| Abstract: | The rapid growth of data and the computing limitations of devices have spawned Mobile Edge Computing (MEC) solutions in Internet of Things. Among them, the high maneuverability, easy deployment and low cost of the Unmanned Aerial Vehicle (UAV) swarm and Multiple Input Multiple Output (MIMO) technology can enhance the transmission capacity and shorten the transmission delay in the MEC network. In this paper, the maximum total delay of the system are minimized by jointly optimizing the UAV trajectory, ground users’ratio of data offloaded, assisted UAV’s ratio of data offloaded and assisted UAV’sratio of data allocation in the multi-UAVs MIMO-MEC system, in which successive convex optimization technology and block coordinate descent method are used to solve the non-convex problem. The factors affecting the system delay are discussed, and the effectiveness and convergence of the algorithm is verified in the simulation results. |
