An efficient traffic management framework for multi-channel wireless backbone networks

Abstract

This paper presents a traffic management framework for multi-channel wireless backbone network (WBN). To date, WBNs are not allowed to flexibly use multiple channels even if there are many vacant channels. Furthermore, the limited available channel(s) are not utilized effectively. Therefore, we propose a virtual AP enabling to handle the unlimited number of channels potentially, and then present a traffic control framework with OpenFlow, which freely controls traffic on multiple channels. Experimental results show that WBN linearly increases the network capacity according to the increase in the number of channels. That is, effective utilization of multi-channel can be achieved.
