Abstract: Future wireless communication paradigms that will form the basis of 5G and beyond architectures will rely on the availability of network infrastructure as a service. In this approach, the same radio and compute resources are partitioned to serve many users, each of which may prioritize different performance metrics. Thus, with the diversity of wireless services and applications, the current ”one size fits all” network architecture is no longer an option. Indeed, virtualization incorporates flexibility into the network architecture design to help meet the diverse application/user needs.
In this thesis we consider a shared compute resource that must support a number of wireless configuration options. We study the effects of CPU allocation alongside baseband (PHY Layer) configurations such as transmitter gain and Modulation and Coding Schemes (MCS), related to various performance metrics of containerized wireless communications systems. We analyze these results and quantify the trends to gain a better understanding of these multiple, interconnected effects. Finally we propose a controller to provide a user with required QoS from pre-defined Service Set identifiers (SSIDs) given the limited availability of CPU resources. We implement this controller system using open-source baseband software and USRP N310 platforms provided in the COSMOS testbed
