Wireless Link Scheduling Under a Graded SINR Interference Model
Source: Stony Brook University
In this paper, the authors revisit the wireless link scheduling problem under a graded version of the SINR interference model. Unlike the traditional thresholded version of the SINR model, the graded SINR model allows use of "Imperfect links", where communication is still possible, although with degraded performance (in terms of data rate or PRR). Throughput benefits when graded SINR model is used instead of thresholded SINR model to schedule transmissions have recently been shown in an experimental testbed. Here, they formally define the wireless link scheduling problem under the graded SINR model, where they impose an additional constraint on the minimum quality of the usable links, (expressed as an SNR threshold bQ).
