Cross-Layer Resource Allocation in Wireless Communications: Techniques and Models from PHY and MAC Layer Interaction

Resource allocation in wireless networks is traditionally approached either through information theory or communications networks. To break down the barriers between these distinct approaches, this book (whose preparation is carried out under the auspices of the EC Network of Excellence in Wireless Communications NEWCOM++) bridges the physical and network layers by providing cross-layer resource allocation techniques, models and methodologies.

Cross-Layer Resource Allocation's unique approach allows optimisation of network resources and will enable engineers to improve signal quality, enhance network and spectrum utilization, increase throughput, and solve the problem of shadowing. Topics covered include different views of spectral efficiency, the role of spatial diversity, of delay in resource allocation, and possible extensions to OFDMA systems.

This will be an ideal reference on cross-layer resource allocation between the PHY and MAC layers for R&D and network design engineers and researchers in universities dealing with sensor networks and cognitive systems.

"This is a nice treatise on the cross-layer optimization of wireless systems. The authors offer a useful guide on a timely subject most relevant to future generation of wireless communications." - Lang Tong, Irwin and Joan Jacobs Professor in Engineering, School of Electrical and Computer Engineering, Cornell University, USA

"The authors have written a book that offers to researchers and practitioners a thorough and comprehensive overview, with a cross-layer perspective, of theory, models and methods related to resource allocation in multi-user wireless systems." - Professor Velio Tralli, University of Ferrara Communication Technologies Laboratory

* Gives a full description of the characteristics of the PHY layer that promote efficient resource allocation strategies
* Gives special emphasis on cross-layer design for spatial diversity schemes
* Provides a framework for interaction between the PHY and MAC layers, their parameters of performance and their relationship
* Presents resource allocation as a cross-layer design based on an optimization of MAC layer parameters with an accurate model of the PHY layer

在無線網路中，資源分配通常是透過資訊理論或通訊網路的方式來處理。為了打破這些不同方法之間的障礙，這本書（在歐洲委員會無線通訊卓越網路NEWCOM++的支持下編寫）通過提供跨層資源分配技術、模型和方法，將物理層和網路層連接起來。

《跨層資源分配》的獨特方法可以優化網路資源，使工程師能夠提高信號品質、增強網路和頻譜利用率、提高吞吐量，並解決陰影問題。涵蓋的主題包括對頻譜效率的不同觀點，空間多樣性在資源分配中的作用，延遲在資源分配中的角色，以及對OFDMA系統的可能擴展。

這將是一本理想的參考書，供研發和網路設計工程師以及從事感測器網路和認知系統研究的大學研究人員在PHY和MAC層之間進行跨層資源分配。

「這是一本關於無線系統跨層優化的好著作。作者提供了一個有用的指南，涵蓋了一個與未來無線通訊相關的及時主題。」- Lang Tong，康奈爾大學電機和計算機工程學院Irwin和Joan Jacobs教授

「作者撰寫了一本書，從跨層的角度全面而詳細地介紹了多用戶無線系統中與資源分配相關的理論、模型和方法。」- Velio Tralli教授，費拉拉大學通訊技術實驗室
