DDPG-based optimization for latency variant offloading schemes with heterogeneous IoT terminals under collaborative EDGE

Year: 2025

Type: article

Abstract: We address the issues of difference in latency tolerance with heterogeneous IoT users from ground and aviation space by proposing a collaborative satellite terrestrial EDGE computing network. Based on the variability in latency tolerance we propose three offloading schemes under two distinctive scenarios. Optimization in resource sharing while offloading is carried out by adopting DDPG-based actor-critic framework which is suggested as a suitable algorithm by recent studies. We validated the schemes evaluating four performance parameters. Results showed that schemes that tolerate delays between 0.25 to 2.00 seconds outperformed other schemes in terms of reward, delay and energy consumption.
