Telecommunication Systems: How is Technology Change Creating New Opportunitie...Jeffrey Funk
These slides discuss how improvements in the data rates of wireline and wireless systems have and continue to occur. For wireline systems, these improvements are driven by the use of better glass fiber, lasers, amplifiers, and wavelength division multiplexing and there appears to be few limits to these improvements. For wireless systems, these improvements are primarily driven by the use of better ICs. As long as these improvements in ICs continue to occur, improvements in data rates along with improvements in the use of the frequency spectrum continue to be possible. Improvements in both wireless and wireline systems will also make new forms of Internet content possible. Furthermore, these improvements in ICs along with the improvements in MEMS that are discussed in a related set of slides are gradually making cognitive radio economically feasible. All of these improvements are creating various kinds of entrepreneurial opportunities. These slides are based on a forthcoming book entitled “Technology Change and the Rise of New Industries and they are the sixth session in a course entitled “Analyzing Hi-Tech Opportunities.”
This document discusses fiber to the home (FTTH) technology and implementation methods. It provides an overview of fiber optics, including the components and construction of fiber optic cable. Fiber offers huge bandwidth through a single fiber carrying data, voice, video and other services. While FTTH provides benefits over copper networks like higher reliability and capacity for future bandwidth growth, deployment costs tend to be high due to new infrastructure requirements. The document aims to standardize FTTH planning and implementation methods to reduce costs.
Optical fiber is the medium in which communication signals are transmitted from one location to another in the form of light guided through thin fibers of glass or plastic. These signals are digital pulses or continuously modulated analog streams of light representing information.
This document discusses fiber optic communication systems. It begins by introducing fiber optics as a major component of telecommunication infrastructure due to its high bandwidth capabilities and low signal attenuation. It then covers the basic building blocks of a fiber optic system including light sources, detectors, couplers and multiplexers. The document discusses the advantages of fiber optic systems such as long signal transmission distances, large bandwidth and small cable size. It also covers transmission windows, loss calculations and provides examples. In summary, the document provides an overview of the key concepts and components of fiber optic communication systems.
Fiber optics work by transmitting light through thin glass strands called optical fibers. Light travels down the core of the fiber by continuously reflecting off the cladding, surrounding the core. This total internal reflection allows light to travel long distances with little degradation. Fiber optics have advantages over copper wires including being less expensive to produce for long cable runs, requiring lower power transmitters, and being well-suited to carrying digital signals used in computer networks and telecommunications. Optical fibers are manufactured through heating and drawing preform glass cylinders into thin strands and testing the resulting fibers.

Mitigating effect of flickering and dimming in visible light communication us...Ramesh Patriotic
This paper proposes using MIMO techniques in visible light communication (VLC) systems to achieve high data transmission rates. It simulates various VLC system configurations (SISO, MISO, MIMO) using overlapping pulse position modulation. The results show that a MIMO system using an array of LEDs at the transmitter and receiver achieves much lower bit error rates than SISO or MISO systems as SNR increases. Specifically, at high SNR the MIMO system can provide bit error rates several orders of magnitude smaller than SISO. This confirms that MIMO is well-suited for VLC and can enable data rates of several hundred Mbps or even Gbps. The paper also evaluates modulation techniques for mitigating flickering and

IRJET- Implementation of Beamforming Techniques for Upcoming Wireless Communi...IRJET Journal
The document discusses various beamforming techniques that can be used for upcoming wireless communications systems to meet high data rate demands. It compares analog, digital, and hybrid beamforming techniques. Analog beamforming uses phase shifters to steer transmit and receive beams along propagation directions but does not provide channel state information. Digital beamforming is implemented through software algorithms but has hardware costs. Hybrid beamforming combines the advantages of analog and digital beamforming by providing channel state information while dynamically controlling antenna arrays. The document analyzes these techniques for applications such as massive MIMO and full duplex systems to enhance spectral efficiency and suppress interference.
Optical fibers transmit light between two ends of a flexible, transparent glass strand. They have a core surrounded by a cladding layer made of dielectric material that reflects light internally via total internal reflection. This keeps light signals confined within the core. Optical fibers come in single-mode, which transmits light straight down the core, and multi-mode, which allows multiple paths. They have wide applications in internet, cable TV, telephone networks, computer networking, medicine, lighting, inspections, military systems, and automotive technologies due to advantages like high bandwidth, immunity to electromagnetic interference, light weight, safety, and longer transmission distances compared to copper cables.
An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other.
The study of optical fibers is called fiber optics, which is part of applied science and engineering.

It discusses the basic components of an optical fiber transmission link including the transmitter, information channel, and receiver. It also describes the different parts of a fiber optic cable including the core, cladding, buffer, and jacket. Additionally, it covers the characteristics, operation, advantages, and disadvantages of optical fibers as well as the different fiber modes including single mode and multimode fibers. Finally, it compares step index and graded index fibers based on their refractive index profiles.

Task Performance Analysis in Virtual Cloud EnvironmentRSIS International
Cloud computing based applications are beneficial for
businesses of all sizes and industries as they don’t have to invest
a huge amount on initial setup. This way, businesses can opt for
Cloud services and can implement innovative ideas. But
evaluating the performance of provisioning (e.g. CPU scheduling
and resource allocation) policies in a real Cloud computing
environment for different application techniques is challenging
because clouds show dynamic demands, workloads, supply
patterns, VM sizes, and resources (hardware, software, and
network). User’s requests and services requirements are
heterogeneous and dynamic. Applications models have
unpredictable performance, workloads, and dynamic scaling
requirements. So a demand for a Simulation toolkit for Cloud is
there. Cloudsim is self-contained simulation framework that
provides simulation and modeling of Cloud-based application in
lesser time with lesser efforts. In this paper we tried to simulate
the task performance of a cloudlet using one data center, one
VM. We also developed a Graphical User Interface to
dynamically change the simulation parameters and show
simulation results.

This document summarizes a thesis submitted to Punjabi University for a Master of Technology degree in Computer Sciences and Engineering. The thesis, written by Kirandeep Kaur and supervised by Dr. Rajesh K. Bawa, proposes a novel flexible resource scheduling model for public clouds to avoid resource starvation. It introduces the problem of resource starvation in cloud computing environments and reviews existing resource scheduling mechanisms. The proposed model aims to simulate a public cloud environment using CloudSim and demonstrate that no user request will starve without proper resource allocation through a flexible scheduling approach that considers server load.

The concept of Genetic algorithm is specifically useful in load balancing for best virtual
machines distribution across servers. In this paper, we focus on load balancing and also on
efficient use of resources to reduce the energy consumption without degrading cloud
performance. Cloud computing is an on demand service in which shared resources, information,
software and other devices are provided according to the clients requirement at specific time. It‟s
a term which is generally used in case of Internet. The whole Internet can be viewed as a cloud.
Capital and operational costs can be cut using cloud computing. Cloud computing is defined as a
large scale distributed computing paradigm that is driven by economics of scale in which a pool
of abstracted virtualized dynamically scalable , managed computing power ,storage , platforms
and services are delivered on demand to external customer over the internet. cloud computing is
a recent field in the computational intelligence techniques which aims at surmounting the
computational complexity and provides dynamically services using very large scalable and
virtualized resources over the Internet. It is defined as a distributed system containing a
collection of computing and communication resources located in distributed data enters which
are shared by several end users. It has widely been adopted by the industry, though there are
many existing issues like Load Balancing, Virtual Machine Migration, Server Consolidation,
Energy Management, etc.

It has been used by researchers around the world for applications like evaluating resource allocation algorithms, energy-efficient management of data centers, and optimization of cloud computing environments and workflows.
This document provides an overview of several cloud simulation tools: CloudSim, CloudAnalyst, GreenCloud, and iCanCloud. CloudSim enables modeling and simulation of cloud computing infrastructures and applications. CloudAnalyst focuses on simulating large-scale cloud applications and studying their behavior under different deployment configurations using a graphical user interface. GreenCloud extends the NS2 network simulator to enable energy-aware cloud computing simulations at the packet level. iCanCloud allows modeling both existing and non-existing cloud architectures through a flexible hypervisor module and graphical interface to simulate distributed systems.
The document summarizes the cloud computing research of Alexandru Iosup and the PDS Group at TU Delft. Their research aims to evaluate the performance of virtualized cloud resources, analyze variability over long periods of time, and identify new applications that can utilize clouds. Key findings include that cloud performance can be below theoretical peak performance and that running scientific workloads in clouds may significantly reduce costs compared to other infrastructures.
PlanetLab is a global research network supporting network services development since 2003. It has over 1000 researchers using its 530 nodes across 717 sites to develop technologies like distributed storage, networking mapping, peer-to-peer systems, and distributed query processing. Cloud computing provides resources through services rather than direct access, while grid computing involves aggregating distributed resources for tasks like number crunching. The objective is to understand how PlanetLab can maintain benefits while preparing for the future, and to compare grid and cloud computing models in terms of assembly, offered services, and differences in scale. The conclusion is that cloud computing will become the main information technology as it realizes the vision of grid computing through standardization and dynamic pricing models.
This document discusses cross-cloud testing strategies for cloud computing applications. It proposes building an application prototype that can perform cross-cloud testing on multiple cloud platforms. The key aspects of existing approaches are that they do not test cloud-based software applications across different cloud environments. The proposed approach aims to develop a system that can test applications deployed on multiple independent cloud infrastructures to provide more flexibility and avoid vendor lock-in. Experimental results show the proposed approach can efficiently protect data during cross-cloud testing.

IRJET- Implementation of Cloud Energy Saving System using Virtual Machine...IRJET Journal
This document proposes a cloud energy saving system using virtual machine dynamic resource allocation on the OpenNebula platform. It aims to address the problems of high energy consumption and wasted idle resources in cloud computing. The system uses two methods: 1) autoscaling, which reallocates load between nodes based on process requirements to reduce response time and maximize throughput, and 2) live migration of VMs between hosts to power down idle machines. Two experiments are conducted to evaluate autoscaling performance and energy savings when adding and removing VMs on OpenNebula. The goal is to significantly reduce power consumption and wasted resources compared to traditional methods.
This course introduces students to cloud computing, artificial intelligence, and decentralized applications technologies. Students will learn about major cloud platforms and related services for computing, storage, networking, big data, and machine learning. They will combine these services to create intelligent autonomous networked solutions. The course also covers decentralized computing using Ethereum, smart contracts, and developing decentralized applications. Students will build their own projects combining cloud and decentralized technologies.
Hybrid Based Resource Provisioning in CloudEditor IJCATR
The data centres and energy consumption characteristics of the various machines are often noted with different capacities.
The public cloud workloads of different priorities and performance requirements of various applications when analysed we had noted
some invariant reports about cloud. The Cloud data centres become capable of sensing an opportunity to present a different program.
In out proposed work, we are using a hybrid method for resource provisioning in data centres. This method is used to allocate the
resources at the working conditions and also for the energy stored in the power consumptions. Proposed method is used to allocate the
process behind the cloud storage.
The document discusses cloud computing projects for final year students based on 2011-2012 IEEE papers. It provides an overview of cloud computing concepts like SaaS, PaaS, IaaS and virtualization. It then lists over 30 potential cloud computing project topics derived from recent IEEE papers covering areas like load balancing, security, storage management, and network management. It outlines the training and methodology that will be used for the projects including requirements gathering, design, development, testing and documentation review. Contact details are provided to inquire about these cloud computing final year projects.
End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.
