The Wireless Control Plane: An Overview and Directions for Future Research

2018 | Keywords Software-defined networks, Wireless control plane, Wireless SDN controller, Deep Reinforcement Learning,
The Wireless Control Plane: An Overview and Directions for Future Research
Software-defined networking (SDN), which has been successfully deployed in the management of complex data centers, has recently been incorporated into a myriad of 5G networks to intelligently manage a wide range of heterogeneous wireless devices, software systems, and wireless access technologies. Thus, the SDN control plane needs to communicate wirelessly with the wireless data plane either directly or indirectly. The ... Read more

On Stochastic Controller Placement in Software-defined Wireless Networks

2017 | Keywords SDN controller placement, Stochastic optimization,
On Stochastic Controller Placement in Software-defined Wireless Networks
Software-defined networking (SDN) abstracts and centralizes the network control functions in a software entity that runs on a server, known as SDN controller. The controller needs to respond to its controlled elements in a strictly timely manner, and the controller placement has a prominent effect on its response time. Originally, all SDN architectures assumed a physical wired connection between the ... Read more

Robust Controller Placement and Assignment in Software-defined Cellular Networks

Robust Controller Placement and Assignment in Software-defined Cellular Networks
Software-defined cellular networks (SDCN) have been recently introduced to enable flexible cellular network design that facilitates fulfilling 5G design requirements. Placement of controllers within the SDCN plays a crucial role in optimizing its performance. In this paper, we study the controller placement problem in SDCN, considering the uncertainty in cellular user locations. Specifically, our contributions are as follows. First, we ... Read more

An Efficient Back-off Mechanism for Simulation Study of VoWLAN Capacity Improvement using OPNET

2014 | Keywords Backoff Time, DCF Access Mecha, AMR Voice Codec, Voip, WLAN Ca, DCF Access mechanism, OPNET, Voip, WLAN, WLAN Capacity,
An Efficient Back-off Mechanism for Simulation Study of VoWLAN Capacity Improvement using OPNET
Integration of delivering VoIP services over WLAN access networks (VoWLAN) increased the demand to support multiple of active simultaneous calls. Thus improving VoWLAN capacity has been addressed. The researchers are continuously contributing in improving VoWLAN capacity, (i.e. increasing the number of VoIP simultaneous calls), for various WLAN architectures. Although a lot of modifications have been developed for IEEE 802.11 standards ... Read more
