Problems solved by technology
[0005] In order to overcome the situation that the optimal node may change due to the fact that the existing routing method has not comprehensively considered the sending power of the sending end, the signal strength received by the receiving node, the delay, the number of hops, the moving speed of the node, and the direction of data transmission, etc. The existing routing methods are not suitable for the Internet of Vehicles environment. The present invention provides a method for optimal routing selection with different optimal nodes in consideration of signal strength, time delay, hop count, node moving speed, and data transmission direction.

Embodiment Construction
[0068] The present invention will be further described below in conjunction with the accompanying drawings.
[0069] refer to Figure 1 ~ Figure 3 , a routing optimization system for Internet of Vehicles, the routing optimization system includes an initialization setting module, a routing table building module, a desired sorting module, a link building module and a sending / receiving data packet module.
[0070] The initialization setting module is used for node maximum communication distance setting, transmission power setting, f value setting, k value setting; wherein, f represents the data transmission direction; the value of f is {0, 1}; the value of k is a preset value , its value is variable; the determination of this value is mainly related to the predetermined optimal communication node;
[0071] The routing table module is used to periodically broadcast / receive Hello messages for each node, and simultaneously establish and maintain a routing table according to the rec...

A routing optimization system for the Internet of Vehicles comprises an initialization setting module, a routing table building module, an expectation ordering module, a link establishing module and a data packet transmitting / receiving module. A routing optimization method includes following steps: step 1, performing initialization setting on a current node by each node; step 2, broadcasting a Hello message by each node, and building a routing table; step 3, calculating and ordering expectation values of nodes in the routing table by each node; step 4, establishing a communication link from a source node / middle node to a DCN (data communication network) node; step 5, enabling the source node / middle node to enter a data transmitting / receiving process; step 6, repeating the steps 2-5 until a data packet is successfully transmitted from the source node to a target node. The routing optimization system and method comprehensively considers different optimization routing options of optimal nodes in different circumstances of signal intensity, time delay, hop count, node moving speed and data transmission direction and is suitable for environment of the Internet of Vehicles.
Description
technical field [0001] The invention belongs to the technical field of Internet of Vehicles routing, and in particular relates to a routing optimization system and method under the background of Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a communication network formed by the application of the Internet of Things in automobiles. It is a new type of network that can realize vehicle-to-vehicle, vehicle-to-human, vehicle-to-road, and human-to-human communication. As a new type of communication network, the Internet of Vehicles has the characteristics of fast node movement, predictable node movement direction, real-time coordinates and speed, large density changes, and large coverage area. [0003] As a new type of communication network, the Internet of Vehicles has many characteristics that make the network similar to the mobile Ad Hoc network, but has its own characteristics. Therefore, the routing protocols for traditional mobile Ad Hoc ar...
