A two-layer window-based fairness control scheme for rings with spatial reuse

摘要

Quota-based fairness control on a ring with spatial reuse inherently brings about bandwidth waste due to a nature of fairness control. This paper suggests a cycle window and proposes a fairness control scheme based on a two-layer window composed of cycle and packet windows, under which the otherwise wasted bandwidth can be reused to carry, in advance, packets allocated to future fairness cycles.
