Evaluating the Impact of Registered Power Zones Incentive on Wind Systems Integration in Active Distribution Networks

For the better integration of distributed and renewable generation, new investments in innovative distribution networks, such as active distribution networks and smart grids (SGs), are required. Regulators should decide what incentives are desirable to create a flexible economic regulatory framework that can drive distribution system operators to invest in innovation and in active distribution networks. […]

1.4 mA (70 mV) peak-to-peak drive of 1.25 Gb/s frequency modulated laser for WDM coherent access networks

A new laser suitable for access-systems with FM efficiency up to 7 GHz/mA and negligible amplitude modulation is presented. It enables 1.25/2.5 Gb/s operations with extremely low driving signals: 70 mVpk-pk and 250 mVpk-pk respectively.

The Optimal Node Placement for Long Belt Coverage in Wireless Networks

The optimal node placement for a very large plane without boundary effect has been proven to be the regular triangular-lattice pattern in 1939. However, the regular triangular-lattice placement may not be optimal in a long belt with an upper and lower boundary. This paper proposes an optimal node deployment pattern to minimize the number of […]

Minimal virtualized-elastic-regenerator placement and least congestion resources assignment for translucent elastic optical networks

A virtualized-elastic-regenerator (VER) is a promising solution for efficiently regenerating various superchannels in elastic optical networks. We propose an effective heuristic for calculating minimal VER placement, routing, and least congestion resources assignment.

QoS-based WebRTC access to an EPS network infrastructure

This paper describes a method to support QoS using WebRTC-based Clients integrated in mobile devices conformed to 3GPP Rel. 8 Public Land Mobile Network infrastructure. To enrich the experience for mobile customers using this upcoming technology, the article focuses on the merging of the technical capabilities arising from both the Evolved Packet System inherent QoS […]

Advanced Network Management Systems: A Risk-Based AC OPF Approach

This paper presents a risk-based advanced distribution network management system (NMS) aimed at maximizing wind energy harvesting while simultaneously managing congestion and voltages. The NMS allows the adoption of multi-minute control cycles so the volume of actions from on-load tap changers (OLTCs) and distributed generation (DG) plants can be reduced while effectively catering for the […]

Multicore Fiber Enabled WSDM Optical Access Network with Centralized Carrier Delivery and RSOA Based Adaptive Modulation

We proposed and experimentally demonstrated a wavelength-space division multiplexing (WSDM) optical access network architecture with centralized optical carrier delivery utilizing multicore fibers (MCFs) and adaptive modulation based on reflective semiconductor amplifier (RSOA). In our experiment, five of the outer cores are used for undirectional downstream (DS) transmission only, while the remaining outer core is utilized […]

A Method for the Trajectory Privacy Protection Based on the Segmented Fake Trajectory under Road Networks

In recent years, LBS (Location-Based Service)have been widely used. According tithe historical location of user, location service providers may analyze the user’s interests, health and other personal privacy. The traditional k-anonymous protection method for trajectory mainly depends on the European space but not consider the road networks. In this paper, we proposed a method for […]

Architecting space communication networks under mission demand uncertainty

NASAs Space Network has been a successful program that has provided reliable communication and navigation services for three decades. As the third generation of satellites is being launched, alternatives to the current architecture of the system are being studied in order to improve the performance of the system, reduce its costs and facilitate its integration […]

Reduction of Four Wave Mixing by employing circular polarizers in DWDM optical networks

Next generation optical communication networks demand the use of the lower channel spacing and high input power in Wavelength Division Multiplexing (WDM) systems to achieve higher data rates. However, decreasing channel spacing and increasing input power create nonlinear effects including Four Wave Mixing (FWM). In this paper a method has been introduced in which alternative […]
