Cognitive Wireless Networks: Concepts, Methodologies and VisionsInspiring the Age of Enlightenment of Wireless Communications (Hardcover)

In the Age of Enlightenment the German philosopher Immanuel Kant encouraged people to use their own mind as the basis for reasoning instead of following dogmatic religious rules - Sapere aude! (dare to know!) - Today wireless communication networks are increasingly becoming aware of the conditions of its their component parts and surrounding environment. Cognition, a continuous process involving sensing, reasoning, understanding and reacting, can be applied to wireless networks in order to adapt the system to the highly dynamic wireless ecosystem. The ultimate goals are to enhance the efficiency in the use of radio resources as well as to improve both link and network performance. This book presents a detailed overview of a rapidly emerging topic in modern communications: cognitive wireless networks. The key aspects of cognitive and cooperative principles in wireless networks are discussed in this book. Furthermore, Cognitive Wireless Networks advocates the concept of breaking up the cellular communication architecture by introducing cooperative strategies among wireless devices. Cognitive wireless networking is the key to success in handling the upcoming dynamic network configurations and exploiting this cross-over to the fullest extent.

As wireless networks become pervasive, highly populated and increasingly complex, the essential preconditions for exploiting rich interactions among mobile devices are better fulfilled. Today, these trends are giving rise to new communications paradigms making use of cooperation and cognition as the main underlying principles. Cognition, together with its complementary principle cooperation, confer to the wireless networks some degree of consciousness or understanding about their own existence, such as internal structure, capabilities, relationships to the outside world, limitations, current use of radio resources and many more. Current wireless networks are aware of their surrounding environment to a very limited extent, but in future wireless networks this capability will be highly developed, as a consequence of exploiting jointly cooperative and cognitive principles. Especially for cooperative wireless networks, where the communication scenario is highly dynamic, the mobile devices need to adapt their capabilities in a flexible manner, taking advantage of cognitive principles.

在啟蒙時代，德國哲學家康德鼓勵人們以自己的思考為基礎，而不是遵循教條性的宗教規則 - Sapere aude！（敢於知道！） - 如今，無線通信網絡越來越意識到其組成部分和周圍環境的條件。認知是一個連續的過程，涉及感知、推理、理解和反應，可以應用於無線網絡，以使系統適應高度動態的無線生態系統。最終目標是提高無線資源的使用效率，以及改善鏈路和網絡性能。本書詳細介紹了一個快速崛起的現代通信主題：認知無線網絡。本書討論了無線網絡中認知和合作原則的關鍵方面。此外，《認知無線網絡》提倡通過在無線設備之間引入合作策略來打破蜂窩通信架構的概念。認知無線網絡是成功應對即將到來的動態網絡配置並充分利用這種交叉的關鍵。

隨著無線網絡變得普及、人口眾多且越來越複雜，利用移動設備之間的豐富互動的基本條件得到了更好的滿足。如今，這些趨勢正在催生利用合作和認知作為主要基本原則的新通信範式。認知與其互補原則合作，賦予無線網絡一定程度的意識或對其自身存在的理解，例如內部結構、能力、與外部世界的關係、限制、目前對無線資源的使用等等。目前的無線網絡對其周圍環境的認識非常有限，但在未來的無線網絡中，由於共同利用合作和認知原則，這種能力將得到高度發展。特別是對於通信場景高度動態的合作無線網絡，移動設備需要以靈活的方式適應其能力，充分利用認知原則的優勢。
