Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] like figure 1 As shown, the present invention provides a method for alleviating control channel synchronization conflicts in the multi-channel transmission of the vehicle ad hoc network. The method optimizes and improves the control channel transmission mechanism for multi-channel transmission in the original IEEE1609. Adapt to the channel load distribution algorithm, so that nodes can decide whether to send messages immediately according to the current channel conditions, so as to effectively alleviate channel conflicts and reduce message collisions.
[0026] Whenever a new transmission slot is entered, the channel first needs to be initialized. The main work completed during the initialization period is switching of physical channels and timing synchronization. This period is called the guard interval GI of the system. In GI, the physical channel i...
