摘　　要：水下移动无线传感器网络是追踪水下目标的重要手段,由于水下环境复杂,传感器节点会因为损坏或能量耗尽等问题脱离WSN网络,造成目标追踪困难。针对该问题,在拓扑熵理论基础上建立移动WSN目标追踪算法模型,利用拓扑熵对空间中点集拓扑关系描述移动WSN节点的部署情况。当有节点脱网后,通过不断计算拓扑熵值的变化合理调度节点移动,实现节点移动过程中的分布式自适应部署。仿真结果表明,在传感器节点损耗的情况下,提出算法和现有WSN目标追踪方法相比,在优化移动传感器网络的部署和目标追踪方面,具有更高的算法性能和效率。Underwater mobile wireless sensor networks are important means to track underwater targets.Due to the complex underwater environment,the sensor nodes can be detached from the WSN network because of the damage or energy depletion,causing difficulties in target tracking.To address this problem,a mobile WSN target tracking algorithm model was established based on topological entropy theory,and the deployment of mobile WSN nodes was described using topological entropy to the topological relationship of point sets in space.When there was a node of the network,the change of topological entropy value was continuously calculated to reasonably schedule the node movement,and to realize the distributed adaptive deployment during the node movement.Simulation results show that the proposed algorithm has higher algorithmic performance and efficiency in optimizing mobile sensor network deployment and target tracking compared with existing WSN target tracking methods in the presence of sensor node loss.
