Abstract:
This paper proposes an efficient multi-channel utilization method that reduces packet loss on software defined multi-channel wireless mesh network (SD-WMN). In SD-WMN, multiple channels can be used in parallel along with a route. To utilize multiple channels efficiently, we proposed a channel utilization method that balances the channel load by exploiting the flow-based control of OpenFlow. However, packet loss often occurs under this proposed method. Specifically, this method balances the network load, thereby decreasing the available capacity of each channel. Along to this, an acceptable flow also becomes smaller. A channel may run out of capacity when a large flow arrives, even if the total available capacity provided by SD-WMN is sufficient for that flow. Thus, in this paper, we propose a new method that is optimized to increase the available capacity on some of all channels by intentionally making the channel utilization imbalanced. When a new flow arrives, the flow is transmitted on the channel, thereby minimizing the possibility of packet loss. We then conduct some experiments in various scenarios and show that the method can extremely decrease the packet loss at the time when a flow arrives.
