Virtualization in Wireless Networks

Typical Grid Utilization

Virtualization Support concurrent experiments Support both short-term and long-term service experiments Allow fine-grained control over radio parameters and topology Used a combination of methods –Virtual MAC (VMAC), Space division, Frequency division, Time division

PlanetLab Nodes Running VINI LOSAHSTNSTTL OpenVPN Ethernet Tunnel Access Point Access Point Video Server Mobile Client

PlanetLab Nodes Running VINI LOSAHSTNSTTL OpenVPN Ethernet Tunnel Access Point Access Point Video Server Mobile Client / / /30 ( /30)

Problems & Challenges When using IP tunneling (rather than Ethernet tunneling), OpenVPN must know the IP ranges that it is responsible for routing in advance. This makes it impossible to use IP tunneling for mobile nodes or topologies where IP ranges change. When using Ethernet tunneling, ARP proxying must be enabled on the VINI/ORBIT gateways. There is no perfect method of detecting client timeouts to trigger disconnection of a client and the retraction of it’s associated route. Assigning each mobile node a /30 wastes IP addresses. Each mobile client will need a unique: Network address, Broad cast address, Gateway address and Host address. Only 64 mobile IP clients can be assigned per Class C (256 IP addresses)
