Integrated Models For Information Communication Systems And Networks: Design And Development

The text is divided into two broad sections. Section 1 deals with Networks and Information processes, while Section 2 is dedicated to chapters on Information Communication and Engineering. The first section consists of chapters one (1) through eight (8), with chapter one serving as an introductory piece. The second section is made up of the remaining eleven chapters from chapter nine to nineteen. Most of the chapters in this second part are in the field of communications with two in the area of artificial intelligence. In Chapter One, the principles of modeling are visited with a special bias to Information Communication Systems and Networks (ICSN). The basic rubrics of models, modeling, and simulation; an understanding of which is indispensible for the comprehension of subsequent chapters are expoused. Various fundamental terminologies, the knowledge of which is necessary for understding the concepts of models, modeling, and simulation, are explained. The contributing authors also shed some light on model structures and the methodological basis of formalizing complex system structures is discussed. The chapter concludes with recommendations from the authors on how to avoid the most common errors usually made by researchers in the process of model design which is that of losing track of the original problem statement as well as by embarking on actual model design without having enough requisite information about the modeled system. Chapter two reports on the numerical methods of multifractal analysis as it affects ICSN. In this very compelling chapter, the contributing authors present the theory of fractals and multifractals. A method based on multifractal data analysis at network layer level by means of Wavelet Transform Modulus Maxima (WTMM) is proposed for the detection of traffic anomalies in computer and telecommunication networks. Algorithm development methods for estimating multifractal spectrum are presented. The chapter also introduces WTMM as an informative indicator necessary to exploit the distinction of fractal dimensions on various parts of a given dataset. A novel approach based on the use of multifractal spectrum parameters is proposed for estimating queuing performance for the generalized multifractal traffic on the input of a buffering device, which shows that the multifractal character of traffic has significant impact on queuing performance characteristics. The contributing authors in Chapter three present the results of an extensive doctoral research thesis on a deterministic approach for resolving the switched LAN’s delay problem. In this interesting chapter, that actually challenges some basic assumptions met frequently in the literature, the authors assert the need for networks to be designed with specified maximum End-To-End delay since, if the maximum packet delay between any two nodes of a network is not known, it is impossible to provide a deterministic guarantee of worst case response times of packets’ flows.
