Embodiment

[0077] 1, network level

[0078] Clearance TS:

[0079]

[0080] TNN i (t) For the Time Grounding Station or UAV node and the data transfer delay in the entire network node, the current ternation station or the path RNN within the UAV node i (t) value is 0;

[0081] BW i (t) is an estimated available bandwidth of Time path i;

[0082] RTT i (t) The average round-trip time measured for T time path I;

[0083] RT i (t) is the retransmission ratio of Time path I statistics;

[0084] Ns i (t) The health status of the node where the T time I path (health value includes: node electricity, no other business), the higher the health value, the greater this value.

[0085] The multiplier α, β, γ, θ, λ represent the time delay, bandwidth, end-to-end delay, retransmission rate, and health calculation in path weight calculations, respectively; these 5 parameters can be based on users Demand is configured and modified. It can be seen that the smaller the value of TS is seen by formula, the be...

Abstract

The invention belongs to the technical field of wireless data transmission, and discloses an unmanned aerial vehicle formation data transmission path switching method and system, a medium and a terminal, and the unmanned aerial vehicle formation data transmission path switching method in a collaborative heterogeneous convergence access network comprises the following steps: calculating the networkflux; establishing an available transmission path pool; and switching a path. According to the wireless data transmission path switching method in the unmanned aerial vehicle formation cooperative heterogeneous convergence access network, the unmanned aerial vehicle cooperative heterogeneous convergence access network and the densely deployed sensor network nodes are used as the support, and theaim of improving the wireless data transmission discontinuity of the unmanned aerial vehicles is achieved. By using the method of timely switching the transmission path after the current transmissionpath is blocked or interrupted, the timely, accurate and reliable completion of the communication between the ground station and the unmanned aerial vehicle and the related nodes is ensured.

Description

Technical field [0001] The present invention belongs to the field of wireless data transmission, and more particularly to a process of drone aquamer data transmission path switching method, system, medium, and terminal. Background technique [0002] At present, with the development of drone technology, drone real-time status monitoring and techniques for drone remote control are increasingly attached to the aviation field. Data interactions with high real-time in drones and ground stations are very important needs in the aviation sector. Unmanned Complex homework is very fast in recent years, regardless of various commercial drone formation performances, industrial-grade drone clusters, military-grade drone clusters, and unmanned opportunities are more increasing in various fields. universal. Similarly, the importance of data communication before the drone cluster and the ground station is self-evident. Since the internal networking network background flow of the drone formation ...
