Abstract

The invention discloses a routing method and system for an unmanned aerial vehicle (UAV) self-organizing network. The routing method for a UAV self-organizing network comprises the following steps: sending data from a source node to a destination node layer by layer according to a routing information table; in the data sending process, if the route on the path selected by a forwarding node fails,calculating service-of-quality heuristic function values of all neighbor nodes of the forwarding node, and selecting an intermediate node according to the service-of-quality heuristic function values;detecting whether the routing information table stored by the selected intermediate node has target routing information arriving at the destination node; and if having, using the intermediate node asa next hop node, and continuing to send the data to the destination node layer by layer until all the data reaches the destination node. The method can ensure the stability of data transmission during the process of sending data from the source node to the destination node, fully exerts the air superiority of the UAV, and ensures the continuous validity and timeliness of data transmission.

Description

technical field [0001] The invention relates to a routing method for an unmanned aerial vehicle ad hoc network and a routing system for realizing the method, belonging to the technical field of an unmanned aerial vehicle ad hoc network. Background technique [0002] Search drones can be used in many rescue situations. The purpose of the search is to check for survivors in the target area. The use of search drones can transmit the information of the target area to the control center in real time, so that rescuers can take appropriate actions in the next step to quickly complete the task. Therefore, the research of search UAV has important practical value, and has been highly valued by the United States, Japan, Australia, China and other countries in recent years. [0003] The UAV performing the search mission moves randomly within a certain range of airspace. When the network infrastructure is unavailable due to natural disasters, the UAV Ad Hoc Network can be used to tran...
