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.
