Software-Defined Networking (SDN) firstly has emerged in wired networks, and then it has extended to wireless networks. Software-Defined Wireless Networking (SDWN) has a great potential to increase efficiency, ease the complexity of control and management, and accelerate technology innovation rate of wireless networks. To improve the reliability and performance of SDN’s architectures, a logically centralized but physically distributed controller design has proposed. However, there are two key problems have appeared. First, the control plane network managing task. Second, the distributed controllers’ deployment is manual and static. To address these two problems in Software Defined Wireless Mesh Networking (SDWMN), this paper presents a novel architecture called Dynamic Distributed SDWMN (DDSDWMN) to bootstrapping SDN-based WMN architecture and dynamic deploying the distributed controllers. The controller needs to have updated reports of the network status’ changes. The global controller aggregates entire topology discovery and monitor QoS properties of extended WMN nodes using LLDP protocol, which unable in multi-hop ordinary architectures. DD-SDWMN has implemented in Mininet-wifi emulator on top of POX controller and Advanced Message Queuing Protocol (AMQP). The results present the DD-SDWMN control plane consistency and two functional applications: topology discovery and QoS monitoring. The current results lead to future studies on QoS routing in WMN.
