Software-defined wireless mesh networks: architecture and traffic orchestration

What is it about?

In this article, we study applying SDN concept to a wireless mesh network (WMN). We first propose a novel architecture of SD-WMNs, and identify several critical challenges. Since wireless spectrum is a scarce resource that is shared by both data and control traffic in SD-WMNs, we propose three spectrum allocation and scheduling algorithms that orchestrate both control and data traffic. Finally, performance is evaluated via extensive simulations.

Why is it important?

Software-defined Networking (SDN) has been envisioned as the next generation network paradigm by decoupling control plane and data plane, such that network management can be conducted in a centralized controller. We first propose a novel architecture of SD-WMNs, and identify several critical challenges.
