Available in PDF, EPUB and Kindle. Book excerpt: A family of medium access control protocols for single-channel packet radio networks is specified and analyzed. These protocols are based on a new channel access discipline called floor acquisition multiple access (FAMA), which consists of both carrier sensing and a collision-avoidance dialogue between a source and the intended receiver of a packet. Control of the channel (the floor) is assigned to at most one station in the network at any given time, and this station is guaranteed to be able to transmit one or more data packets to different destinations with no collision with transmissions from other stations. The minimum length needed in control packets to acquire the floor is specified as a function of the channel propagation time. The medium access collision avoidance (MACA) protocol proposed by Karn and variants of CSMA based on collision avoidance are shown to be variants of FAMA protocols when control packets last long enough compared to the channel propagation delay. The throughput of FAMA protocols is analyzed and compared with the throughput of non-persistent CSMA. This analysis shows that using carrier sensing as an integral part of the floor acquisition strategy provides the benefits of MACA in the presence of hidden terminals, and can provide a throughput comparable to, or better than, that of non-persistent CSMA when no hidden terminals exist.

Available in PDF, EPUB and Kindle. Book excerpt: Medium access control for devices that share a particular medium is a fundamental problem in communications networks. We present a new protocol for medium access control called floor acquisition multiple access (FAMA). Floor acquisition protocols guarantee data packets are received without collisions from other packets. We present FAMA protocols for both single and multiple channel devices operating in ad-hoc packet radio networks. We present analytical and simulation results for FAMA protocols.

Available in PDF, EPUB and Kindle. Book excerpt: The performance of the FAMA-NCS protocol in ad-hoc networks is analyzed. FAMA-NCS (for floor acquisition multiple access with non-persistent carrier sensing) guarantees that a single sender is able to send data packet free of collisions to a given receiver at any given time. FAMA-NCS is based on a three-way handshake between sender and receiver in which the sender uses non-persistent carrier sensing to transmit a request-to-send (RTS) and the receiver sends a clear-to-send (CTS) that lasts much longer than the RTS to serve as a "busy tone" that forces all hidden nodes to back off long enough to allow a collision-free data packet to arrive at the receiver. It is shown that FAMA-NCS performs better than ALOHA, CSMA, and all prior proposals based on collision avoidance dialogues (e.g., MACA, MACAW, and IEEE 802.11 DFWMAC) in the presence of hidden terminals. Simulations experiments are used to confirm the analytical results.

Book excerpt: The convergence of wireless communication and the Internet is one of the strongest emerging markets in the telecommunications industry. This book consists of a compilation of papers on key issues related to 3G and 4G wireless communications and wireless access to next generation Internet (NGI). Included in Multiaccess, Mobility and Teletraffic for Wireless Communications: Volume 5 are new results on space-time access schemes that can dramatically increase the achievable bit rates of wireless systems, perhaps approaching bandwidth efficiencies in the order of 10 bits/s/Hz. The book also considers broadband wireless access to NGI. Effective management of radio resources in wireless systems is necessary for high spectral efficiency and to support mobility. This book treats issues relating to handoff and channel assignment in cellular frequency reuse systems. In order to achieve quality of service (QoS) expectations in a dynamically changing wireless environment, effective error and QoS control protocols are needed. To guarantee fairness in the access to resources, medium access control (MAC) protocols are needed. Optimization of network resources traffic and mobility models are also needed, along with effective call admission control strategies. All of these topics are covered herein. Finally, this book considers future 3G and 4G wireless systems and highlights the critical challenges that must be overcome to make these systems a commercial reality. Multiaccess, Mobility and Teletraffic for Wireless Communications: Volume 5 is an important book for researchers, students and professionals working in the area of wireless communications and mobile computing.

Available in PDF, EPUB and Kindle. Book excerpt: Collision avoidance and resolution multiple access (CARMA) protocols are presented and analyzed. These protocols use a floor acquisition multiple access (FAMA) strategy based on carrier sensing, together with collision resolution of floor requests (RTS) based on a tree-splitting algorithm. For analytical purposes, an upper bound is derived for the average costs of resolving collisions of floor requests using the tree-splitting algorithm. This bound is then applied to the computation of the average channel utilization in a fully connected network with a large number of stations. Under light-load conditions, CARMA protocols achieve the same average throughput as FAMA protocols. It also is 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 if propagation delays and the control packets used to acquire the floor are much smaller than the data packet trains sent by stations. Simulation results validate the simplifying approximations made in the analytical mode. The authors' analysis results indicate that collision resolution makes floor acquisition multiple access much more effective.

This book was released on 2013-03-09 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unrelenting growth of wireless communications continues to raise new research and development problems that require unprecedented interactions among communication engineers. In particular, specialists in transmission and specialists in networks must often cross each other's boundaries. This is especially true for CDMA, an access technique that is being widely accepted as a system solution for next-generation mobile cellular systems, but it extends to other system aspects as well. Major challenges lie ahead, from the design of physical and radio access to network architecture, resource management, mobility management, and capacity and performance aspects. Several of these aspects are addressed in this volume, the fourth in the edited series on Multiaccess, Mobility and Teletraffic for Wireless Communications. It contains papers selected from MMT'99, the fifth Workshop held on these topics in October 1999 in Venezia, Italy. The focus of this workshop series is on identifying, presenting, and discussing the theoretical and implementation issues critical to the design of wireless communication networks. More specifically, these issues are examined from the viewpoint of the impact each one of them can have on the others. Specific emphasis is given to the evolutionary trends of universal wireless access and software radio. Performance improvements achieved by spectrally efficient codes and smart antennas in experimental GSM testbeds are presented. Several contributions address critical issues regarding multimedia services for Third-Generation Mobile Radio Networks ranging from high rate data transmission with CDMA technology to resource allocation for integrated Voice/WWW traffic.

Book excerpt: Ad hoc networks, which include a variety of autonomous networks for specific purposes, promise a broad range of civilian, commercial, and military applications. These networks were originally envisioned as collections of autonomous mobile or stationary nodes that dynamically auto-configure themselves into a wireless network without relying on any existing network infrastructure or centralized administration. With the significant advances in the last decade, the concept of ad hoc networks now covers an even broader scope, referring to the many types of autonomous wireless networks designed and deployed for a specific task or function, such as wireless sensor networks, vehicular networks, home networks, and so on. In contrast to the traditional wireless networking paradigm, such networks are all characterized by sporadic connections, highly error-prone communications, distributed autonomous operation, and fragile multi-hop relay paths. The new wireless networking paradigm necessitates reexamination of many established concepts and protocols, and calls for developing a new understanding of fundamental problems such as interference, mobility, connectivity, capacity, and security, among others. While it is essential to advance theoretical research on fundamental and practical research on efficient policies, algorithms and protocols, it is also critical to develop useful applications, experimental prototypes, and real-world deployments to achieve an immediate impact on society for the success of this wireless networking paradigm.

Book excerpt: Increasingly, modern medicine relies on so called traditional or ancient medical knowledge. Holistic practices such as adhering to proper diet, observing rules for appropriate behavior, and administering medical preparations are coupled with the latest technology and methods to treat the whole patient. In light of this trend, there is much to be gained from understanding of one of the oldest medical systems still in existence. Tibetan Medicinal Plants provides you a detailed analysis of how Tibetan plants are used in this centuries old system. The book opens with a summary of Tibetan medicine and covers the various habitats in which the plants are found. The main part of this volume encompasses 60 monographs listed by the Tibetan plant name. Each monograph consists of several chapters addressing different topics related either to the Tibetan or the Western approach. Most of the monographs contain a description of the macroscopic and microscopic characteristics of the used plant parts, and anatomical features of 76 plants are provided. Each monograph presents an overview of the known chemical constituents and pharmacological properties of each plant and describes their use in Tibetan medicine. In contrast to other publications on Tibetan medicine, where translations of the Tibetan terms are given in other languages, this book treats the Tibetan word as a technical term, keeps the Tibetan term and explains its meaning, lessening confusion by reducing the number of translations. Traditional Tibetan medicine has been in existence for centuries. Curative practices existed in the prebuddistic era, and the art of healing developed more than 2500 years ago. Tibetan Medicinal Plants provides a comprehensive overview of all plant types, thus making it easier to grasp the Tibetan concept. It gives you a comprehensive look at this centuries old science.
