本书涉及了协作通信的物理层,链路层,网络层等,原书作者】: Fitzek, Frank H.P.; Katz, Marcos D. (Eds.) 【ISBN 】:978-1-4020-4710-7 【页数 】:696【开本 】 :32【出版社】 :Springer; 1 edition (November 22, 2006) 【出版日期】:2006.11pdfAbout this book Cooperation is known as an effective strategy in nature to achieve individual or common goals by forming cooperative groups. As the cross over between nature and engineering has always beenfruitful, Cooperation in Wireless Networks: Principles and Applicationsadvocates the use of cooperative strategies in the field of wirelesscommunications. Whether to cooperate or act autonomously, i.e., in a more selfishmanner, has to be decided by each wireless terminal individually.Following the rule "The real egoistic behavior is to cooperate", mutualaid among terminals will be applied if and only if it is beneficial forall group members. Cooperation in Wireless Networks: Principles and Applications coversthe underlying principles of cooperative techniques as well as severalapplications demonstrating the use of such techniques in practicalsystems. The work is written in a collaborative manner by severalauthors from Asia, America, and Europe. Twenty chapters introduce anddiscuss in detail the main cooperative strategies for the wholecommunication protocol stack from the application layer down to thephysical layer. Furthermore power saving strategies, security, hardwarerealization, and user scenarios for cooperative communication systemsare introduced and discussed. The book also summarizes the strength ofcooperation for upcoming generation of wireless communication systems,clearly motivating the use of cooperative techniques and pointing outthat cooperation will become one of the key technologies enabling 4Gand beyond. This book puts into one volume a comprehensive andtechnically rich view of the wireless communications scene from acooperation point of view.
