Abstract: Aiming at the wide-region distribution and high complexity of the high-risk warehouse, a safety monitoring system based on the software defined wireless sensor network (SD-WSN) is designed.The system consists of wireless sensor nodes, controller and monitor software.In order to monitor environment inside the warehouse, the wireless sensor nodes are used for data acquisition by matching the flow table, the routing protocols and the sensor tasks can be configured by the central controller, environment data can be collected and graphically displayed by monitor software. In addition, monitor system can formulate sensor tasks through the interfaces provided by the controller. The reconfiguration of sensor nodes can be realized by updating the flow table. The testing results indicate that the designed system is programmable, can monitor the various safety indicators, and has good communication reliability.

Key words: software defined wireless sensor network, warehouse monitor, centralized management, programmable, communication reliability
