are currently widely employed to support a variety of telecommunications and other applications. In order to provide the increased bandwidth needed by the existing and emerging applications, optical networks rely extensively on wavelength division multiplexing (WDM). In these networks, WDM is not only used to satisfy capacity requirements, but it can be also exploited to offer advanced...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
E-business organizations commonly trade services together with quality of service (QoS) guarantees that are often dynamically agreed upon prior to service provisioning. Violating agreed QoS levels incurs penalties and hence service providers agree to QoS requests only after assessing the resource availability. Thus the system should, in addition to providing the services: (i) monitor resource availability,...
Global computing uses Internet-connected PCs volunteered by their owners. These PCs are diverse, volatile, and error-prone. Sophisticated scheduling methods commonly applied in grid computing may not be sufficiently scalable and flexible for global computing environments. This paper shows that it is possible to classify global computing hosts based on simple metrics such as availability and reliability,...
