    摘要： A vehicle network transmission method and a vehicle network transmission system are provided. The vehicle network transmission method comprises the following steps. A first transmission device transmits a data signal to a second transmission device. It is determined whether the second transmission device is located in a target area. If the second transmission device is located in the target area, then a geographic location of the first transmission device is retrieved and a transmission region of the first transmission device is calculated. It is determined whether all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region. If all of the third transmission devices adjacent to the second transmission device in the target area are located in the transmission region, then the second transmission device does not continue forwarding the data signal.

    摘要： A method for determining the position of a mobile node applied to a roadside unit (RSU) is provided. The RSU and a plurality of mobile nodes form a communication network of a road. The method includes the steps of: obtaining, by , via at least one sensor, first road information, wherein the first road information provides absolute position distribution information associated with the mobile nodes; receiving, by a communication device, second road information from a first mobile node of the mobile nodes, wherein the second road information provides relative position distribution information associated with the first mobile node and second mobile nodes adjacent to the first mobile node; and determining, by a comparison device, the position of the first mobile node on the road according to the first road information and the second road information.

    摘要： An access point in a geographic routing system and a controlling method thereof are provided. The controlling method of the access point in the geographic routing includes the following steps. A traffic event packet is received by the access point. A back-off timer of the access point is set to be a first back-off time value. The first back-off time value is less than a second back-off time value of any on board unit (OBU) which receives the traffic event packet. The traffic event packet is broadcasted by the access point when the back-off timer is counted down to be zero.
