This paper examines the energy needs of the world IT infrastructure. We show that small networks, such as intra-building and access networks, consume more energy than large networks. We also examine topologies and technologies that can improve the energy efficiency of the foregoing small networks.
Radio-over-Fiber (RoF) based network architectures would allow centralization of signal processing and signal conditioning functions and simple, cost-effective remote units at the cell site. RoF technology results in remote units with few components, however, certain aspects of the technology may inadvertently lead to high power consuming components. In this paper, we experimentally investigate the...
With the growing popularity of high-performance computing devices such as tablets and smart-phones, and the growing trends of cloud-based services, forecasts indicate that the majority of Internet traffic will originate from inside of the buildings. Thus indoor network infrastructure needs to provide both better capacity and better coverage. Meanwhile, energy efficiency of the network becomes an additional...
The global network energy consumption is increasing at an alarming rate due to proliferation of the Internet and its increasing bandwidth-intensive applications. In this paper, we propose an energy efficient Access/In-Building architecture that features energy efficient customer premises equipment (CPE) design in conjunction with an energy efficient access network protocol, and in-building optical/wireless...
