Whereas due to the wireless-optical-wireless communication mode, the network throughput in FiWi network does not decrease significantly, which strengthens our motivation to study the network throughput gain in FiWi network subject to peer-to-peer communications.
This is also supported by Fig. 4 where the practical routing scheme is applied with the same parameters.
In Fig. 4, although the throughput of FiWi networks is occasionally smaller than that of traditional WMNs and the network throughputs in both FiWi networks and traditional WMNs are relatively smaller than the corresponding value in Fig. 3 due to the practical routing scheme, the whole trend of network throughput gain in FiWi networks shown in Fig. 4 is consistent with that in Fig. 3.
