Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The route-finding method in the scene of the fleet moving. The above method assigns the communication nodes in the fleet to node numbers, and clusters them according to the parity of the node numbers, so that the route-finding process first occurs in the same cluster, thereby obtaining better performance. Network performance, characterized by comprising the steps of:

[0025] (1) Number the fleet communication nodes one by one according to the sequence of the fleet;

[0026] In the fleet driving scenario, the fleet is generally composed of multiple echelons, each echelon contains multiple vehicles, and only one communication node is responsible for communicating with other echelons. The convoy is generally distributed in a chain during the march and the communication distance of the vehicle radio is greater than twice the actual distance between communication n...

Abstract

The invention discloses a routing way-finding method in a vehicle team travelling scene, and relates to the field of wireless mobile ad-hoc networks. According to the routing way-finding method disclosed by the invention, an on-demand distance vector routing algorithm and a clustering routing algorithm are effectively combined; according to the characteristics that communication nodes are in chainlike distribution in the vehicle team travelling scene and the communication distance of a vehicular radio station is two times greater than the practical distance among the communication nodes, the communication nodes are clustered; an on-demand distance vector routing protocol based on the odevity is provided; compared with the traditional routing algorithm, the routing way-finding method disclosed by the invention has the advantages that: the algorithm complexity is reduced; the routing overhead is reduced; the routing establishing time is reduced; and the network performance is relatively excellent.

Description

technical field [0001] The invention relates to a wireless mobile ad-hoc network routing protocol, which is especially suitable for the networking of mobile communication devices in the driving scene of a convoy, and has relatively excellent network performance. Background technique [0002] At present, the routing protocols of wireless mobile ad hoc networks are all designed for the random walk movement model, which cannot be well applied to the scene of convoy driving. Contents of the invention [0003] The purpose of the present invention is to provide a route-finding method aiming at the characteristics that the communication nodes are distributed in a chain and the communication distance of the vehicle-mounted radio station is greater than twice the actual distance between the communication nodes in the driving scene of the convoy. The invention ensures that the network has lower average time delay of the transmission layer, lower routing overhead and higher delivery ...
