Resources-constrained communication and networking through adaptation and cooperation

尽管人们希望扩大无线通信的巨大进步所带来的好处，但当今无线技术及其应用的发展面临着资源限制的日益严峻的现实挑战。这些限制主要涉及频谱和能量的可用性，这将成为未来无线技术发展的核心问题。这就需要将重点从无线设计原则转移到资源认知范式。它将影响无线系统的信号处理、通信和网络的设计方法。围绕资源利用效率这一核心主题，无线网络和系统运行面临着控制高效、链路自适应、节点协同的新挑战。

Despite the desire to expand the benefits of the tremendous advance in wireless communications, the growth of today wireless technologies and their applications faces an increasingly challenging reality of resource limitations. The limitations mainly concern spectrum and energy availabilities, which are becoming the core issues of future wireless technology evolution. These necessitate a shift of focus on wireless design principles to the resource cognitive paradigm. It will impact the design methodologies of signal processing, communication, and networking for wireless systems. Surrounding the central theme of resource utilization efficiency, new challenges are arising for wireless network and system operation to be control efficient, link adaptive, and nodes collaborative.
