Reliable package delivery protocol for geocast - protocol in a separate vehicle - - - ad hoc network

摘要

It is a method for supplying data messages in an ad hoc network - - is created between vehicles. The ad - hoc - network between vehicles uses a longer - routing - protocol for storing, transferring and distributing a data message to different vehicles, which move along the road. The method comprises determining a first cluster, which consists of a group of vehicles in the vicinity of one another, which, in a first direction to move along a road. It is a determination is carried out, which vehicles within the first cluster rear vehicles are, in order to messages on the basis of the vehicle position within the first cluster to send again. By means of one of the vehicles in the first cluster, an event in a travel path of the first cluster detected. The event is transferred to other vehicles in the cluster reported. It is at least one vehicle is in a second cluster is detected, which is located in an opposite direction to the first cluster moves. The data message is determined by the specific rear vehicles is transmitted to the second cluster round.
