Wireless sensor network system based on dynamic routing and method thereof

The invention provides a wireless sensor network system based on dynamic routing, wherein the system is used for the industry. The wireless sensor network system based on dynamic routing comprises a source node cluster, a relay node cluster, a sink node and a control center, and a routing link is composed of a cluster head node of the source node cluster, a cluster head node of the relay node cluster and the sink node. In the idle stage of an industrial network, a test is performed on the link to acquire link quality data, the cluster head nodes are selected according to the link quality data, and a routing link is dynamically selected. According to the wireless sensor network system based on dynamic routing and a dynamic routing selecting method of the system, a clustering structure is provided, a work node is divided into multiple modules, and thus the work node can be suitable for characteristics of the process industry. The periodization characteristic of the process industry is considered, the link test is completed in the idle time slot of the process industry, so that the routing link is dynamically selected, and the reliability of sensor network data transmission is improved. A data retransmission mechanism and an emergency mechanism are introduced, and thus sudden change of environment and other problems can be effectively handled.
