This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "While Packet Fair Queueing (PFQ) algorithms provide both bounded delay and fairness in wired networks, they cannot be applied directly to wireless networks. The key difficulty is that in wireless networks sessions can experience location-dependent channel errors. This may lead to situations in which a session receives significantly less service than it is supposed to, while another receives more. This results in large discrepancies between the sessions' virtual times, making it difficult to provide both delay-guarantees and fairness simultaneously. Our contribution is twofold. First, we identify a set of properties, called Channel-condition Independent Fair (CIF), that a Packet Fair Queueing algorithm should have in a wireless environment: (1) delay and throughput guarantees for error-free sessions, (2) long term fairness for error sessions, (3) short term fairness for error-free sessions, and (4) graceful degradation for sessions that have received excess service. Second, we present a methodology for adapting PFQ algorithms for wireless networks and we apply this methodology to derive a novel algorithm based on Start-time Fair Queueing, called Channel-condition Independent packet Fair Queueing (CIF-Q), that achieves all the above properties. To evaluate the algorithm we provide both theoretical analysis and simulation results."

Download or read book Compressive Sensing for Wireless Networks written by Zhu Han and published by Cambridge University Press. This book was released on 2013-06-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compressive sensing is a new signal processing paradigm that aims to encode sparse signals by using far lower sampling rates than those in the traditional Nyquist approach. It helps acquire, store, fuse and process large data sets efficiently and accurately. This method, which links data acquisition, compression, dimensionality reduction and optimization, has attracted significant attention from researchers and engineers in various areas. This comprehensive reference develops a unified view on how to incorporate efficiently the idea of compressive sensing over assorted wireless network scenarios, interweaving concepts from signal processing, optimization, information theory, communications and networking to address the issues in question from an engineering perspective. It enables students, researchers and communications engineers to develop a working knowledge of compressive sensing, including background on the basics of compressive sensing theory, an understanding of its benefits and limitations, and the skills needed to take advantage of compressive sensing in wireless networks.
Download or read book Resource Allocation in Next Generation Wireless Networks written by Wayne Li and published by Nova Publishers. This book was released on 2006 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Next generation wireless and mobile communication systems are rapidly evolving to satisfy the demands of various network users. Due to the great success and enormous impact of IP networks, high-speed transmission is now possible for both indoor and outdoor wireless systems, internet access and web browsing have become the ruling paradigm for next generation system. It is envisioned that new generation wireless networks and hand-held terminals will support a wide variety of multimedia services such as multimedia web browsing, video and news on demand, mobile office system, stock market information, and so on, to mobile users anywhere, anytime in an uninterrupted and seamless way with low-powered handsets. The characteristics of wireless links, as well as the desire to maintain connectivity while on the move, offer significant challenges to provisioning quality of service and the related performance is of central interest. Since the resources (such as time, frequency and code) in the wireless segments of such networks are very limited, over-dimensioning the network resource is equivalent to poor capital investment, while congestion at busy hours could mean lost calls and lost revenues. It is therefore critical for wireless network designers to utilise these resources efficiently and effectively. In response to the above demand for next generation wireless and mobile communication systems, this book aims at providing a timely and concise reference of the current activities and findings in the relevant technical fields. The primary goal is to address the key technical issues pertaining to the integrated new systems and present novel technical contributions. The book contains 14 invited chapters from prominent researchers working in this area around the world.
Download or read book Emerging Personal Wireless Communications written by Olli Martikainen and published by Springer. This book was released on 2005-12-19 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of telecommunications has been largely based on mobile and data services in the past 10 years and the growth will continue. For instance, it is forecasted that after 2005 the mobile traffic turnover in Europe will exceed that of fixed telephone traffic and the penetration of Internet access through mobile will exceed that of fixed access. It is expected that the new value added services will be Internet-based and the IP traffic will outweigh the amount of traditional ISDN based telephone traffic. The transition from the existing telecommunications services to mobile and Internet based ones will change the service infrastructure as well as the customer and service management structures. In wireless communications there are several new standards being developed and implemented to improve the data transmission rate over radio channels, to combine both voice, packet data and multimedia services in the terminals and to improve the service quality and usability. Narrow band packet radio standards such as General Packet Radio Service (GPRS) and i-Mode are already operative and broadband IMT-2000 standards, also called as Third Generation (3G) Mobile, have been developed in Japan, Europe and US. At the same time Wireless LAN and Bluetooth technologies mature and provide short-range data access to terminal devices. The emerging new technologies create opportunities not only to incumbent teleoperators but also to new network operators, IT companies and new service and content providers.

Download or read book Mobile and Wireless Communications Networks written by Elizabeth M. Belding-Royer and published by Springer. This book was released on 2006-08-17 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad hoc NETworks (MANETs) has attracted great research interest in recent years. A Mobile Ad Hoc Network is a self-organizing multi-hop wireless network where all hosts (often called nodes) participate in the routing and data forwarding process. The dependence on nodes to relay data packets for others makes mobile ad hoc networks extremely susceptible to various malicious and selfish behaviors. This point is largely overlooked during the early stage of MANET research. Many works simply assume nodes are inherently cooperative and benign. However, experiences from the wired world manifest that the reverse is usually true; and many works [3] [10] [9] [8] [12] [19] have pointed out that the impact of malicious and selfish users must be carefully investigated. The goal of this research is to address the cooperation problem and related security issues in wireless ad hoc networks. As a rule of thumb, it is more desirable to include security mechanisms in the design phase rather than continually patching the system for security breaches. As pointed out in [2] [1], there can be both selfish and malicious nodes in a mobile ad hoc network. Selfish nodes are most concerned about their energy consumption and intentionally drop packets to save power. The purpose of malicious nodes, on the other hand, is to attack the network using various intrusive techniques. In general, nodes in an ad hoc network can exhibit Byzantine behaviors.
