摘要： Wi-Fi based position information communicating methods, vehicle mounted communication devices, and pedestrian devices are provided. One of the methods includes: a communication device mounted on a first vehicle determining whether position information of a second vehicle, whose distance to the first vehicle is shorter than a first predetermined distance, is received within a first predefined time period; and if no, broadcasting position information of the first vehicle in a first 802.11 management frame. By employing the methods, pedestrian detection rate may be improved and wireless channel congestion may be mitigated.

摘要： A method and a system for communicating a high priority message in a vehicular ad hoc network is provided. In the communication channel, time slots are defined, and N successive time slots constitute one cycle, where m th time slot of each cycle is reserved for transmitting a pre-emption message. The method may include: selecting a sub-frame, transmitted in a first q th time slot, having a priority lower than that of the high priority message; transmitting in a first m th time slot after the first q th time slot a pre-emption message indicating that a second q th time slot, which is after the first m th time slot, will be occupied to transmit the high priority message; and transmitting in the second q th time slot the high priority message. By using the method and system, messages with higher priority can be transmitted timely even under very congested conditions.
