VI. CONCLUSION
This paper presents a new approach to carry peer-topeer communications in the integrated optical wireless access networks, so called FiWi networks.
By sending peer-to-peer communication traffic from one wireless client to its closest ONU through wireless subnetwork, which is then sent to the ONU close to the peer wireless client through PON subnetwork and then delivered to the peer wireless client through wireless subnetwork again, the interference in wireless subnetwork can be sustained, thus, network throughput can be improved.
Extensive simulations have been carried to study the network throughput gain introduced by FiWi network and our simulation results show that when peer-to-peer communication traffic is heavy, the network throughput gain in the FiWi network is significant compared with the traditional WMN.
The simulation results also show that the number of ONUs and ONU placement play important roles on the network throughput gain in FiWi networks.
