Dynamic Cooperative Deployment of Emergency Internet of Things Near Ground Space Based on Drone

Aiming at the reliable, energy-saving and long-distance transmission requirement of key areas information, without ground base station and limited energy, the long-distance communication problem of a mobile Ad-Hoc network based on multi-drones in the near ground space as emergency Internet of things (eIoT) is studied. A dynamic cooperative deployment method based on drone was proposed. First, model this type of eIoT. Second, given drones' formation scattered in large area, in formation, and moved slowly, energy consumption of communication and movement was calculated as a quadratic programming problem with quadratic constraint. Third, according to the Gerschgorin disc theorem and the existence theorem of the root, the problem above was proved as a convex optimization problem. So the optimal path point of the mobile earth station could be obtained. Dynamic cooperative deployment of eIoT near ground space was realized. Finally, from transferring to moving energy consumption, the effect of the proposed method was verified through experiments. At the same time, the factors that affect the effectiveness of the methods were also analyzed.
