Embodiment 1

[0082] Step 1, the source node broadcasts the data packet, and the neighbor nodes of the source node in the UAV ad hoc network receive the data packet;

[0083] The drone NID of the source node identity 1 Broadcast the second packet data 2 , the set of neighbor nodes Each UAV in receives the data packet data 2 , and record the node-receiving information.

[0084] Second UAV NID 2 Receive packet data 2 After the node - the received information is denoted as Indicates the packet data 2 by Drone NID 1 initiated, NID for drones 2 received packet data 2 time. Using Signal-to-Interference-to-Noise Ratio (SINR) for UAV NID 2 Receive packet data 2 Calculate the signal quality of the data packet data 2 The SINR value of is denoted as If the value is 1907.500, it can be found that it belongs to the corresponding group pair_2 according to Table 1.

[0085] Third Drone NID 3 Receive packet data 2 After the node - the received information is denoted as NID for...

Abstract

The invention discloses a limited flooding forwarding method for data packets in an unmanned aerial vehicle ad hoc network. According to the method, the forwarding delay is determined by calculating the signal-to-interference-noise ratio (SINR) when a data packet is received, and a delay forwarding queue is established in a network node, so that forwarding conflicts are reduced, and flooding is limited. The method specifically comprises the following steps: calculating delay time according to an SINR value after neighbor nodes except a source node receive a data packet; inserting the data packet into a delay queue according to the delay time; when the timer is overtime, forwarding the data packet; if the same data packet is received before timeout of the timer, deleting the data packet in the queue, and canceling forwarding at the same time. According to the method, redundant transmission during flooding of the data packet can be effectively reduced, and the purpose of improving the delivery success rate of the data packet is achieved.

Description

technical field [0001] The present invention relates to a forwarding method for flooding data packets in an unmanned aerial vehicle ad hoc network, more particularly, a method for limiting flooding forwarding of data packets in an unmanned aerial vehicle ad hoc network based on the signal-to-interference-to-noise ratio. Background technique [0002] The UAV swarm is supported by the ability of a single UAV, centered on the information communication network, centered on swarm intelligence, and coordinated and interacted with UAVs as a means to comprehensively integrate a large number of UAV functions based on an open architecture , to achieve a substantial improvement in the overall performance of the UAV cluster, with the advantages of strong invulnerability, low cost, distributed functions, and flexible use. Therefore, UAV swarms are widely regarded as a "Game-Changing" disruptive technology and a force multiplier on the modern battlefield. In recent years, it has attracted...
