Available in PDF, EPUB and Kindle. Book excerpt: A method for delay distribution analysis of Window Random-Access algorithms is presented. The window size is allowed to vary during the operation of the algorithm. It is shown that the quantities of interest in the computation of the delay distribution, can be related to the solution of appropriate infinite systems of linear equations. Once the constants and the coefficients of the unknowns of a system are determined, bounds on the solution can be developed by applying previously developed methodologies. The method is applied to the delay distribution analysis of the Capetanakis Window Random-Access algorithm and the Part-and-Try algorithms, both under binary feedback. (Author).

This book was released on 1988 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many communication applications with time constraints (e.g., transmission of packetized voice messages), a critical performance measure is the percentage of messages which are transmitted within a given amount of time after their generation at the transmitting station. In this talk we present a random access algorithm (RAA) suitable for time-constrained applications. Performance analysis demonstrates that significant message delay improvement is attained, at the expense of minimal traffic loss. We also consider the case of noisy channels. The noise effect appears at erroneously observed channel feedback. Error sensitivity analysis shows that the proposed random access algorithm is insensitive to feedback channel errors. Window Random Access Algorithms (RAAs) are considered next. These algorithms constitute an important subclass of Multiple Access Algorithms (MAAs); they are distributive and they attain high throughput and low delays by controlling the number of simultaneously transmitting users.

Available in PDF, EPUB and Kindle. Book excerpt: A simple full sensing window random access algorithm is analyzed in the presence of the limit Poisson user model. The throughput of the algorithm is 0.43, and its delay and resistance to channel errors characteristics are superior to those induced by the Capetanakis window algorithm. In addition, the simple operations of the algorithm, in conjunction with its regenerative properties, allow for the computation and evaluation of the output traffic interdeparture distribution. The latter is needed in the evaluation of interacting systems which use the algorithm for their internal transmissions.

This book was released on 1987 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider the Channel Multiple-Access problem for messages with strict delay constraints. The constraints are represented by an upper bound on the transmission delays. For this problem, and for binary collision-noncollision feedback per slot, we present a simple full sensing window Random-Access algorithms. We analyze the algorithm and we compute the fraction of maintained traffic and the expected per successfully transmitted packet delay, for various input Poisson intensities and various values of the bound on the transmission delays.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless technologies and applications are becoming one of the fastest growing and most promising areas in recent years. To accommodate data transmission by multiple stations sharing the scarce wireless bandwidth, a medium access control (MAC) protocol plays a crucial role in scheduling packet transmission fairly and efficiently. The emerging wireless networks, such as ad-hoc networks, sensor networks or mesh networks, are mostly multi-hop based and in distributed manner, which brings a lot of problems and challenges in designing fine-tuned MAC protocols tailored for modern wireless network. In this book, the authors give complete and in-depth overviews to the classic medium access control algorithms and the related protocols, as well as their applications in various wireless data networks especially the most successful Wireless Local Area Networks (WLAN). The book consists of three major parts. Part I of this book, including Chapters 1-7, is emphasising on the fundamentals of medium access control algorithms and protocols. Chapter 1 provides an introduction to the wireless networks, such as overview of wireless networks, problems and challenges of the wireless networks, and the classifications of MAC protocols as well as the performance metrics. Chapter 2 introduces important collision resolution algorithms applied in medium access controls, for example, the splitting algorithm and the backoff algorithm. Chapter 3 reviews the hybrid access control algorithms that combine both contention and allocation schemes. A series of important collision avoidance schemes are introduced in Chapters 4-7 respectively, with a specific design goal covered in each chapter. Chapter 4 focuses on the multi-channel MAC protocols for collision avoidance; Chapter 5 introduces the concepts of power control and power management in medium access control and how they can be applied in MAC protocol design; Chapter 6 presents how to provide Quality-of- Service (QoS) to multimedia wireless networks, in either centralised or distributed manner; and Chapter 7 explains how the smart antennas can be applied in the medium access control to provide high channel throughput and low packet collision.
