With regard to each interference, NRMSE of schemes except for EM is almost the same.
To ensure a fair comparison, the same prototype filter, which is the SRRC filter,c is used for these schemes except for CP-OFDM.
SimpleSearch and HybridCache obtain a lower number of documents than the other caching schemes except for a speed of 1 m/s.
We observe that the QoS-awareness is achieved by all the schemes, except for the maximum throughput scheme which is QoS-oblivious.
The negative saturation poses no problem to any of our error correction schemes except for a value of −100 but then the image is just a grayscale image.
The speed of the nodes do not meaningfully affect the traffic load of the tested caching schemes except for DPIP, which generates more traffic as the speed increases.
As we observe, the trends are the same as in the case of 1 bpcu rate, i.e. AGSSK and AGSSK-TOSD outperform all schemes except for EGT with selection of the best subset of antennas.
The number of timeouts obtained is lower than those achieved by the other caching schemes except for MobEye and COOP, which perform slightly better but at the expense of doubling or tripling the traffic load.
Looking at Figures 3(a) and 3(b), we conjecture that for hop-by-hop transmissions, we should use BCH up to the second vertical dashed line, that is, a distance of 62 km, because when the distance is below 62 km, all of the schemes except for RS can achieve not less than probability, while BCH consumes the least energy.
In Figure 16 where the pre-correlation bandwidth is chosen equal to 12 MHz, both BOC-AW(1,1,α(4)) and BOC-AW(1,1,α(6)) WFs present the worst performances while BOC-AW(1,1,α(2)) performs better than all the modulation schemes except for OBOC-AW(1,1,α(2)) and CBCS.
