Impact of the overlapping area on the capacity of the network. The results are shown for a fixed SNR of 5 dB and for a varying distance d between the Relays. The curve Basic access denotes the capacity of the basic IEEE802.11s access, i.e., when blocked transmissions are not mitigated. The curves ZF and SJNR represent the capacity gain obtained from these schemes (Section 4). We can observe that reducing the distance between the two relay STAs degrades the capacity of the network. However, this negative impact can be mitigated through the ZF and SJNR techniques we propose. Moreover, the SJNR beamformer outperforms the ZF scheme by more than 10% and the basic IEEE802.11s access scheme by up to 85%.
