In this paper, we design a new software-defined wireless network architecture to enable high performance in the next generation of ship area networks (ShAN). We first introduce the current problem of end-to-end transmission delay in ship area networks, and then claim that both network and routing layers protocol will require improvement to guarantee data transmission. Hence, we propose a new network architecture, which combines SOTDMA and SDWN advantages to reduce end-to-end transmission delay to achieve high performance in ship area networks. We sketch out the changes and extensions of an SDWN network controller and switches to enable high performance. The complete design of an SDWN architecture using SOTDMA is an exciting avenue for future ship area networks. Using our proposed network architecture, our evaluation results show that for one wireless AP station, we can obtain 3 Mbps throughput.
