We have constructed a DTN testbed composed of 30-40 buses operated by the UMass Amherst branch of the Pioneer Valley Transport Authority (PVTA) that we have fitted with a custom package of off-the-shelf hardware. This testbed is called UMassDieselNet. The transit buses service an area sparsely covering approximately 150 square miles. The route each bus is placed on each day is chosen by the garage dispatcher and can change during the day. Buses can leave the network at any time. We did not try to automatically determine the routes of buses, though this is possible with some significant effort. We decided against this approach after finding GPS data often inconsistent or containing gaps where line-of-sight to satellites was lost.
- network configuration
-
The testbed began operating in May 2004 with five buses. Each bus carries a HaCom Open Brick computer (P6-compatible 577Mhz CPU, 256MB RAM). An 802.11b Access Point (AP) is attached to each brick to provide DHCP access to passengers and passersby. A second USB-based 802.11b interface constantly scans the surrounding area for DHCP offers and other buses. Each bus also has a GPS device attached to the brick. Each brick runs Linux on a 40GB notebook hard drive.
