Book excerpt: Until recently, most network design techniques employed a bottom-up approach with lower protocol layer mechanisms affecting the development of higher ones. This approach, however, has not yielded fascinating results in the case of wireless distributed networks. Addressing the emerging aspects of modern network analysis and design, Evolutionary Dynamics of Complex Communications Networks introduces and develops a top-bottom approach where elements of the higher layer can be exploited in modifying the lowest physical topology—closing the network design loop in an evolutionary fashion similar to that observed in natural processes. This book provides a complete overview of contemporary design approaches from the viewpoint of network science and complex/social network analysis. A significant part of the text focuses on the classification and analysis of various network modification mechanisms for wireless decentralized networks that exploit social features from relevant online social networks. Each chapter begins with learning objectives and introductory material and slowly builds to more detailed analysis and advanced concepts. Each chapter also identifies open issues, while by the end of the book, potential research directions are summarized for the more interested researcher or graduate student. The approach outlined in the book will help network designers and administrators increase the value of their infrastructure without requiring any significant additional investment. Topics covered include: basic network graph models and properties, cognitive methods and evolutionary computing, complex and social network analysis metrics and features, and analysis and development of the distinctive structure and features of complex networks. Considering all aspects of modern network analysis and design, the text covers the necessary material and background to make it a suitable source of reference for graduate students, postdoctoral researchers, and scientists

Book excerpt: We use minority game model to investigate evolutionary dynamics in complex networks of adaptive agents competing for limited resources. We show that the dynamics and the associated phase structures critically depend on the underlying network organizations, and evolution is a key mechanism for the emergence of high-order coordination among the networked agents. A non-growing random directed network admits a clear phrase transition from a stable or quot;criticalquot; state to a quot;chaoticquot; state. In contrast, no such phrase transition has been detected in a growing directed network; Instead, it permits stable or quot;criticalquot; dynamics for all the connectivity. The dynamics of a scale-free directed network is found sensitive to its connectivity if a small fraction of link reversal is allowed in the network: The evolutionary dynamics exhibits a gradual phase transition from the stable (or quot;criticalquot;) state to the quot;chaoticquot; regime with increase of the connectivity number K; this suggests that the scale-free directed network is vulnerable to a small fraction of quot;errorsquot; in its network organization. The underlying sources for the emergence of these dynamics are the organizations of the networks and can be understood with a descendant clusters theory. Evolution dramatically enhances the performance of a system in a stable or quot;criticalquot; regime, but has no effect on a system in quot;chaoticquot; state; such attribute can be empowered to typify the dynamics of a complex network. The impact of evolution on system efficiency lies in its ability in reducing quot;crowdednessquot; of agents' strategies and can be explained by a crowd-anticrowd theory.

Book Synopsis Complex Dynamics in Communication Networks by : Ljupco Kocarev

Download or read book Complex Dynamics in Communication Networks written by Ljupco Kocarev. This book was released on 2005-06-13. Available in PDF, EPUB and Kindle. Book excerpt: Computer and communication networks are among society's most important infrastructures. The internet, in particular, is a giant global network of networks without central control or administration. It is a paradigm of a complex system, where complexity may arise from different sources: topological structure, network evolution, connection and node diversity, or dynamical evolution. The present volume is the first book entirely devoted to the new and emerging field of nonlinear dynamics of TCP/IP networks. It addresses both scientists and engineers working in the general field of communication networks.

Book Synopsis Dynamics On and Of Complex Networks by : Niloy Ganguly

Download or read book Dynamics On and Of Complex Networks written by Niloy Ganguly. This book was released on 2009-04-14. Available in PDF, EPUB and Kindle. Book excerpt: This self-contained book systematically explores the statistical dynamics on and of complex networks having relevance across a large number of scientific disciplines. The theories related to complex networks are increasingly being used by researchers for their usefulness in harnessing the most difficult problems of a particular discipline. The book is a collection of surveys and cutting-edge research contributions exploring the interdisciplinary relationship of dynamics on and of complex networks. Topics covered include complex networks found in nature—genetic pathways, ecological networks, linguistic systems, and social systems—as well as man-made systems such as the World Wide Web and peer-to-peer networks. The contributed chapters in this volume are intended to promote cross-fertilization in several research areas, and will be valuable to newcomers in the field, experienced researchers, practitioners, and graduate students interested in systems exhibiting an underlying complex network structure in disciplines such as computer science, biology, statistical physics, nonlinear dynamics, linguistics, and the social sciences.
