For the European project DISCUS, we study the deployment of active nodes to connect all customers in different countries via (long-reach) passive optical networks. In particular, we investigate design parameters such as the resilience strategy, the maximum node size, and the maximum signal reach. We evaluate the resulting node distributions and survivable fiber route connections […]
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.
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 […]
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 […]
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 […]
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 […]
We propose a joint multi-layer planning algorithm for IP over flexible optical networks, and use it, to compare the performance of joint as opposed to sequential multi-layer network planning in terms of spectrum and cost.
The new paradigm of molecular communication aims to utilize biological components and systems for developing communication systems. One promising candidate for molecular communication is the use of bacteria to carry information between different nanomachines. However, there is a lack of connection between molecular communication and the design of nanomachines for payload delivery. Utilizing molecular communication […]
This study presents a new methodology for modelling and handling with aggregated harmonic loads and linear loads in the harmonic power flow analysis. This method, so-called variable load method, can be used in balanced and unbalanced systems and for deterministic and stochastic studies. The main types of harmonic loads and their participation coefficients inside the […]
In this paper, we consider the case where two communicating cognitive radio users are not near to each other or have no direct line of sight(LOS). Some secondary users don’t need the entire spectrum available to them because of their traffic demand being low. If we are able to use this unused spectrum to relay […]
