Principles of Ad Hoc Networking presents a systematic introduction to the fundamentals of ad hoc networks.  An ad-hoc network is a small network, especially one with wireless or temporary plug-in connections. Typically, some of the network devices are part of the network only for the duration of a communications session or, in the case of mobile or portable devices, while in some close proximity to the rest of the network. These networks can range from small and static systems with constrained power resources to larger-scale dynamic and mobile environments. Wireless ad hoc networks facilitate numerous and diverse applications for establishing survivable dynamic systems in emergency and rescue operations, disaster relief and intelligent home settings.Principles of Ad Hoc Networking: Introduces the essential characteristics of ad hoc networks such as: physical layer, medium access control, Bluetooth discovery and network formation, wireless network programming and protocols.Explains the crucial components involved in ad-hoc networks in detail with numerous exercises to aid understanding.Offers key results and merges practical methodologies with mathematical considerations.Principles of Ad Hoc Networking will prove essential reading for graduate students in Computer Science, Electrical Engineering, Applied Mathematics and Physics as well as researchers in the field of ad hoc networking, professionals in wireless telecoms, and networking system developers.Check out  www.scs.carleton.ca/~barbeau/pahn/index.htm for further reading, sample chapters, a bibliography and lecture slides!

AdHoc Networks are wireless, self-organizing systems formed by co-operating nodes, within communication range of each other which form temporary n- works. Their topology is dynamic, decentralized, and ever-changing, and the nodes may move around arbitrarily. The last few years have witnessed a wealth ofresearchideasonAdHocnetworkswhicharemovingrapidlyintoimplemented standards. Mobile computing, particularly wireless-enabled mobile computing, covers a large area of applications in mobile computing environments, networking, c- municationdevicesandsystems.Thisconferenceexposesexperimentalaswellas theoretical research in adhoc, mobile and wireless networks. The range of topics covered includes management of power consumption, architectures and pro- cols, quality of service, and security. The aim of the conference was to provide a unique opportunity for researchers and students in industry and academia to participate at an annual forum and share their research results and experiences. This conference followed the ?rst successful conference (held at the Fields - stituteinTorontoduringSeptember20-21oflastyear),andwasheldattheH- iday Inn, Midtown in Montreal during October 8-10, 2003.It was co-sponsored by the Mobile Computing and Networking Research Laboratory (LARIM) of the ' Ecole Polytechnique de Montr' eal, theSchool of Computer Science (SCS) of C- leton University, MITACS (Mathematics of Information Technology and C- plex Systems), and the Association for Computing Machinery (ACM).

The third international workshop on AD-HOC NetwOrks and Wireless was held in the downtown Vancouver facilities of Simon Fraser University. The ?rst ADHOC-NOW was held in 2002 at the Fields Institute in Toronto and the s- ond in 2003 in Montreal. Its purpose is to create a collaborative forum between Mathematicians,ComputerScientistsandEngineersforresearchintheemerging ?eld of ad-hoc networks. The number of submissions exceeded all expectations this year. Over 150 papers were submitted of which 22 regular and 8 short papers were accepted for presentation and inclusion in the conference proceedings.

This textbook presents a survey of research on boolean functions, circuits, parallel computation models, function algebras, and proof systems. Its main aim is to elucidate the structure of "fast" parallel computation. The complexity of parallel computation is emphasized through a variety of techniques ranging from finite combinatorics, probability theory and finite group theory to finite model theory and proof theory. Nonuniform computation models are studied in the form of boolean circuits; uniform ones in a variety of forms. Steps in the investigation of non-deterministic polynomial time are surveyed as is the complexity of various proof systems. The book will benefit advanced undergraduates and graduate students as well as researchers in the field of complexity theory.

This book constitutes the refereed proceedings of the 6th International Conference on Ad-Hoc Networks and Wireless, ADHOC-NOW 2007, held in Morelia, Mexico, in September 2007. The 21 revised full papers were carefully reviewed and selected from 50 submissions. The papers are organized in topical sections on routing, topology control, security and privacy, protocols, as well as quality of service and performance.

The foundations of computational complexity theory go back to Alan Thring in the 1930s who was concerned with the existence of automatic procedures deciding the validity of mathematical statements. The first example of such a problem was the undecidability of the Halting Problem which is essentially the question of debugging a computer program: Will a given program eventu­ ally halt? Computational complexity today addresses the quantitative aspects of the solutions obtained: Is the problem to be solved tractable? But how does one measure the intractability of computation? Several ideas were proposed: A. Cobham [Cob65] raised the question of what is the right model in order to measure a "computation step" , M. Rabin [Rab60] proposed the introduction of axioms that a complexity measure should satisfy, and C. Shannon [Sha49] suggested the boolean circuit that computes a boolean function. However, an important question remains: What is the nature of computa­ tion? In 1957, John von Neumann [vN58] wrote in his notes for the Silliman Lectures concerning the nature of computation and the human brain that . . . logics and statistics should be primarily, although not exclusively, viewed as the basic tools of 'information theory'. Also, that body of experience which has grown up around the planning, evaluating, and coding of complicated logical and mathematical automata will be the focus of much of this information theory. The most typical, but not the only, such automata are, of course, the large electronic computing machines.

This book constitutes the refereed proceedings of the 6th International Conference, FUN 2012, held in June 2012 in Venice, Italy. The 34 revised full papers were carefully reviewed and selected from 56 submissions. They feature a large variety of topics in the field of the use, design, and analysis of algorithms and data structures, focusing on results that provide amusing, witty but nonetheless original and scientifically profound contributions to the area.

As well as highlighting potentially useful applications for network analysis, this volume identifies new targets for mathematical research that promise to provide insights into network systems theory as well as facilitating the cross-fertilization of ideas between sectors. Focusing on financial, security and social aspects of networking, the volume adds to the growing body of evidence showing that network analysis has applications to transportation, communication, health, finance, and social policy more broadly. It provides powerful models for understanding the behavior of complex systems that, in turn, will impact numerous cutting-edge sectors in science and engineering, such as wireless communication, network security, distributed computing and social networking, financial analysis, and cyber warfare.The volume offers an insider’s view of cutting-edge research in network systems, including methodologies with immense potential for interdisciplinary application. The contributors have all presented material at a series of workshops organized on behalf of Canada’s MITACS initiative, which funds projects and study grants in ‘mathematics for information technology and complex systems’. These proceedings include papers from workshops on financial networks, network security and cryptography, and social networks. MITACS has shown that the partly ghettoized nature of network systems research has led to duplicated work in discrete fields, and thus this initiative has the potential to save time and accelerate the pace of research in a number of areas of network systems research.
