Future ubiquitous green mesh relay network design based on distributed beamforming

商业上可获得的无线基础设施，例如，移动电话网络，在我们的日常生活中扮演着重要的角色。然而，这些基础设施在跟上可靠和快速无线通信的不断增长的需求方面似乎效率低下。例如，在传统技术下，稀缺的频谱无法支持实时多媒体通信对千兆或兆兆比特/秒吞吐量的需求。作为另一示例，蜂窝网络中的功耗在2007年估计为约60 TWh并且保持增长。这些情况表明，现有技术过于昂贵，效率低下，无法以负担得起的价格可持续地运作。因此，需要更高带宽效率、更高功率效率和更动态的基础设施，以确保随时随地与任何人进行无缝通信。为了设计下一代泛在网络，

The commercially available wireless infrastructures, e.g., cellular phone network, have played a remarkable role in our everyday lives. However, these infrastructures have appeared to be inefficient in keeping up with the ever increasing demand of reliable and fast wireless communication. For instance, under traditional technologies, the scarce frequency spectrum cannot support the demands for Giga- or Tera-bps throughput for live multi-media communications. As another example, the power consumption in cellular networks was estimated to be about 60 TWh in 2007 and keeps growing. These indicate that the available technologies are too expensive and inefficient to sustainably operate at an affordable price. Therefore, more bandwidth efficient, power-efficient, and dynamic infrastructures are required to ensure the seamless communications of anything at anytime to anyone. To design the next generation of Ubiquitous Network, fundamental innovative ideas for the
