This book was released on 2000 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The remarkable growth of wireless communication networks and the increasing demand for diverse and reliable services over the air interface have created the need for robust and survivable design and management of wireless networks and its performance analysis. This research develops a configurable teletraffic simulator for survivability analysis of wireless access networks under the normal as well as faulty conditions. The framework consists of subscriber traffic layer and radio traffic layer for user location, mobility, and network model and resource management schemes. The concept of a geographical data set has been introduced and processed with trip estimation technique for representing spatial environmental information. Overlapping coverage area has been selected as cell-site architecture to improve the resilience of the mobile networks. Dynamic load-balancing protocols have been proposed as a means to increase mobile network survivability and compared with a commonly referenced scheme. The framework has been implemented with C++ and is modeled after cellular communication networks in aspects of network functionality and measurement of real teletraffic characteristics. The applicability of the simulated framework is demonstrated in a case study of fault traffic conditions in traffic hot-spot and failed channel group.

This book was released on 2003-09-11 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Competition within the telecommunications companies is growing fiercer by the day. Therefore, it is vital to ensure a high level of quality and reliability within all telecommunications systems in order to guard against faults and the failure of components and network services. Within large scale systems such quality and reliability problems are ever higher. The metrics of Quality and Reliability have to date only been available in journals and technical reports of companies which have designed or produced major parts of systems used in large applications. This book provides a self-contained treatment enabling the reader to be able to produce, define and utilise the metrics of Quality and Reliability required for the design and implementation of a large application such as a world class event as the Olympic Games. An additional outcome is that this book can be used as a guide for producing an ISO standard for large scale Systems such as the Olympic Games. * Provides presentations of techniques used for solving quality and reliability problems in telecommunications networks replete with illustrations of their applications to real-world services and world class events * Individual chapters written by respective international experts within their fields This will prove highly informative for Practising engineers, researchers and telecommunications professionals, academics and graduate students in telecommunications, standards bodies and organisations such as ISO.

Available in PDF, EPUB and Kindle. Book excerpt: The ever-increasing adoption and usage of mobile devices have created explosive demand for wireless data services. In spite of the great efforts made to expand the capabilities of wireless infrastructures and mobile devices, performance issues caused by resource contention keep arising. This calls for optimized resource management solutions which not only efficiently utilize network and device resources, but consistently optimize the performance under various scenarios. The problem is highly challenging considering the inherent resource sharing feature of wireless medium and the unpredictable dynamics in wireless environments. In this dissertation, we present a two-tier dynamic-oriented resource management solution for wireless mobile systems, which involves several novel techniques corresponding to different layers of the network architecture. The first tier is a scheme designed to optimize network infrastructure of wireless networks. We study the cross-layer resource management problem which covers multiple layers from the transport layer to the medium access layer. We present two techniques that are operated on different time scales. One technique relies on Capacity Space Projection to form a virtual capacity space, which contains both the slow time scale and the fast time scale capacity signals. Then the cross-layer resource allocation becomes an optimization problem over the virtual capacity space. Using the other technique, we can investigate the risk imposed by unpredictable fast-time scale and perform risk-benefit analysis by introducing a penalty function into the optimization framework. The second tier is an application layer management scheme applied to the ecosystem consisting of mobile terminals and remote computational resources. This scheme aims to improve user experience by minimizing the energy consumption during a task execution. This is achieved by a mobile application offload system that intelligently migrates the computation-intensive tasks from a mobile application to the back-end server. We present energy profiling models and a runtime decision solver to enable cost-effective offloading in dynamic environments. The two tiers employ distinct resource management strategies, however, they are closely related in the layered architecture of mobile wireless systems.

Download or read book High Performance Modelling and Simulation for Big Data Applications written by Joanna Kołodziej and published by Springer. This book was released on 2019-03-25 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book was prepared as a Final Publication of the COST Action IC1406 “High-Performance Modelling and Simulation for Big Data Applications (cHiPSet)“ project. Long considered important pillars of the scientific method, Modelling and Simulation have evolved from traditional discrete numerical methods to complex data-intensive continuous analytical optimisations. Resolution, scale, and accuracy have become essential to predict and analyse natural and complex systems in science and engineering. When their level of abstraction raises to have a better discernment of the domain at hand, their representation gets increasingly demanding for computational and data resources. On the other hand, High Performance Computing typically entails the effective use of parallel and distributed processing units coupled with efficient storage, communication and visualisation systems to underpin complex data-intensive applications in distinct scientific and technical domains. It is then arguably required to have a seamless interaction of High Performance Computing with Modelling and Simulation in order to store, compute, analyse, and visualise large data sets in science and engineering. Funded by the European Commission, cHiPSet has provided a dynamic trans-European forum for their members and distinguished guests to openly discuss novel perspectives and topics of interests for these two communities. This cHiPSet compendium presents a set of selected case studies related to healthcare, biological data, computational advertising, multimedia, finance, bioinformatics, and telecommunications.

This book was released on 2021-06-25 with total page 1496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Running a small business provides opportunity for greater success, increased growth, and potentially the chance to move to the global business arena, yet also much more risk. Small businesses not only have less employment, but also less annual revenue than a regular-sized business. With the growth of large corporations and chain businesses, it has become harder to maintain the survival of a small business. The COVID-19 pandemic has also brought more pressure onto the already unsteady survival of small businesses, due to forced closures, decreased agility, fewer technological innovations, and smaller customer bases. The Research Anthology on Small Business Strategies for Success and Survival offers current strategies for small businesses that can be utilized in order to maintain equal footing during challenging times. With the proper strategies available to small business owners, small businesses could not only survive, but also excel despite the environment that surrounds them. Covering topics including decision management, new supportive technologies, sustainable development, and micro-financing, this text is ideal for small business owners, entrepreneurs, startup companies, family-owned and operated businesses, restaurateurs, local retailers, managers, executives, academicians, researchers, and students.
