Modeling of Wireless Sensor Nodes Airdrop in Wind Field

In recent years, more and more research and applications use The Unmanned Aerial Vehicle (UAV) airdrop sensor nodes to deploy and maintain large wireless sensor networks (WSN). However, the problem of increasing the energy consumption of the node communication and even deviating from the monitoring range caused by the deviation of the airdrop node cannot be ignored. In this paper, by studying the variation of the wind’s characteristic parameters with height and geomorphology, the wind force received by the airdrop node at any height of any landform is obtained, and then the model of the motion process of the airdrop node in the horizontal and vertical directions is established. Finally, the range of deviation caused by UAV seeding sensor nodes at any altitude under wind force is simulated. The influence of the error of air airdropping nodes is discussed, and an executable solution is proposed.
