The application range and application scenarios of wireless sensor networks are gradually expanding.Wireless sensor networks play an important role in applications such as environmental detection,military tracking,and space exploration.The positioning of unknown nodes in the network is the premise of the practical application of wireless sensor networks.This paper first expounds the structure of wireless sensor networks and the importance of location technology in the practical application of wireless sensor networks.Then,the basic positioning algorithm and its principle are introduced for the location problem of wireless sensor networks.The calculation of classical MDS algorithm is too large.The error is easy to accumulate.This paper proposes a distributed positioning algorithm based on MDS-MAP.The method utilizes the connectivity relationship of the network nodes to locate the node position under the condition that the ranging accuracy between the nodes is not high,and reduces the computational complexity and energy consumption in the node positioning process.The positioning effect of the algorithm in different propagation models is simulated.Then the algorithm is applied to the mobile anchor node,and a moving anchor node planning path based on circular trajectory is proposed.By comparing the moving path with other path algorithms in power consumption and positioning accuracy,it is proved that the moving trajectory can reduce the running power of the moving anchor node during positioning,effectively avoid the interference of obstacles in the network,and provide higher positioning.Precision.Finally,the proposed path planning using mobile anchor node location algorithm and mobile anchor node is applied in the logistics engineering scenario,and a disaster search and rescue system is described.
