Embodiment Construction

[0106] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0107] Such as figure 1 As shown, the present invention relates to a drone aggregation network system, including a central drone 100 and several business drones 200 . The central UAV 100 and the service UAV 200 form a UAV aggregation network with the central UAV 100 as the aggregation node. Each business UAV 200 serves as a client node in the UAV aggregation network. The service drone 200 as a client node transmits service data unidirectionally to the central drone 100 as a sink node. There is no business data transmission between business drones 200 . In order to realize the aggregation and transmission of business data from the above-mentioned business UAV 200 to the central UAV 100, the present invention divides the channel into time frames with the same time length in time, that is, the time frame is the division of channels with equal duration in time...

Abstract

The invention discloses a method and a device for allocating channel resources of an unmanned aerial vehicle convergence network. The method relates to the unmanned aerial vehicle convergence networkwhich is composed of a central unmanned aerial vehicle and a plurality of service unmanned aerial vehicles and takes the central unmanned aerial vehicle as a convergence node. When the central unmanned aerial vehicle communicates with each service unmanned aerial vehicle, the channel is divided into time frames at equal intervals in time, and each time frame is divided into time slots at equal intervals. The method is applied to a central unmanned aerial vehicle to allocate time slot resources of service transmission for each service unmanned aerial vehicle. According to the method, time slotresources are allocated to video services, and then time slot resources are allocated to non-video services. When resources are allocated and realized, the state of a wireless network is comprehensively considered, so the real-time performance and effectiveness of video services are ensured.

Description

technical field [0001] The invention relates to unmanned aerial vehicle network communication technology, in particular to the MAC protocol of the unmanned aerial vehicle network. Background technique [0002] The centralized network is a network composed of central nodes and client nodes. In the centralized network, the client nodes do not interact with the client nodes for business data, and the interaction of business data only occurs between the central node and the client nodes. During the period, the central node is responsible for the coordination of business data between client nodes and client nodes. An aggregation network is a special case of a centralized network. In an aggregation network, the central node is an aggregation node, and the service data of client nodes converges in one direction to the central node, and the central node receives business data in one direction from the client node. There is no interaction of business data between end nodes and clien...
