Software Defined Networking (SDN) has been deemed as a revolutionary technology promising for facilitation of network management. However, transitioning the network paradigm may cause operational, deployment and economical challenges that can be mitigated with seamless interoperability among SDN and existing IP devices. This research presents a Hybrid Routing Architecture for Software Defined Wireless Mesh Networks, leveraging SDN with WMNs in systematically incremental and operational manner. This paper aims to propose modifications in the architecture of SDN node that allows it to operate various network functions such as routing, load balancing, network monitoring and traffic measurement for a hybrid SDN and IP network. Simulations have been carried out using Mininet-WiFi to create a hybrid network environment with varying number of nodes. Results are taken on the basis of the average UDP throughput, and the comparison show that SDNHybridMesh performs better than the traditional OLSR routing protocol. © 2020, Springer Nature Switzerland AG.
