A Mobile Ad Hoc Network (MANET) is a mobile, wireless network that does not necessitate a pre-existing infrastructure. The routing infrastructure needs to be established in a distributed, self-organized way. Many routing protocols for MANETs have been proposed, and some evaluating work has been conducted. The large number of the proposed routing protocols and evaluations makes it difficult to keep track of the development and to get an overview of the strengths and weaknesses of routing protocols. The author Daniel Lang analyses evaluation techniques from the past and describes common...

The use of wireless communication systems has risen greatly in the last ten years. Wireless standards such as WLAN and WPAN make it possible to establish point to point connections without the need of any fixed infrastructure, creating ad hoc networks to exchange data and voice. The topology of the network created by nodes can change randomly when the nodes move, making routing a big challenge. In response, Jose Ayub Gonzalez Garrido has developed a caching strategy which will allow nodes to efficiently adapt their cache to reconfigurations in the network. This cache mechanism is implemented...

"Divide et impera!" - The concept of subdividing complex monolithic tasks into simpler units of work is neither new nor IT-specific. But the basic idea behind grid computing would well be communicated by this ancient roman strategy. Today's IT-systems are sized for their peak-load. Pooling all available computing resources into a single set of services that can easily be scaled and shared among different workloads, immediately reacting to dynamically changing needs, would be an appropriate way of overcoming economic or technical constraints and limitations. The latest development is...

Performance Analysis of Queuing and Computer Networks develops simple models and analytical methods from first principles to evaluate performance metrics of various configurations of computer systems and networks. It presents many concepts and results of probability theory and stochastic processes.

After an introduction to queues in computer networks, this self-contained book covers important random variables, such as Pareto and Poisson, that constitute models for arrival and service disciplines. It then deals with the equilibrium M/M/1/∞queue, which is the simplest queue that...

The protocol definition of IPv6 was developed some years ago, but the deployment in real-world networks is a long time coming. The reasons are manifold - the exhaustion of the IPv4 address space has not occured yet and the practical use of IPv6 is a big question mark. But at some point network engineers will have to deal with the new protocol in their environments. The author Florian Frotzler provides an introduction on the IPv6 protocol, several interworking strategies between IPv4 and IPv6 and large scale international projects that deal with the implementation of the new protocol. Based on...

Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Network Coding recently has been presented as a technique to increase the throughput in multicast networks. Most of the work done on the topic considers an error free transmission and few works have taken into account the errors due to the nature of the wireless channel. In this work we propose a scheme for a wireless network using ideas...

An immensely important area, this introduction to computer networking covers everything from systems linked by telephone lines to tightly coupled networks of processors using high speed lines, and the correspondingly broad range of techniques that are needed. The emphasis lies on understanding the principles involved, rather than being bound to specific systems or protocols that may rapidly become out of date. A detailed discussion of standards and systems is given where they are widely accepted and likely to be long-lasting. In particular the ARPANET and OSI standards are explained. The...

Algebraic Theory of Automata Networks investigates automata networks as algebraic structures and develops their theory in line with other algebraic theories. Automata networks are investigated as products of automata, and the fundamental results in regard to automata networks are surveyed and extended, including the main decomposition theorems of Letichevsky, and of Krohn and Rhodes. The text summarizes the most important results of the past four decades regarding automata networks and presents many new results discovered since the last book on this subject was published. Several new methods...

This book constitutes the thoroughly refereed joint post-proceedings of the three International Workshops on Grid Middleware, CoreGrid 2006, the UNICORE Summit 2006, and the Workshop on Petascale Computational Biology and Bioinformatics, held in Dresden, Germany, in August/September 2006, in conjunction with Euro-Par 2006, the 12th International Conference on Parallel Computing.

Establishing the foundation of Collaborative Networks The need for computer-assisted collaboration, which originally manifested decades ago in manufacturing to establish small business-oriented networks of organizations in forms of supply chains or extended enterprises, is by now extended into a large number of other areas. While today production and service provision constitute the main areas of application for Collaborative Networks (CNs) worldwide, during the last decade virtual scientific laboratories, inter-enterprise collaborative engineering, crisis management, virtual institutes and...
