Resources-constrained communication and networking through adaptation and cooperation

点击翻译按钮获取中文摘要

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.
