James Gross - Böcker

The Wagner Act of 1935 (later the Wagner-Taft-Hartley Act of 1947) was intended to democratize vast numbers of American workplaces: the federal government was to encourage worker organization and the substitution of collective bargaining for employers' unilateral determination of vital work-place matters. Yet this system of industrial democracy was never realized; the promise was \u0022broken.\u0022 In this rare inside look at the process of government regulation over the last forty-five years, James A. Gross analyzes why the promise of the policy was never fulfilled. Gross looks at how the National Labor Relations Board's (NLRB) policy-making has been influenced by the President, the Congress, the Supreme Court, public opinion, resistance by organized employers, the political and economic strategies of organized labor, and the ideological dispositions of NLRB appointees. This book provides the historical perspective needed for a reevaluation of national labor policy. It delineates where we are now, how we got here, and what fundamental questions must be addressed if policy-makers are to make changes consistent with the underlying principles of democracy.

A crucial step during the design and engineering of communication systems is the estimation of their performance and behavior; especially for mathematically complex or highly dynamic systems network simulation is particularly useful.This book focuses on tools, modeling principles and state-of-the art models for discrete-event based network simulations, the standard method applied today in academia and industry for performance evaluation of new network designs and architectures.The focus of the tools part is on two distinct simulations engines: OmNet++ and ns-3, while it also deals with issues like parallelization, software integration and hardware simulations. The parts dealing with modeling and models for network simulations are split into a wireless section and a section dealing with higher layers. The wireless section covers all essential modeling principles for dealing with physical layer, link layer and wireless channel behavior. In addition, detailed models for prominent wireless systems like IEEE 802.11 and IEEE 802.16 are presented.In the part on higher layers, classical modeling approaches for the network layer, the transport layer and the application layer are presented in addition to modeling approaches for peer-to-peer networks and topologies of networks. The modeling parts are accompanied with catalogues of model implementations for a large set of different simulation engines.The book is aimed at master students and PhD students of computer science and electrical engineering as well as at researchers and practitioners from academia and industry that are dealing with network simulation at any layer of the protocol stack.
