摘　　要：【目的】为达到增强无线异构传感器网络(HWSN)三维覆盖能力的目的,提出了一种基于改进蜜獾优化算法(IHBA)的无线异构传感器网络三维部署方法。【方法】首先,结合自适应果蝇优化算法,增强算法的随机搜索性,便于算法得到全局最优解,然后引入替换最差个体策略,避免适应度过低的个体占据种群位置,提高算法收敛速度,同时引入新个体提高种群多样性,避免算法个体早熟。【结果】将该算法应用于无线异构传感器网络的覆盖优化,相比标准蜜獾算法,其网络覆盖率提升18.1%。【结论】仿真结果表明,该算法收敛速度更快,可以有效提高无线异构传感器的网络覆盖能力,整个网络的节点分布也更加均匀。【Objective】In order to enhance the 3D coverage capability of wireless heterogeneous sensor networks(HWSN),a 3D deployment method based on improved honey badger optimization algorithm(IHBA)is proposed.【Method】Firstly,combined with the adaptive fruit fly optimization algorithm,the random search ability of the algorithm is enhanced,which is convenient for the algorithm to obtain the global optimal solution.Then,the strategy of replacing the worst individual is introduced to avoid the low adapting individual to occupy the population position and improve algorithm convergence speed.In the meantime,new individuals are introduced to improve the population diversity and avoid the individual prematurity of the algorithm.【Result】This algorithm is applied to the coverage optimization of HWSN,and the network coverage is improved by 18.1%compared with the standard Honey Badger algorithm.【Conclusion】The simulation results show that the algorithm converges faster,can effectively improve the network coverage capability of wireless heterogeneous sensors,and the node distribution of the whole network is more uniform.
