Method for designing a multi-unmanned aerial vehicle communication mode based on publish-subscribe

Abstract

The invention discloses a method for designing a multi-unmanned aerial vehicle communication mode based on publish-subscribe, which comprises the following steps of: (1) designing a topological structure of the communication mode by combining the structural characteristics of various publish-subscribe systems according to the requirements on dynamics and reliability during multi-unmanned aerial vehicle communication; step (2), abstracting the capability and state of the unmanned aerial vehicle as subscriptions, designing a subscription model of a communication mode, abstracting task targets and task constraints as events, and designing an event-subscription matching mechanism model of the communication mode; step (3), according to the subscription model and the event model designed in thestep (2), designing an event of a communication mode in combination with a demand for information real-time transmission in a multi-unmanned aerial vehicle communication process. The method has the advantages of dynamic property, reliability and loose coupling property, and can ensure that a plurality of unmanned aerial vehicles can still ensure certain communication quality in a complex and changeable battlefield environment.

Description

technical field [0001] The invention relates to the field of communication, in particular to a design method of a publish-subscribe-based multi-UAV communication mode. Background technique [0002] Unmanned Aerial Vehicle (UAV) is an unmanned aircraft controlled by radio remote control equipment or its own program control device. Due to its high flexibility and maneuverability, and its strong adaptability to harsh environments, it is widely used in Modern military and life fields have a wide range of applications, such as intelligence reconnaissance, military strikes, information countermeasures, data collection, weather monitoring, personnel search and rescue, etc. In the complex and changeable information battlefield environment, a single UAV is limited by many aspects such as the range of activities, load capacity, killing radius, and attack accuracy. With the continuous development of anti-UAV technology, a single UAV The combat capability of aircraft is declining day b...

Problems solved by technology

[0003] Multi-UAV cooperation for attack, reconnaissance, patrol and other tasks will inevitably face communication problems, and modern UAVs have different degrees of autonomy according to their models and uses. A UAV cluster is similar to a distributed system , can decompose a single complex task and send it to each drone, but the high flexibility and maneuverability of the drone makes the communication network change frequently, and the harsh environment on the battlefield makes the communication network must have a strong ability to survive. Different types of UAVs may have completely different hardware devices, which requires that the communication mode used in multi-UAV communication scenarios must be dynamic, reliable and loosely coupled. The publish-subscribe communication mode just meets the above characteristics
