Energy efficient wireless infrastructure

该项目将解决与节能和能源可持续无线网络基础设施的设计和运营有关的关键问题。我们的长期目标是以经济高效的方式部署无线基础设施，这将是未来各种应用所需要的。这包括网状无线局域网基础设施，以及用于传感器部署和车载路边网络等各种应用的基础设施。 随着互联网变得越来越普遍，无线连接在更加多样化和广阔的区域中被需要，在这些区域中有线电力连接不可用或过于昂贵。此外，无线基础设施正变得越来越便携，并且将仅由可充电电池源操作。实现这些类型的基础设施的关键是开发节能协议、高效的能源资源供应方法和节点放置技术。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实现这些目标。这项工作将包括：i）开发用于实际网络部署的能量资源供应技术，ii）评估使用现实电池效应的功耗益处，iii）调查使用机会性车辆访问的能量效率改进的潜力，iv）设计能量高效的车辆路边基础设施，以及，v）能量高效的移动的热点基础设施的协议设计。这项工作将解决一些关键的障碍，使具有成本效益的无线网络基础设施。

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.
