A Study of the Effect of Physical Environment on the Survivability Analysis of Mobile Networks


Book Description

ABSTRACT: Due to the remarkable growth of subscribers in cellular systems and mobile communication networks, users expect the same reliable services over the air interface during all operating conditions. This is creating the need to design more robust and survivable wireless access networks. The design of survivable networks requires performance analysis in the wake of failure. However, research has shown that the effectiveness of network analysis is highly dependent on the underlying system modes that are used. This study develops the effects of population distribution and transportation infrastructure on various channel allocation protocols under normal, hot spot and failed conditions. For this we select three geographic areas (small, medium and large cities) and perform various simulation runs by varying different geographic data sets under all above stated conditions and compare the performance of channel assignment protocols in terms of new call blocking, forced termination and handover activity. The results illustrate the extent to which incorporation of empirical data from the physical environment affects the conclusions that are drawn with respect to mobile network performance and survivability analysis.

Reliability, Survivability and Quality of Large Scale Telecommunication Systems


Book Description

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.




Research Anthology on Small Business Strategies for Success and Survival


Book Description

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.

Educating the Student Body


Book Description

Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
