Embodiment Construction

[0050] A multi-channel and multi-path routing protocol for fleet ad hoc network of the present invention will be further described below in conjunction with accompanying drawings and examples, but the implementation and protection scope of the present invention are not limited thereto.

[0051] All fleet vehicles using this method are equipped with an embedded platform, GPS module, wireless communication module, camera, microphone. Among them, the GPS module provides position, speed, and movement direction information for the vehicle; the wireless communication module contains two network interfaces and supports IEEE802.11p protocol; the camera and microphone are used for voice and video calls; each module is connected to the embedded platform through the interface. The embedded platform is equipped with electronic navigation map software, and the electronic navigation map can display the positions of other vehicles in the fleet through the self-adaptive distributed location se...

Abstract

The invention discloses a multi-channel multi-path routing protocol for vehicle team ad-hoc networks. The multi-channel multi-path routing protocol mainly comprises: (1) each vehicle node is made to work on a service channel, the vehicle nodes using the same service channel form a channel transmission path in a vehicle team, and multiple transmission paths of multiple channels are formed in the vehicle team; (2) each vehicle node acquires position, speed and motion direction information of other vehicle nodes through an adaptive distributed position service; and (3) a multi-channel greedy forwarding algorithm is adopted: when the vehicle nodes send or forward a data message, a next-hop neighbor node is selected by use of the greedy forwarding algorithm according to the position of a destination node and the working channel utilization rate of a neighbor node until the data message reaches the destination node. By adopting the provided multi-channel multi-path routing protocol for vehicle team ad-hoc networks, vehicle team communication is enabled to be fully self-organized without relying on any infrastructure, adjacent vehicle nodes are allowed to communicate on different channel transmission paths at the same moment, the network throughput is improved, and the routing protocol supports multi-hop big data transmission and has practical application prospects.

Description

technical field [0001] The invention relates to a vehicle ad hoc network technology, in particular to a routing protocol for a fleet ad hoc network. Background technique [0002] A fleet is a collection of vehicle nodes that travel together. Common fleets include self-driving tour fleets, logistics fleets, and official fleets. As cars play an increasingly important role in people's lives, people's demand for communication between vehicles during driving is also increasing. Using vehicle-to-vehicle communication technology, team members can learn about the location of other members, and perform applications such as transaction notification, video calls, and file transfers between vehicles. At present, the communication methods of the fleet mainly include mobile phone and radio communication. Mobile phones have become a popular communication method. However, mobile phone communication is not only costly, but also cannot meet the communication requirements in the fast-moving ...
