Enabling green communication in future generation of cooperative and cognitive wireless systems

无线通信市场的爆炸式增长和多媒体移动的设备的激增导致了对高数据速率和无处不在的覆盖的需求的增加。认知无线电（CR）和基于中继的协作技术已经被提出来改善各种无线通信系统的吞吐量和覆盖。这些技术中的许多技术显著地增加了系统复杂性和能量消耗。不断升级的能源成本和环境问题已经产生了对更节能的“绿色”无线通信的迫切需求。本研究的主要目标是为下一代无线通信系统中的协作和认知网络设计节能算法和协议。

Explosive growth in wireless communications market and proliferation of multimedia mobile devices has led to increase in demand for high data rates and ubiquitous coverage. Cognitive radio (CR) and relay based cooperative techniques have been proposed to improve the throughput and coverage of various wireless communication systems. Many of these techniques significantly increase the system complexity and energy consumption. Escalating energy costs and environmental concerns have already created an urgent need for more energy-efficient "green" wireless communications. The main goal of the proposed research is to design energy-efficient algorithms and protocols for cooperative and cognitive networks for future generation of wireless communication systems.
