Energy efficient wireless infrastructure

该项目将解决与高能效和能源可持续的无线网络基础设施的设计和运营有关的关键问题。我们的长期目标是实现具有成本效益的无线基础设施部署，这将在未来的各种应用中使用。这包括网状网络无线局域网基础设施，以及将用于传感器部署和车载路边网络等不同应用的基础设施。 随着互联网变得更加无处不在，人们需要在更加多样化和广阔的地区进行无线连接，在这些地区，有线电源连接不可用或昂贵得令人望而却步。此外，无线基础设施正变得越来越便携，并将完全由可充电电池供电。实现这些类型的基础设施的关键是开发节能协议、高效的能源供应方法和节点布置技术。这是一个相对较新的领域，因为传统的基础设施通常是在假设固定电网连接的情况下设计的。 拟议的活动以一些新颖的方式处理这些目标。这项工作将包括：i)为实际网络部署开发能源资源供应技术；ii)评估使用真实电池效应带来的电力消耗好处；iii)调查使用机会车辆接入提高能源效率的潜力；iv)设计高能效的车辆路边基础设施；以及v)高能效移动热点基础设施的协议设计。这项工作将解决实现具有成本效益的无线网络基础设施的一些关键障碍。

This project will address key issues relating to the design and operation of energy efficient and energy sustainable wireless network infrastructure. Our long-term goal is to enable the cost-effective deployment of wireless infrastructure which will be needed in a variety of future applications. This includes mesh-networked wireless LAN infrastructure, and infrastructure to be used in such diverse applications as sensor deployments and vehicular road-side networks. As the Internet becomes more ubiquitous, wireless connectivity is needed over much more diverse and expansive areas, where wired power connections are unavailable or prohibitively expensive. In addition, wireless infrastructure is becoming increasingly portable, and will be operated solely from rechargeable battery sources. The key to enabling these types of infrastructure is the development of energy efficient protocols, efficient energy resource provisioning methods and node placement techniques. This area is a relatively new one, in that classical infrastructure has been typically designed assuming fixed power grid connections. The proposed activities address these objectives in a number of novel ways. The work will include: i) the development of energy resource provisioning techniques for practical network deployments, ii) an assessment of the power consumption benefits from using realistic battery effects, iii) an investigation of the potential for energy efficiency improvement using opportunistic vehicular access, iv) the design of energy efficient vehicular road-side infrastructure, and, v) protocol design for energy efficient mobile hot-spot infrastructure. This work will address some of the key barriers to the enabling of cost-effective wireless network infrastructure.
