Problems solved by technology

[0003] The current IP routing mainly implements various routing algorithms based on the IP address of the destination node. In the V2X network, because each vehicle node is moving rapidly, its IP node has no specific relationship with the actual network node location, so , the routing algorithm targeting the IP address will face great challenges when applied to the V2X network

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] In the V2X network, each node regularly broadcasts heartbeat information including vehicle location, status, IP address and other self-status information to surrounding nodes, and each node receives heartbeat information sent by other surrounding nodes at the same time. Based on the received heartbeat information, update and maintenance include: The environment information column of the surrounding node related information.

[0015] The geographic location routing method based on the vehicle-mounted short-distance communication network disclosed in the present invention deploys a geographic location storage node for storing node geographic location information in a V2X network, and is used for establishing roadside nodes according to the roadside node geographic location and IP address. The geographic location routing nodes for routing ...

Abstract

The invention discloses a vehicle-mounted short-distance communication network based geographic position routing method. Geographic position storage nodes and geographic position routing nodes are deployed in a V2X network, and road-side nodes send geographic position information of all vehicle-mounted nodes to the geographic position storage nodes for storage. Data packs sent by source nodes are transmitted to source road-side nodes in a flooding mode, the source road-side nodes receives requests and then sends the geographic position information of destination nodes to the geographic position routing nodes, the geographic position routing nodes looks for the geographic position storage nodes and obtains the geographic position information of the road-side nodes which the destination nodes belong to according to the geographic position information of the destination nodes and then establish routing between the source road-side nodes and the destination road-side nodes, established routing information is sent to the source road-side nodes, the source road-side nodes sends the data packs of the source nodes to the destination road-side nodes, and the destination road-side nodes send the data packs in a flooding mode. The vehicle-mounted short-distance communication network based geographic position routing method can achieve quick data transmission among nodes.

Description

technical field [0001] The invention relates to a geographic location routing method based on a vehicle-mounted short-distance communication network, and belongs to the technical field of vehicle-mounted communication networks. Background technique [0002] Vehicle to X (Vehicle to X: V2X) network is the communication within the vehicle, vehicle road, workshop, outside the vehicle, and between people and vehicles through short-range communication technologies such as wireless communication, GPS / GIS, and sensors. Each node in the network is in a state of rapid movement, and its network switches frequently, so the network communication between nodes needs to use special routing discovery, establishment and maintenance methods. [0003] The current IP routing mainly implements various routing algorithms based on the IP address of the destination node. In the V2X network, because each vehicle node is moving rapidly, its IP node has no specific relationship with the actual networ...
