摘要：Wireless Mesh network (WMN), serves as a key
to enable wireless communication technology for indoor,
enterprise and community networks besides the hard-wired
networks. Characteristics features of WMN promise to provide
a highly scalable wireless backbone. Despite this promise, the
current WMN architecture is inflexible to fulfill the recent
explosion of smart services and applications requirements.
Moreover, network management itself is a difficult task.
Software-Defined Networking (SDN) presents flexible network
architecture, it creates centralized network control, offers
simple and programmable forwarding devices totally
abstracted from network applications. However, to improve
reliability, scalability, and performance of SDN architectures,
a number of logically centralized but physically distributed
control plane design approaches have been proposed in order
to overcome the expected bottleneck in a physical centralized
approach. In this paper, firstly, we highlight the challenges of
current SDN distributed control plane. Secondly, we propose
Decentralized Software-Defined Wireless Mesh Network (DSDWMN)
architecture to address these issues in SDWMN. DSDWMN
is a framework that presents physical and logical
distributed SDWMN control plane. D-SDWMN adopts a
hierarchy distribution of controllers that can adapt to WMN
distributed nature. Distributed local controllers enhance
WMN’s scalability and reliability. Furthermore, they boost
main controller performance by decreasing control flow
overhead. That positively affects the WMN performance. The
initial results evaluation shows the quality of D-SDWMN
properties.
