Download or read book Collision Avoidance and Resolution Multiple Access written by Rodrigo Garcés and published by . This book was released on 1999 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple-access interference constitutes a major cause of throughput degradation in wireless networks. The focus of this thesis is the design and analysis of medium access control protocols that mitigate multiple access interference by resolving collisions of small control packets used to avoid the collision of much larger data packets. An upper bound on the average cost of resolving collisions using a deterministic tree-splitting algorithm is derived. This bound is then applied to the compute the average channel utilization in a fully connected network with a large number of stations. Under light-load conditions., collision avoidance and resolution (CARMA) protocols achieve the same average throughput as floor acquisition multiple access (FAMA) protocols. It is also shown that, as the arrival rate of RTSs increases, the throughput achieved by CARMA protocols is close to the maximum throughput that any FAMA protocol can achieve when propagation delays and the control packets used to acquire the floor are much smaller than the data packet trains sent by stations.

Download or read book Sender and Receiver initiated Multiple Access Protocols for Ad hoc Networks written by Asimakis E. Tzamaloukas and published by . This book was released on 2000 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the medium access control (MAC) layer. Many MAC protocols for wireless networks proposed or implemented to date are based on collision-avoidance handshakes between sender and receiver. The key objective of collision-avoidance handshakes is reducing or eliminating the collision of data packets from a source at any given receiver due to interference from packets from other sources. In the vast majority of these protocols, including the IEEE 802.11 standard, the handshake is sender-initiated, in that the sender asks the receiver for permission to transmit using a short control packet, and transmits only after the receiver sends a short clear-to-send notification. There are two main objectives in this work: analyze the effect of reversing the collision-avoidance handshake as a way to improve the performance of MAC protocols under any conditions in the network, and design MAC protocols that provide correct floor acquisition without carrier sensing or code pre-assignment. We show that receiver-initiated collision-avoidance MAC protocols not only outperform any sender-initiated ones, but also guarantee collision-free data transmission and seamless support for mobility by using simple, low-cost wireless radios. We study the effect of persistent carrier sensing in receiver- as well as sender-initiated MAC protocols. We extend our work to multi-channel radios and introduce novel collision-avoidance MAC protocols that eliminate the need for carrier sensing and code pre-assignment, and improve the utilization of the medium in the presence of unicast, multicast and broadcast traffic.

Available in PDF, EPUB and Kindle. Book excerpt: Communication is one of the most important aspects of the business world. Professional men and women use communication for getting ahead, resolving interpersonal conflicts and working collaboratively with others to achieve unified goals. Since communication is such a necessary business component, business people must familiarize themselves with communication techniques that will be most effective for them and their professional counterparts. The importance of communication skills can be seen when good, quality communication occurs that prevents misunderstandings, miscommunication and conflict. It produces productive work and performance which ultimately impacts the company's bottom line. Business Communication is any communication used to promote a product, service, or organization - with the objective of making sale. In business communication, message is conveyed through various channels of communication including internet, print (publications), radio, television, outdoor, and word of mouth. There is a good chance that you may not know what kind of listener you are. After all, until the topic arises, most people do not tend to think about the issue. So now is the time to think about it. There are different types of listeners out there, and learning about some of the different ways that people listen may help you use that information to improve your listening skills. This book covers all the aspects of Business Communication. It is hoped that this book will meet the requirements of teaching, training and development programme. Besides, the text will provide valuable guidance to any individual who is keen on improving his/her communication skills.

Download or read book Medium Access Control in Wireless Networks written by Hongyi Wu and published by Nova Publishers. This book was released on 2008 with total page 662 pages. 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.

Download or read book Wireless Multimedia Network Technologies written by Rajamani Ganesh and published by Springer Science & Business Media. This book was released on 2006-04-18 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of invited papers that were presented at the Ninth IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, September 5-8, 1998, Boston, MA. These papers are meant to provide a global view of the emerging third-generation wireless networks in the wake of the third millennium. Following the tradition of the PIMRC conferences, the papers are selected to strike a balance between the diverse interests of academia and industry by addressing issues of interest to the designers, manufacturers, and service providers involved in the wireless networking industry. The tradition of publishing a collection of the invited papers presented at the PIMRC started in PIMRC’97, Helsinki, Finland. There are two benefits to this tradition (1) it provides a shorter version of the proceedings of the conference that is more focused on a specific theme (2) the papers are comprehensive and are subject of a more careful review process to improve the contents as well as the presentation of the material, making it more appealing for archival as a reference book. The production costs of the book is subsidized by the conference and the editors have donated the royalty income of the book to the conference.
