Problems solved by technology

[0010] On the other hand, the existing trajectory planning schemes cannot adapt to the characteristics of the stratosphere. Therefore, it is necessary to design the trajectory planning algorithm according to the characteristics of the stratosphere, such as flight altitude and atmospheric environment.

Embodiment Construction

[0039] Below, combine figure 1 with figure 2 The present invention will be further explained.

[0040] A stratospheric active routing design method based on a time-delay-tolerant interruption-tolerant network, and its specific implementation includes the following steps:

[0041] (1) Collect the basic information of the delay-tolerant interruption-tolerant network; the basic information of the delay-tolerant interruption tolerant network includes nodes, the degree of nodes, the edges between nodes, the length of edges, and TTL time.

[0042] (2) Using a clustering algorithm, divide all nodes in the entire network into several disjoint cells based on geographic location and transmission delay, and select one node in each cell as the sink node;

[0043] Among them, step (2) specifically includes the following steps:

[0044] (201) Obtain the connection relationship of all nodes in the entire network and generate a data set; the data set includes: nodes, edges between nodes, node degrees...

Abstract

The invention discloses a stratospheric active routing design method based on a delay / disruption tolerant network. The active routing process is conducted in a manner of clustering, layering and cruising by unmanned aerial vehicles. The method comprises the following steps: firstly, dividing a user node into a plurality of mutually disjointed regions according to geographic positions through a clustering algorithm, and selecting an aggregation node of each region; secondly, sending the message to the aggregation node through the unmanned aerial vehicle in the region when a node in the region hopes to send a message to a user outside the region; thirdly, cruising the aggregation nodes through the unmanned aerial vehicle in the whole network; finally, uploading a message that a destination does not belong to the region to the unmanned aerial vehicle through the aggregation nodes when the unmanned aerial vehicle in the whole network passes through the aggregation nodes, forwarding the message to the aggregation node of the destination region thorugh the unmanned aerial vehicle in the whole network, and forwarding the message to the destination node through the unmanned aerial vehicle of the destination aggregation node.

Description

Technical field [0001] The invention relates to an active routing design method for a restricted network, in particular to a stratospheric active routing design method based on a delay tolerant and interruption tolerant (DTN) network. Background technique [0002] Delay / Disruption Tolerant Networks (Delay / Disruption Tolerant Networks), abbreviated as DTN, is a computer network architecture method that aims to solve the lack of sustainable network connections or long transmission delays in heterogeneous networks The problem of reliable data transmission. [0003] DTN network is a type of network form without a stable end-to-end transmission path. It consists of a group of mobile hosts with wireless receiving devices and can communicate with each other without relying on infrastructure control. This type of network is also called a restricted network, and its characteristics include: long or variable delay, intermittent connections, asymmetric data transmission rate and high data li...
