SPECTS_Summary
In this paper we compared methods for propagation effects at 60 GHz (rain) compensation, that use different protection mechanisms to prevent from traffic loss. First is adaptive link capacity in which links receiver threshold is improved at expense of link capacity, by reducing noise bandwidth combined with forward error correction. The second is network rerouting after link drop that was caused by rain attenuation, and the third is combination of previous two. As a network performance parameter we use network availability and link loads. Starting from 2D rain distribution moving across network graph and with shortest path based routing protocol simulator we evaluated network availability and link load as network performance parameters. Simulated results show that in a network with considerable redundancy (at least two links are connected to each router), rerouting is better protection mechanism.
