Executive Summary

This paper studies the problem of bulk data transfer between a pair of moving vehicles as they encounter, using IEEE 802.11p (Dedicated Short Range Communication, or DSRC) radios. Comparing to the well-studied problem of "Drive-Through Internet", enabling an efficient, reliable and fair data transfer between two fast-moving vehicles could be even more challenging because the effective link duration is halved, vehicle-to-vehicle channel is unpredictable and DSRC is a new technology. The authors design an Encounter Transfer Protocol (ETP) which is suitable for this vehicle encounter case.
