It was determined that the following strategies can be used to deploy a swarm of UAVs from a stationary depot to form a flying LiFi network in a room with obstacles: strategy 1a, which involves the movement of each UAV from the depot to the first point of the LiFi route and further deployment of the network within it; strategy 1b, which involves the movement of each UAV from the depot immediately to the destination point on the LiFi route; strategy 1c, which involves the movement of each UAV from the depot to a point as close as possible to the middle of the LiFi route, and further deployment of the network within it.
It is shown that the work cycle of one UAV swarm shift for deploying and ensuring the functioning of the LiFi network consists of the following stages: departure from the depot and approach to specified points on the laid LiFi route; network settings; data transmission; return to the depot; waiting for the next work cycle.
A graphical interpretation of the alternating work of two UAV shifts to deploy and ensure uninterrupted functioning of the flying LiFi network is provided, according to which the UAVs of the next shift arrive and configure the network formed by them before the UAV of the current shift starts moving to the depot.
With the use of the developed software, it was calculated that the uninterrupted functioning of the flying LiFi network with a YBR not lower than = 0.99875 for 180 minutes can be ensured by two shifts, each of which performs three work cycles and consists of 6 UAVs with a failure rate of = 0.0005 1/h.
Methods are proposed and examples are given to ensure the uninterrupted functioning of a flying LiFi network with the required level of reliability for a given time in a room with obstacles by using two UAV swarm shifts.
A graphical interpretation of the alternate operation of two UAV swarm shifts for the deployment and uninterrupted operation of a flying LiFi network is provided.
