Abstract:

Compared with terrestrial network, the air-ground integrated network consisting of unmanned aerial vehicles (UAVs) and high altitude platforms (HAPs) offers the advantages of large coverage, high capacity, and seamless connection, which can provide effective communication services for the Internet of remote things (IoRT). In this paper, we investigate a joint packet scheduling, resource allocation and UAV trajectory design problem, with the objective of minimizing the average packet queue delay from HAP to IoRT devices in the air-ground integrated network. Because the problem is non-convex, we first reformulate it into a Markov decision process (MDP). And then, considering there are continuous and discrete hybrid action spaces in the MDP, we utilize the deep reinforcement learning (DRL) approach to design a hybrid multi-agent deep deterministic policy gradient-adaptive prioritized experience replay (MADDPG-APER) algorithm. Simulation results show that the proposed algorithm can reduce the average packet queue delay compared with other benchmark algorithms.
