A novel approach for the calculation of transient fault current contributions from capacitive network components in HVDC cable networks during pole-to-ground faults is presented in this paper. Analytic approximations considering the skin effect and the resulting distortion of the waveshape of the fault surge are proposed. Only fault current contributions from capacitive components, such as […]
The originality of this paper consists in proposing a model that can be used to simulate the manner in which companies interoperate in cooperative supply chain networks. The objective is to develop a model that enables the analysis of the impact of business interoperability on the performance of cooperative supply chain networks. The analysis of […]
This paper discusses the need for the integration of storage systems on transmission networks having renewable sources, and presents a tool for energy storage planning. The tool employs robust optimization to minimize the investment in storage units that guarantee a feasible system operation, without load or renewable power curtailment, for all scenarios in the convex […]
Tunable sparse network coding (TSNC) with various sparsity levels of the coded packets and different feedback mechanisms is analysed in the context of data gathering applications in multi-hop networks. The goal is to minimize the completion time, i.e., the total time required to collect all data packets from the nodes while maintaining the per packet […]
Multi-gigabit millimeter wave wireless communications for 5G: from fixed access to cellular networks
With the formidable growth of various booming wireless communication services that require ever increasing data throughputs, the conventional microwave band below 10 GHz, which is currently used by almost all mobile communication systems, is going to reach its saturation point within just a few years. Therefore, the attention of radio system designers has been pushed […]
A novel coplanar waveguide (CPW)-fed dual-band dual-mode patch antenna for on-/off-body communications is proposed. The proposed antenna, which comprises a T-shaped patch with parasitic patches, a circular patch, and a CPW feed line, has dimensions of 30 mm × 45 mm × 3.2 mm. The proposed antenna operates in the 2.4 GHz ISM band (2.4 […]
An advanced patient-centric bedside monitoring system design based on wireless body area sensor networks and telemedicine technologies is proposed in this paper where each patient uses sensors with wireless transmission capabilities and transmit the physiological signals within a larger advanced network, which is connected to a secured section of the public network. This work intends […]
In the SDN approach, the control and data planes are separated to enable programmability and interoperability, the control plane being logically centralized. Scalability and reliability are key properties for the SDN control plane. In WAN deployments, it is already envisioned as physically distributed to span across the networks and avoid single point of failure. In […]
In this paper we propose and investigate load-dependent load balancing for resilient OpenFlow networks. The objective is to spare extra capacity for the primary path of a traffic aggregate (flow) by accommodating excess traffic on its backup path. The contribution of the paper is manyfold. We explain existing OpenFlow features for traffic monitoring and dynamic […]
Network protection against link failure is required to allow packets to reach the destination with minimal packet loss when a failure occurs. When a link fails, traffic that attempts to use the failed link is interrupted. Typically, routers in the network discover the failure and find a new route to bypass the failed link. Alternatively, […]
