Capacity Estimation for Vehicle-to-Grid Frequency Regulation Services With Smart Charging Mechanism

Due to various green initiatives, renewable energy will be massively incorporated into the future smart grid. However, the intermittency of the renewables may result in power imbalance, thus adversely affecting the stability of a power system. Frequency regulation may be used to maintain the power balance at all times. As electric vehicles (EVs) become popular, […]

Spectral Efficiency and Throughput Enhancement by Full-Duplex D2D Communication in Mobile Clouds

In this paper we consider downlink resource sharing for full-duplex (FD) device-to-device (D2D) communications underlying cellular network. We aim to maximize the system throughput and increase the spectral efficiency in wireless communications by integrating the concepts of D2D and FD communications. We formulate a throughput maximization problem and then based on its constraints we analytically derive […]

Industrial application development exploiting IoT vision and model driven programming

In recent years there has been a huge discussion about the IoT (Internet of Things) concept, and even more about IoT within industrial environment. The real IoT is a network of devices with local intelligence (sensors, lights, gas pumps, HVAC systems), which shares access & control mechanisms to push and pull status and command information from the networked world. […]

A Socio-Physical Approach to Systemic Risk Reduction in Emergency Response and Preparedness

This paper proposes a socio-physical approach that considers jointly the interaction and integration of the social and physical views of a system to improve emergency response and preparedness. This is accomplished through a reduction of systemic risk, which refers to a risk that could be greater than the sum of the risks of the individual […]

An enhanced router based queuing policy providing better fairness to real-time data transfers in Internet

Forwarding and delivery in IP based internet is a best effort service. IP being a connectionless forwarding mechanism, it may drop the packets at the time of congestion. This may affect the services in internet as it is not able to deliver the packet with sufficient Quality of service (QOS). The reliability mechanism adopted by […]

Innovative propagation mechanism for inter-chip and intra-chip communication

SoC (System on chip) technology has rapidly developed in recent years, stimulating emerging research areas such as investigating the efficacy of wireless network interconnection within a single chip or between multiple chips. However the design of the on-chip antenna faces the challenge of obtaining high radiation efficiency and transmission gain due to conductive loss of the silicon […]

Wi-Fi-based hierarchical Wireless Networked Control Systems

This paper proposes a novel architecture for a hierarchical Wireless Networked Control System (WNCS). It consists of three cascaded workcells each containing 30 sensors, 30 actuators and one controller. The wireless communication protocol used is IEEE 802.11g with multicasting. The hierarchy of the system is such that the lowest level is that of the sensors […]

Successful realization of Non-Foster circuits for wide-band antenna applications

Non-Foster circuits (NFCs) are promising for numerous microwave and antenna applications because they are not limited by the gain-bandwidth product. Although NFCs can be very useful in many applications, successful realization of these circuits is difficult because they suffer from several issues, including losses, noise, and instability. As a consequence, an accurate and efficient design […]

Prospects for electric vehicles technology with renewable energy sources in a Smart-Grid environment – An introduction

This article is focused on issues concerning electric vehicle technology, linked to the use of renewable sources and their incorporation into the concept of modern automated (unattended) traffic systems – ATS. This concept creates an ideal environment for the generation and development of so-called “Smart Grids”. Deployment of electric vehicles (herein abbreviated to EV) and […]

Traffic Engineering Using Multi-protocol Label Switching (MPLS) for Delay Sensitive Traffic

Traffic engineering is one of the most challenging topics in Multi-protocol Label switching (MPLS) which deal with controlling traffic in such a way so that optimized path can be achieved with respect to network utilization and efficient data delivery. Internet traffic use Interior Gateway Protocol (IGP) to send traffic over the network using the shortest […]
