Emulating software-defined wireless network: Bicasting scenario

Abstract

Demands for higher data rate have always been increasing. The most prominent cause for this fact is the new always-connected lifestyle together with the emerging massive connected objects (i.e. IoT) and new bandwidth-hungry services. Depending on the technological aspects of the services and the underlying infrastructure, such requirement might need different strategies. In this work, we investigate strategies to increase data rate in wireless LAN by bundling available resources in different networks to be used by applications. We spesifically focus on the so-called bicasting mechanism in some scenarios which are run inside Mininet-Wifi, an SDN-based Wi-Fi network emulator. Several parameters indicating rate performance have been evaluated and presented. Though the main purpose of the bicasting has been achieved, our early result shows that a fine-tuned strategy might be necessary to further improve performance.
