Delay-Sensitive Sensitive Area Spectral Efficiency: A Performance Metric for DelayDelay Constrained Green Networks
Abstract: This paper introduces a new metric, referred to as delay delay-sensitive sensitive area spectral efficiency (DASE), to analyze the performance of delay delay-constrained constrained wireless networks. We study DASE in different point point-to-point, point, spectrum sharing, interference, and Poisson-po point process-based based dense network configurations and with different levels of channel state information (CSI) at the transmitters. Also, we determine the optimal rates/powers optimizing DASE. Finally, we use some recent results on finite block block-length codes to o analyze the effect of the codewords length on the network DASE. As demonstrated, DASE is a useful metric for analyzing delay-sensitive sensitive green networks. Moreover, adaptive power allocation and partial CSI feedback are powerful tools for performance improvement improve in green networks.
