Abstract
In a software-defined wireless mesh network, a centralized manner of managing and monitoring of the network occurs. The software-defined network (SDN) is the future of the upcoming generation network paradigm by separating control plane and data plane such that network management and optimization can be conducted in a centralized manner using global network information. In this paper, we proposed a novel architecture of software-defined wireless mesh networks to identify the issues of traffic balancing introduced due to node mobility. In order to reduce the overall response time of the SDN controller in the dynamic network topology, the new model predicts the probability of the link failure in the topology. Once the link failure is predicted, alternate selection of various routes proposed through the effective stability of traffic in the network is achieved and thereby overhead of the control plane is minimized. Utilizing ns-3 to efficiently address the above problem, we can enhance the network throughput and packet delivery fraction and minimize the delay in the network. Finally, performance is evaluated via extensive simulations.
