Real-Time Low Voltage Network Monitoring—ICT Architecture and Field Test Experience
Traditionally, distribution network monitoring has been focused on primary substations (i.e., high voltage/medium voltage level), whereas low voltage (LV) network has not been monitored at all. With rapid growth and penetration of distributed energy resources in LV grids, there is growing interest in extending the real-time monitoring to LV level. The framework program FP7 European Project INTEGRIS proposes an […]
A LiFePO4 battery discharge simulator for EV applications — Part 2: Developing the battery simulator
This paper, the second of the series on developing a LiFePO4 (LFP) battery discharge simulator for EV applications, presents an approach for developing the battery simulator. After the optimal battery model was established, in the first paper, the main drawbacks of battery simulator are addressed and a new strategy is proposed. This strategy uses neural networks (NN) for online estimation of the battery […]
Ctherm: An Integrated Framework for Thermal-Functional Co-simulation of Systems-on-Chip
This paper presents therm, an integrated framework for cycle-accurate thermal and functional evaluation of systems-on-chip. The presented framework enables accurate characterization of thermal behaviour by generating detailed physical models for components based on input specifications, and simulating them within a tightly integrated co-simulation platform with an embedded thermal simulator. Therm’s fine-grained modelling approach yields 70% higher […]
Cost Estimation of Parallel Constrained Producer-Consumer Algorithms
Cost estimation is crucial in the performance modeling of parallel algorithms and allocation of computational resources on distributed systems. This paper presents a novel methodology for estimating the cost of constrained producer-consumer (CPC) algorithms. In CPC algorithms, the computation is performed by classes of nodes (tasks), separated in time. The methodology combines data flow analysis […]
A raptor enabled data carousel for enhanced file delivery and QoS in 802.11 multicast networks
802.11 WLANs do not provide any standardized solution for reliable data multicast. Multicast packets are delivered to multiple clients as a simple broadcast service without support for Automatic Repeat Request. Hence, a fixed low speed (robust) transmission mode is generally used to improve the reliability of multicast files. However, this results in the inefficient use […]
An ME-PC Enhanced HDMR Method for Efficient Statistical Analysis of Multiconductor Transmission Line Networks
An efficient method for statistically characterizing multiconductor transmission line (MTL) networkssubject to a large number of manufacturing uncertainties is presented. The proposed method achieves its efficiency by leveraging a high-dimensional model representation (HDMR) technique that approximates observables (quantities of interest in MTL networks, such as voltages/currents on mission-critical circuits) in terms of iteratively constructed component functions of […]
SCUMG: Secure Code Update for Multicast Group in Wireless Sensor Networks
Securing code update is essential for military and health care applications. The functionalists of the sensor nodes in military and health monitoring region depend on their environmental conditions. The sensor nodes will be divided into different multi cast groups based on their location. For each multi cast group a different code update will be sent. […]
Platform for Multiagent Application Development Incorporating Accurate Communications Modeling
Multiagent systems are widely recognized as a method of choice for realization of distributed time-critical applications for the smart grid. However, no general solutions have been proposed for the difficult task of system development and validation, ready for deployment, which would fully account for the underlying communication network performance. We propose a novel platform designed for this […]
Developing a coherent global view for post disaster situation awareness using opportunistic network
Situational awareness is a critical component in a post-disaster recovery operation for assessment of needs and identification of available resources at different parts of a disaster-affected area. This information, in turn, may help the relief agencies to appropriately coordinate, manage and channelize their resources. A major hindrance in developing such global situational awareness is the […]
Rate, power and carrier-sense threshold coordinated management for high-density IEEE 802.11 networks
Nowadays, trying to obtain better coverage and performance, and allowed by the low-hardware prices, it is common to deploy a large number of IEEE 802.11 devices in offices, meeting rooms or auditoriums configuring the so called high-density networks. In such a scenario, the shared nature of the transmission medium causes interference problems. Some physical-layer- and link-layer-adaptation […]
