Through the above LP based routing which is actually an optimal routing scheme, we can obtain a bound on the throughput gain in FiWi networks compared with traditional WMNs.
Whereas in practical scenarios, such technique is unlikely for use.
Therefore, we propose a practical routing scheme in which traffic between wireless peers in FiWi may benefit more from the wireless-optical-wireless mode so as to achieve the network throughput gain.
