Abstract
Network virtualisation has been recently presented as a mean to overcome the saturation of the current Internet by sharing the same infrastructure by different network operators. This work considers virtualisation of the wireless medium, a way to share common network physical resources by different Virtual Operators based on a Time Division Multiple Access technique. We propose an Adaptive Weighted Round Robin scheduler as a means to optimize the assignment of time slots to each virtual operator and improve the performance of the system. End-to-end delay and packet loss are the metrics used in this paper to show the potential and limitations of wireless virtualisation as a way to increase the network usage. This research is presented as a simulation-based study developed over the widely used NS2 network simulator. Different scenarios and network topologies are considered in order to assess the benefits of using the proposed scheduler.
