Feasibility Study of Quasi-Optical MIMO Antennas for Radiative Near-Field Links

This article presents a feasibility study of single feed per beam quasi-optical (QO) antennas for enabling incoherent multiple-input multiple-output (MIMO) array front-end architectures at 270 GHz. The objective is to reach ultrafast and radiated energy efficient point-to-point (PtP) wireless links by exploiting the multimode capacity of...

Learning-based resilience guarantee for multi-UAV collaborative QoS management

Unmanned and intelligent technologies are the future development trend in the business field. It is of great significance for the connotation analysis and application characterization of massive interactive data. Particularly, during major epidemics or disasters, how to provide business services safely and securely is crucial. Specifically,...

Blind Spots of Objective Measures: Exploiting Imperceivable Errors for Immersive Tactile Internet

Tactile Internet (TI) enables the transfer of human skills over the Internet, enabling teleoperation with force feed-back. Advancements are being made rapidly at several fronts to realize a functional TI soon. Generally, TI is expected to faithfully reproduce operator's actions at the other end, where a robotic arm emulates it while providing...

GUI for System Dimensioning and QO Channel Analysis of Pulsed Pico-second Radar

THz time-domain systems driven by photoconductive antennas (PCAs) promise a bandwidth of the order of hundreds of GHz. This characteristic can be utilized to build see-through radars with sub-mm resolution and a field of view comparable to the current mm-wave radars at a relatively low cost. These radars can solve the issues in the field of...

A Quasi-Oppositional Method for Output Tracking Control by Swarm-Based MPID Controller on AC/HVDC Interconnected Systems with Virtual Inertia Emulation

This paper presents a comprehensive evaluation of the effect of quasi oppositional - based learning method utilization in output tracking control through a swarm-based multivariable Proportional-Integral-Derivative (SMPID) controller, which is tuned by a novel performance index based on the step response characteristics in multi-input multi...

EdgeBOL: Automating energy-savings for mobile edge AI

Supporting Edge AI services is one of the most exciting features of future mobile networks. These services involve the collection and processing of voluminous data streams, right at the network edge, so as to offer real-time and accurate inferences to users. However, their widespread deployment is hampered by the energy cost they induce to...

A model to measure Quality of Experience (QoE) of Online Social Gaming

Understanding the impact of socialization on player Quality of Experience (QoE), which is an important aspect in Online Social Games (OSG), has become a hot research topic. Of the various ways of measuring the player's QoE, in this thesis, we propose and make use of the model used to extract objective data from the players in combination with...

Important Issues and Economic Study of Ship DC Distribution System with Variable-Speed Diesel Generator

In a traditional AC distribution system, the synchronous frequencies of the generators are coupled with the system frequency, and thus the diesel engines are kept at a constant speed. In a Dynamic Positioning (DP) vessel such as a Platform Supply Vessel (PSV), the diesel engines sometimes work at the partial load condition. The efficiency of...

Implementing Link-state Update Policies for Quality of Service Routing

This thesis describes the implementation of available bandwidth link-state update policies for Quality of Service routing. Periodic, threshold-based and class-based policies are described and implemented in a QoS router testbed, using Quagga and its OSPF-API for low-level communications. The implementation is thoroughly tested using unit tests...

Impairment-Aware QoS Routing in Translucent Optical Networks

Wavelength-division-multiplexed (WDM) optical networks are commonly used to trans- port huge amount of tra±c in long-haul and metro/regional networks. In these networks, the optical signals deteriorate due to the physical impairments they encounter as they traverse multiple links. This necessitates regeneration of the signals at the intermediate...

Flow-based Networking and Quality of Service

During the past two decades the Internet has been widely deployed and integrated into the society, radically altering the way people communicate and exchange information. Although the Internet was intended as a research network between few a institutions in the United States, it has grown to take a central role in day-to-day communications and...

Quality of Service Routing in the Internet. Theory, Complexity and Algorithms

The Internet consists of many network elements that direct packets on the correct path leading towards the destination. This process of finding and following a path to the destination is called routing. Routing is not infallible and packets may get lost: the current Internet cannot give any quality guarantees regarding the packets it transports....
