Existing Infrastructure DOME consists of DieselNet: 40 equipped public transit buses Amherst Mesh: 26+ APs Open third-party APs A large potential user base Not part of GENI: ○ TurtleNet ○ Solar-powered Throwbox relays ○ Bus cameras
DieselNet 4 Each public transit bus is equipped with a small computer (1GB, 60GB), 802.11b AP, 802.11g PCI, XTend 900Mhz radio, 3G modem, and GPS.

A Well-tested Testbed Operational since May 2004 Working relationships with Transit and Town 14 papers published based on testbed experiments e.g., Mobicom, Mobisys, Mobihoc, Sigcomm, Infocom 6 traces of testbed operation available ○ http://traces.cs.umass.edu Live web tracking of bus locations Platform…
GENI Interactions Major Framework Goals Disconnected operation / weakly connected env. Pre-staging of virtual machines/experiments Primary extra-cluster project interactions Albrecht’s GUSH Gruteser’s Orbit Vehicles Opt-In WG GaTech DARPA/NETS partner; MSR VanLan 6–12 months out Virtual machine staging; Atheros PCI control Interface to ORCA
Summary Cluster D ORCA framework team Vehicular network and public mesh Virtual machine operation on each bus Connections to other buses, mesh nodes, public/open APs; 3G backbone Connections to several other projects Virtualization demo in month 6.
