Abstract

The invention discloses a routing method in a vehicle wireless communication network. The method disclosed by the invention comprises the following steps: route establishment: carrying out a route request and a route response, establishing a fixed node at the crossing, namely an anchor point and establishing an anchor point route on the anchor point; route transmission: carrying out the route transmission by adopting the adaptive broadcasting based on a chain prediction mechanism and a transmission algorithm based on the chain prediction mechanism; and route maintenance. The invention also discloses the vehicle wireless communication network. In the vehicle wireless communication network disclosed by the invention, a wireless communication module loading a special short-distance communication protocol is installed on each vehicle to jointly form a distributed ad hoc network; each vehicle forms a node; a fixed static wireless node is installed at the crossing; the static wireless node serves as the anchor point through the wireless communication module loading the special short-distance communication protocol and is used for assisting the node communication on the route or collecting the information of the crossing; and the anchor point and the nodes on the road jointly form the vehicle wireless communication network.

Description

technical field [0001] The invention relates to the field of vehicle wireless communication, in particular to a routing method in a vehicle wireless communication network and a vehicle wireless communication network, and can be widely used in vehicle wireless communication networks with multi-hop vehicle nodes. Background technique [0002] Under the future intelligent transportation system, as an emerging vehicle communication technology, Vehicular Ad hoc Network (VANET) proposes a new generation of wireless communication technology suitable for the vehicle wireless environment, providing seamless communication for mobile users on the vehicle. The connection service can realize multi-hop wireless communication between vehicles and between vehicles and roadside infrastructure, and provide vehicles with a variety of safety applications (such as assisting traffic management, collision prediction, etc.) and non-safety applications (such as road condition instructions, Internet ...
