Embodiment Construction
[0030] Below in conjunction with accompanying drawing the embodiment of the present invention is described in detail: present embodiment is implemented on the premise of the method of the present invention, has provided detailed embodiment and concrete operation process, but protection scope of the present invention is not limited to following the embodiment.
[0031] The scene setting of this embodiment takes the vehicle-mounted Ad Hoc network on a highway as an example.
[0032] Step 1: When the source node has data to send to the destination node, a RREQ message will be generated, and the source node will add information such as its position, speed, direction, and route expiration time to the RREQ message and send it to neighboring nodes.
[0033] The source node adding information such as its own position, speed, direction, and route expiration time to the RREQ message refers to making certain modifications to the format of the RREQ message in order to meet the needs of st...
