Book Description
Mobile wireless ad-hoc networks (MANETs) are being designed to be a key element in future battlefield communications, as well as a supplement to cellular networks. As a consequence of rapid changes in the topology of the network, routing packets in MANETs is a challenging task that has attracted considerable attention. However a comprehensive performance evaluation of routing protocols remains an open problem. This dissertation proposes a novel methodology for the performance evaluation of routing protocols for MANETs. The method is based on a "Divide and Conquer" approach and it provides a systematic and disciplined way to evaluate the performance of routing protocols. The full routing system is decomposed into components (subsystems). Performance models are developed for each component. Then, the performance model of the full system is the interconnection of the performance models of the components. The component based approach makes practical the performance evaluation of routing protocols, by allowing researchers to reuse a subset of the previous developed models to evaluate the performance of new ideas.

Book Description
During recent years a great deal of progress has been made in performance modelling and evaluation of the Internet, towards the convergence of multi-service networks of diverging technologies, supported by internetworking and the evolution of diverse access and switching technologies. The 44 chapters presented in this handbook are revised invited works drawn from PhD courses held at recent HETNETs International Working Conferences on Performance Modelling and Evaluation of Heterogeneous Networks. They constitute essential introductory material preparing the reader for further research and development in the field of performance modelling, analysis and engineering of heterogeneous networks and of next and future generation Internets. The handbook aims to unify relevant material already known but dispersed in the literature, introduce the readers to unfamiliar and unexposed research areas and, generally, illustrate the diversity of research found in the high growth field of convergent heterogeneous networks and the Internet. The chapters have been broadly classified into 12 parts covering the following topics: Measurement Techniques; Traffic Modelling and Engineering; Queueing Systems and Networks; Analytic Methodologies; Simulation Techniques; Performance Evaluation Studies; Mobile, Wireless and Ad Hoc Networks, Optical Networks; QoS Metrics and Algorithms; All IP Convergence and Networking; Network Management and Services; and Overlay Networks.

Book Description
This book presents revised versions of tutorial lectures given at the IEEE/CS Symposium on modeling, analysis, and simulation of computer and telecommunication systems held in Orlando, FL, USA in October 2003. The lectures are grouped into three parts on performance and QoS of modern wired and wireless networks, current advances in performance modeling and simulation, and other specific applications of these methodologies. This tutorial book is targeted to both practitioners and researchers. The practitioner will benefit from numerous pointers to performance and QoS issues; the pedagogical style and plenty of references will be of great use in solving practical problems. The researcher and advanced student are offered a representative set of topics not only for their research value but also for their novelty and use in identifying areas of active research.

Book Description
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.

Book Description
Mobile ad hoc networks (MANET) are becoming increasingly popular, particularly in the realm of sensor networks. Most of the ongoing research of these networks is centered on protocol development and data delivery characteristics, particularly in the areas of throughput and latency. But in the realm of wireless networks, a new metric needs to be considered, one that takes into consideration the power efficiency across the wireless network. This thesis addresses this need by defining a new network performance metric that incorporates aspects of both power efficiency and data throughput. The new metric is a reflection of the performance of the routing protocol being evaluated for a particular network scenario. Comparing the metric values for different network routing protocols allow for the optimal network routing protocol for the particular network scenario to be identified. Wireless nodes have a finite amount of energy to operate with, and when that energy is depleted, the node dies and no longer performs its intended functions. In order to maintain a functioning MANET for longer periods of time, the network as a whole needs to consider power efficiency for optimal network lifetime. Some optimization techniques include transmission power, data compression, and even the network protocols used for network connectivity. Several of these techniques are discussed, but this research focuses more on the network routing protocols and the power footprints associated with them. While other researchers are developing power-aware routing algorithms, often by augmenting existing protocols, this thesis develops a methodology of comparing the overall network performance of the routing protocols used for a particular network scenario. Data is gathered through network simulations with ns-3, an open source network simulator. Four common routing protocols are evaluated against several network scenarios. Data collected per simulation includes the network lifetime and data throughput statistics. The data is analyzed in order to find the optimal routing protocol for the particular network scenario. Rather than creating yet another power-aware routing algorithm, this thesis develops a value-function based approach for measuring network performance that incorporates both power efficiency and data throughput.
