论文摘要

扩大互联网的影响力是当今广泛兴趣的话题。 Google和Facebook等人已经开始投资大量研究工作,以扩大边缘的互联网访问。与数据中心网络相对过度设计相比,最后一英里的网络受到高度限制,最终最终负责影响用户体验的性能问题。 事实证明,提供最后一英里连接性的最可行性和成本效益的方法是无线ISP(WISP),它依靠点对点无线回程基础架构使用便宜的商品无线硬件来提供连接性。但是,已知各个WISP网络链接的可靠性差,整个网络的成本限制很高。 在这些观察结果的推动下,我们提出了具有冗余(WISPR)的无线ISP,该ISP利用了商品无线硬件固有的成本绩效折衷方案,以朝着WISP网络中的更多廉价链接迈进,从而降低了成本。为了利用这一新的道路多样性,我们引入了一种新的一般协议,可提供提高的性能,可靠性或两者的组合。

Expanding the reach of the Internet is a topic of widespread interest today. Google and Facebook, among others, have begun investing substantial research efforts toward expanding Internet access at the edge. Compared to data center networks, which are relatively over-engineered, last-mile networks are highly constrained and end up being ultimately responsible for the performance issues that impact the user experience. The most viable and cost-effective approach for providing last-mile connectivity has proved to be Wireless ISPs (WISPs), which rely on point-to-point wireless backhaul infrastructure to provide connectivity using cheap commodity wireless hardware. However, individual WISP network links are known to have poor reliability and the networks as a whole are highly cost constrained. Motivated by these observations, we propose Wireless ISPs with Redundancy (WISPR), which leverages the cost-performance tradeoff inherent in commodity wireless hardware to move toward a greater number of inexpensive links in WISP networks thereby lowering costs. To take advantage of this new path diversity, we introduce a new, general protocol that provides increased performance, reliability, or a combination of the two.
