Title Software Defined Networks (SDNs) and their Potential Utilization in Wireless Mesh Networks (WMNs)

This talk will explore the potential of Software Defined Networks, which have received significant attention by the research community and network operators/vendors for the past few years, mainly because of programmable capability that it offers. SDN approach shifts the traditional distributed routing toward a centralized routing mechanism. Taking the control plane off from the routers by making them simple data forwarders, more control to network operators can be provided, which can implement different policies according to their requirement. The discussion will also cover the role and impact of SDN approach, which allows QoS policies to be implemented in a better way in the network, and enables new technologies to be implemented in the network without requiring to change the hardware. Despite having many SDN solutions for wired networks, little attention has been given towards application of SDN techniques in wireless networks and more specifically towards wireless mesh networks (WMN). The talk will conclude by briefly touching upon the potential of SDN techniques to be effectively used in WMNs, by making mesh routers as simple data forwarders which can be controlled/configured through a controller at distance. This can help reduce the significant infrastructure cost associated with WMN. Moreover, this will also make it possible to quickly develop and implement new techniques related to WMN.
