ABSTRACT: Vehicle probe information delivery systems
can be broadly divided into the center type and center-less type. Since
conventional center-type information delivery systems generate a large load on
the communications infrastructure and data center, research efforts have come
to be focused on the centerless type. However, existing vehicle probe
information delivery systems suffer from various problems including a limited
service area, low delivery efficiency, and lack of immediacy in delivery. Our
objective in this study is efficient delivery of vehicle probe information as
needed. We propose a delivery scheme that uses vehicle-to-vehicle
communication, infrastructure-to-vehicle communication, and mobile
communication as well as Geo cast. This combined use of multiple communication
methods achieves efficient information delivery by changing the communication
method to fit the current situation. The results of an evaluation by simulation
showed that the proposed scheme could deliver information efficiently in a
variety of environments.
