Given the total traffic demand, if all traffic goes to the Internet, the network throughput gain of the FiWi network is marginal compared with the traditional WMN since the interference in the wireless subnetwork is the bottleneck.
This is verified by Fig. 3 where we set the total traffic demand in the network to be 200Mbps.
When 100% of the traffic goes to the Internet, the throughput of FiWi network is the same as that of traditional WMN.
However, with the increase traffic demand for peer-to-peer communications, the interference in the wireless network increases and the network throughput in traditional WMNs decreases dramatically.
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
