摘　　要：针对三维无线传感器网络在传感器节点重新部署时,由于复杂和恶劣环境导致的传感器节点电池充电和恢复困难的问题,提出了一种基于蝙蝠优化器的三维无线传感器网络节能覆盖增强策略。首先,利用截角八面体对三维环境进行无缝叠加,将覆盖增强和能量优化问题转化为将节点移动到截角八面体的任务分配问题;其次,基于蝙蝠优化器实现无线传感器网络的最小化总能耗和平衡剩余能量的多目标优化;最后,通过建立仿真模型,与虚拟力导向粒子群优化算法、三维虚拟力算法、及匈牙利算法进行对比分析,验证策略的有效性与可靠性。实验结果表明:所提策略能使节点剩余能量的均匀性分别提高30.53%、43.44%和32.03%,同时能有效降低节点总能耗,并在最大能耗节点的能耗、最终覆盖率和时间消耗方面表现良好,具有较高的可靠性和准确性。Aiming at the difficulty of charging and recovering the battery of the sensor node due to the complex and harsh environment when the sensor node is redeployed in the 3 D wireless sensor network,a 3 D wireless sensor network energy-saving coverage enhancement strategy based on the bat optimizer is proposed.First,use truncated octahedrons to seamlessly overlay the three-dimensional environment,and transform the coverage enhancement and energy optimization problems into task assignment problems of moving nodes to truncated octahedrons;secondly,based on the bat optimizer,the wireless sensor network Multi-objective optimization for minimizing total energy consumption and balancing remaining energy;finally,by establishing a simulation model,comparing and analyzing the virtual force-oriented particle swarm optimization algorithm,3 D virtual force algorithm,and Hungary algorithm to verify the effectiveness and reliability of the strategy.Experimental results show that the proposed strategy can increase the uniformity of the remaining energy of the node by 30.53%,43.44%and 32.03%,and can effectively reduce the total energy consumption of the node,and the energy consumption,final coverage and time of the node with the largest energy consumption Good performance in terms of consumption,with high reliability and accuracy.
