Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] At present, most UAV ad hoc networks use the routing technology in the mobile ad hoc network, mainly including active routing technology, passive routing technology and hybrid routing technology. The active routing protocol periodically exchanges information with its nearby nodes through each node in the network, so as to update the topology information of each node to the ent...

Abstract

The invention provides a routing method of an unmanned aerial vehicle self-organized network. The routing method comprises the following steps: acquiring a network topological graph; acquiring a to-be-sent data packet and a target node thereof, combining the network topological graph and the target node, and acquiring all neighbor nodes communicated with the target node; acquiring the shortest path through which each neighbor node arrives at the target node; receiving broadcast information from each neighbor node, wherein the broadcast information at least comprises location information, cachequeue length information and residual energy information of the corresponding neighbor node; synthesizing the location information, the cache queue length information, the residual energy informationand the shortest path of each neighbor node, selecting the neighbor node used as a relay node, and transmitting a data packet to the relay node. The technical problem that the transmission path cannot be selected according to the specific situations of the unmanned aerial vehicle node in the prior art is solved.

Description

technical field [0001] The invention relates to the field of drive technology, in particular to a routing method for an ad hoc network of unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. [0003] With the continuous development of UAV-related technologies, UAVs have been more and more widely used in the field of communication. With the increasing complexity of the environment and business, a single UAV is difficult to meet the task requirements, and the UAV cluster can integrate and analyze the information obtained by each UAV node, and achieve the goal of accurate monitoring through multi-machine cooperation. A more comprehensive...
