🤖 AI Summary
To address trajectory optimization for drone swarms in post-disaster complex environments, this paper proposes an autonomous cooperative planning method integrating Henry Gas Solubility Optimization (HGO) with a Cluster Optimization Scheme (COS), jointly minimizing transportation cost and computational overhead while ensuring shortest path length and flight time. This work pioneers the application of HGO to drone trajectory optimization and enhances population diversity and local search capability via COS, significantly improving convergence speed and robustness. Extensive simulations across four scenarios—typical, constrained, entangled, and highly complex—demonstrate superior performance over mainstream algorithms including PSO, GWO, CSA, and BMO: in typical environments, transportation cost is reduced by 39.3% and computational time by 16.8%. The results validate the method’s efficacy and practicality for emergency communication and rescue missions.
📝 Abstract
The unmanned aerial vehicles (UAVs) in a disaster-prone environment plays important role in assisting the rescue services and providing the internet connectivity with the outside world. However, in such a complex environment the selection of optimum trajectory of UAVs is of utmost importance. UAV trajectory optimization deals with finding the shortest path in the minimal possible time. In this paper, a cluster optimization scheme (COS) is proposed using the Henry gas optimization (HGO) metaheuristic algorithm to identify the shortest path having minimal transportation cost and algorithm complexity. The mathematical model is designed for COS using the HGO algorithm and compared with the state-of-the-art metaheuristic algorithms such as particle swarm optimization (PSO), grey wolf optimization (GWO), cuckoo search algorithm (CSA) and barnacles mating optimizer (BMO). In order to prove the robustness of the proposed model, four different scenarios are evaluated that includes ambient environment, constrict environment, tangled environment, and complex environment. In all the aforementioned scenarios, the HGO algorithm outperforms the existing algorithms. Particularly, in the ambient environment, the HGO algorithm achieves a 39.3% reduction in transportation cost and a 16.8% reduction in computational time as compared to the PSO algorithm. Hence, the HGO algorithm can be used for autonomous trajectory optimization of UAVs in smart cities.
