Book Synopsis Technology And Techniques Behind Wireless Communication by : Dr. S. V. Rama Rao
Download or read book Technology And Techniques Behind Wireless Communication written by Dr. S. V. Rama Rao and published by AG PUBLISHING HOUSE (AGPH Books). This book was released on 2023-01-04 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of wireless technology is not novel either. Many engineers, however, lack experience with the development of wireless technologies or the incorporation of wireless devices into the operation of industrial facilities. The theory and practise of wireless communications in an industrial setting lack in depth technical knowledge. Not everyone is convinced that wireless solutions can provide the promised reliability in the typically unfavourable conditions seen in most manufacturing settings. This textbook provides a holistic overview of wireless communication principles and explains the tangled web of ideas behind these innovations in a way that is accessible to students with a foundational understanding of probability and digital communication. The purpose of this book is to provide a cohesive presentation of current ideas in wireless communication and to contextualize those ideas within the larger framework of the wireless systems to which they have been applied. This work was designed for use in a first-year graduate level wireless communication course. Proficiency in signal and system theory, probability, and digital communication from an undergraduate or starting graduate level course is assumed.

Book excerpt: The current book provides a final report of activity performed by the COST 290 Action, ‘‘Traffic and QoS Management in Wireless Multimedia Networks,’’ which ran from March 10, 2004, until June 3, 2008. After an introduction to the COST framework and the Action’s survey time-frame and activities, the main part of the book addresses a number of technical issues, which are structured into several chapters. All those issues have been carefully investigated by the COST 290 community during the course of the project – the information presented in this book can be regarded as ultimate for each particular topic; every open research issue addressed in the book is described carefully, corresponding existing studies are analyzed and results achieved by the COST 290 community are presented and compared, and further research directions are defined and analyzed. Because the book covers a wide area of research addressing issues of modern wired and wireless networking at different layers, starting from the physical layer up to the application layer, it can be recommended to be used by researchers and students to obtain a comprehensive analysis on particular research topics including related areas, to obtain broad and ultimate referencing, and to be advised on current open issues. COST 290 is one of the Actions of the European COST Program. Founded in 1971, COST is an intergovernmental framework for European Cooperation in the field of Scientific and Technical Research, allowing the coordination of nationally funded research on a European level.

Book Synopsis Voice Quality Framework for VoIP Over WLANs by : Md. Atiur Rahman Siddique
Download or read book Voice Quality Framework for VoIP Over WLANs written by Md. Atiur Rahman Siddique and published by . This book was released on 2010 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voice over IP (VoIP) has quickly been adopted by commercial and private users dueto its low cost of service. To attain an even greater consumer acceptance by offeringthe convenience of mobility, we have to use a wireless carrier to deliver VoIP packetsat mobile phones. The low cost of service is the ultimate bargaining chip of VoIP andusing a high cost cellular network, like GSM or CDMA, for the last mile coverage compromises its appeal. The IEEE 802.11 WLANs, in this regard, offer a low cost wirelesscoverage which intrigued many researchers and device manufacturers to investigatethe voice performance in WLANs using theoretical analysis and simulation. Simulation based studies offer only restricted insight since the call capacity after changingany network aspect can not be determined easily and, therefore, analytical capacity models are more helpful to network designers and administrators. But a numberof over-simplified assumptions used in the existing voice capacity models make thesestudies impractical. Standard voice quality measures were ignored and unrealistic assumptions were used in modeling the IEEE 802.11 medium access mechanisms, whichmake the results unreliable.In this thesis, we model the voice capacity of the DCF and PCF based WLANswith a special attention to the voice quality to assist in network design and planning.We use the ITU-T E-model to determine the voice quality and formulate a qualityimpairment budget for medium and high quality calls. We develop two novel Markovmodels to estimate the delay and loss in the DCF and PCF based medium accessmechanisms. To model real world environment closely, we consider the impacts of imperfect channel and capture effect. Since most WLANs operate under the unsaturatedcondition for a considerable amount of time, we consider both saturated and unsaturated traffic conditions. In conjunction to network performance, we also incorporatethe characteristics of voice codecs and dejitter buffer. We identify that the delay andloss in the queue degrade voice quality significantly and utilize standard queuing analyses to determine its impact. Extensive simulation studies show a close match withour analytical results.In the current literature, no analytical model exists for the voice capacity of multichannel, multihop WLANs with multi-interface nodes. Especially, the formation ofcritical zones due to accumulated packet arrivals in multihop networks creating abottleneck was never considered. We model multi-interface WLAN nodes operating inmultichannel, multihop WLANs and determine the voice capacity of such networks.We also identify and analyze the benefit of utilizing multihop networks in order toexercise spatial reuse and improve voice capacity.Considering that DCF offers wider coverage and spatial reuse while PCF offerslower delay by the use of time synchronized medium access, we present a novel mediumaccess mechanism that combines the best features of the above two and yields performance benefits including VoIP call capacity increase through the introduction of"virtual access point" concept. The protocols for different network scenarios are explained and performance comparisons to the DCF and PCF based medium access areillustrated. The capacity models proposed in this thesis will be very useful in designing WLANs to maintain acceptable voice quality using off-the-shelf WLAN devicessupporting DCF and PCF while the incorporation of our proposed medium accessmechanism will improve the voice performance in future WLANs using virtual accesspoint enabled mobile devices.
