Virtual Access Points for Stream Based Traffic Dissemination

In this paper we consider the problem of dissemination of stream based traffic using access points as roadside equipment. We consider how areas outside direct coverage can still be reached by means of other vehicles acting as virtual access points (VAPs). The developed technique, allows transparently extending the reach of roadside access points to uncovered road areas. VAPs are designed to avoid interference, operating in regions bounded outside any AP. The simulations show the presented mechanism to exhibit gain, in terms of received messages, of 30% and perhaps more significantly, that streaming data delivery becomes feasible.
