Electric vehicles and local energy storage will be widely deployed. Internet technology will be utilized to transform the power grid into an energysharing inter-grid. To prepare for the future, a smart grid with intelligent periphery, or smart GRIP, is proposed. The building blocks of GRIP architecture are called clusters and include an energy-management system （EMS）-controlled transmission grid in the core and distribution grids, micro-grids, and smart buildings and homes on the periphery; all of which are hierarchically structured. The layered architecture of GRIP allows a seamless transition from the present to the future and plug-and-play interoperability. The basic functions of a cluster consist of （1） dispatch, （2） smoothing, and （3） mitigation. A risk-limiting dispatch methodology is presented; a new device, called the electric spring, is developed for smoothing out fluctuations in periphery clusters; and means to mitigate failures are discussed.展开更多

Nowadays, billions of smart objects are immersed in the environment, sensing, interacting, and cooperating with each other to enable efficient services. When we think about IoT, classification is a major challenge particularly if our technology is international level applicable. So, this limitation needs clear and deep analysis of the existing classification matrixes and gives some future directions depending on the different researches in the area. The paper surveys the current state-of-art in the classification of IoT. First, we try to explain commonly existing classification matrixes;Second, cooperation of different methods defending on classification matrixes used. Then analyses challenges that IoT faced from classification angle and finally we give some direction for future IoT classification.展开更多

The full implementation of the Future Internet concept implies in the necessity to operate among heterogeneous technology platforms with continuity of QoS (Quality of Service), what leads to the necessity of an innovative business model to support it and new technical mechanisms of vertical handover to ensure the QoS continuity required and expected by final users but, mainly, perceived by them. An innovative business model that requires innovative QoS continuity mechanisms must consider technical and commercial interoperation among many telecommunication services providers, nationally and internationally based. This interaction demands clear rules to be followed by every player along the telecommunication services chain,i.e., it demands a set of regulation acts to guide them and allow their viability.展开更多

This paper proposes a secure mobility support mechanism in e Xpressive Internet Architecture(XIA),a new FIA currently under development as part of the US National Science Foundation's(NSF) program. Utilizing the natural features of ID/locator decoupling and versatile routing in XIA, a general mechanism to support host mobility is proposed. Exploiting the self-certifying identifier, a secure binding update protocol to overcome the potential threats introduced by the proposed mobility support mechanism is also given. We demonstrate that our design in XIA outperforms IP based solutions in terms of efficiency and flexibility. We also outline our initial design to illustrate one derivative benefit of an evolvable architecture:mobility support customizability with no sacrifice of architectural generality.展开更多

In order to deal with these issues, a national research project, supported by the prestigious National Basic Research Program (also called the "973 program") of China, was launched in May 2007. This project adopts a clean-slate approach and aims to design a novel future Internet that not only inherits the merit of the Internet today but also overcomes the drawbacks of the current Internet. In this paper, we make an overview of this project with a focus on its objectives, basic ideas, and progresses. Although this is a basic research project, its success will bring significant benefits to China as well as all other countries in the world.展开更多
