Abstract

In today’s networks, two new concepts have emerged aiming at cost reduction and control network congestion, namely Network Functions Virtualization (NFV) and Software Defined Networking (SDN). NFV proposes to run the network functions as software instances on datacenters (DC), while SDN presents a new network architecture where the control plane is shifted to a centralized controller. Wireless Software Defined Networking (WSDN) is considered based on the wireless environments, such as propagation delay and external interference. It is critical to keep the network stable at the ideal stable state during congestion control. However, stability control is insufficient to achieve these aims in the presence of propagation delay and external interference.
