Abstract

Millimeter-wave networks have the potential to supplement fiber in providing high-speed Internet access, as well as backhaul for emerging mobile 3G and 4G services. However, due to the high frequency of operation (70---90 GHz), such networks are highly susceptible to attenuation from rain. In this paper, we present several mechanisms to overcome the disruptive effects of rain storms on network connectivity and service reliability. A resilient mesh topology with cross-layering between the physical and network layer has the capability to self-optimise under the presence of unstable links. We present a novel domain-specific predictive routing algorithm P-WARP that uses real-time radar data to dynamically route traffic around link failures as well as a modified link-state algorithm XL-OSPF that uses cross-layering to achieve resilient routing. Simulations are conducted to evaluate the effectiveness of the proposed algorithms.
