Evaluation of UML Based Wireless Network Virtualization

Wireless virtualization aims to support concurrent experiments on shared wireless network resources. This research is based on efforts to enhance the control structure of the wireless test bed 'ORBIT' through different forms of virtualization. The focus of this paper is virtualization in frequency or Frequency Division Multiplexing (FDM), and more specifically using multiple wireless interfaces per node and splitting the wireless medium by assigning a different channel frequency to each interface. A wireless node is then virtualized through User Mode Linux (UML), with each sliver or experiment using a different interface.
