Wireless Sensor Networks: A Cognitive Perspective (Hardcover)

With classical techniques for data transmission soon reaching their limitations, cognitive approaches may offer a solution to user requirements for better coverage, connectivity, security, and energy efficiency at lower cost. Wireless Sensor Networks: A Cognitive Perspective presents a unified view of the state of the art of cognitive approaches in telecommunications. A benchmark in the field, it brings together research that has previously been scattered throughout conference and journal papers.

Cutting-Edge Topics in Cognitive Communications

After a review of the cognitive concept and approaches, the book outlines a generic architecture for cognition in wireless sensor networks. It then targets specific issues that need to be addressed through cognition, from cognitive radio and spectrum access to routing protocols. The book also explores how to use weighted cognitive maps to improve network lifetime through optimizing routing, medium access, and power control while fulfilling end-to-end goals. The final chapter discusses the implementation of hardware for GPS/INS-enabled wireless sensor networks. This addresses an important need for real-time node position information in many wireless sensor network applications and communication protocols.

Real-World Applications of Wireless Sensor Networks using the Cognitive Concept

Written in a tutorial style, the book supplies an in-depth survey of each topic, accompanied by detailed descriptions of the algorithms and protocols. It also provides a step-by-step analysis of the various communications systems through extensive computer simulations and illustrations. Examples cover environmental monitoring, vehicular communications, tracking, and more. A comprehensive overview of cognitive communications in wireless sensor networks, this work lays the foundations for readers to participate in a new era of research in this emerging field.

傳統的資料傳輸技術很快就會達到其極限，認知方法可能提供一個解決方案，以滿足使用者對更好的覆蓋範圍、連接性、安全性和能源效率的需求，並以更低的成本實現。《無線感測網絡：認知視角》提供了電信領域認知方法的最新狀態的統一觀點。作為該領域的基準，它匯集了以前分散在會議和期刊論文中的研究成果。

在對認知概念和方法進行回顧後，本書概述了無線感測網絡中認知的通用架構。然後，它針對需要通過認知來解決的特定問題，從認知無線電和頻譜訪問到路由協議進行了討論。本書還探討了如何使用加權認知地圖來通過優化路由、媒介訪問和功率控制來改善網絡生命週期，同時實現端到端的目標。最後一章討論了在GPS/INS啟用的無線感測網絡中實現硬件的問題。這解決了許多無線感測網絡應用和通信協議中實時節點位置信息的重要需求。

本書以教程風格撰寫，提供了每個主題的深入調查，並詳細描述了算法和協議。它還通過廣泛的計算機模擬和插圖，逐步分析了各種通信系統。例子涵蓋了環境監測、車輛通信、追踪等領域。作為無線感測網絡中認知通信的全面概述，本書為讀者參與這一新興領域的研究奠定了基礎。
