Abstract：Most applications of WSN are based on the location information of nodes. The events monitored by WSN are closely related to the physical location information of nodes. Without location information, the monitoring data is meaningless, and the location information of nodes is closely related to network security. Therefore, the network security management of WSN is very important. This paper briefly describes the characteristics and applications of WSN, analyses the network security characteristics and requirements of WSN, and discusses two kinds of network security management mechanisms of WSN: key management and security location.
