Virtual MeshTest - Improving Wireless Network Testbed Using Virtualization and Migration Algorithm
There are several laboratory-based mobile wireless testbeds such as the MeshTest and the CMU wireless emulator. These testbeds provide powerful computing network platforms for users who want to perform controlled, repeatable, mobile experiments in the lab. However, such systems can only use 10-15 nodes in an experiment. The Virtual Mesh Testbed (VMT) adopts virtualization technology and performs experiments on more nodes than previous or existing wireless testbeds. Furthermore, a new live migration algorithm for managing nodes is implemented in order to maximize the utilization of the testbed. Using this algorithm, the testbed can allocate virtual nodes to physical nodes as far as the number of RF-switches is allowed.
