Performance evaluation of ITLinQ and FlashLinQ for overlaid device-to-device communication

Abstract

We present a performance evaluation of ITLinQ/nand FlashLinQ, the two most popular schemes proposed to date/nto channelize D2D transmissions, i.e., to parse transmissions/ninto noninterfering sets to be allocated to separate channels./nRecognizing that it captures well the spatial characteristics of/nD2D networks, a stochastic geometry setting is utilized for this/nevaluation with the parameters of either scheme optimized in/norder to maximize the system spectral efficiency (bits/s/Hz per/nunit area). Although independently formulated and seemingly/nbased on different principles, both schemes are found to exercise/nsimilar mechanisms to avoid situations of excessive interference,/nyielding substantial improvements with respect to unchannelized/nnetworks.
