Next generation access network is looking for high reliability and flexibility, which Hybrid Wireless Optical Broadband Access Network (WOBAN) can offer, as a promising new network architecture. WOBAN is expected to combine the best of optical and wireless networks, to provide a robust, flexible and cost-effective hybrid solution. Another trend in future networking is to use Software Defined Network (SDN), as a new approach in management and implementation of enterprise network. Instead of a building a messy, scattered network with thousands of devices, service providers can look forward to a centralized, high programmable and scalable network setup regardless of vendors. So far a lot of researches have been focusing on each individual topic, but only a few targeted to combine these two approaches onto a single proposal. Hence, in this project, we propose a Hybrid WOBAN design and use SDN platform to test the network performance as well as its programmable controller. A simulation model running on Mininet is demonstrated and evaluated using different controllers and topologies written on Python programming language. We used the bandwidth efficiency and delay to evaluate the performance. After conducting various test scenarios, the results have shown that the choices of controller as well as the link parameters have a great effect on the performance of the network.
