The invention relates to a mobile perception data routing method for MWSNs (Mobile Wireless Sensor Networks). The mobile perception data routing method comprises a data collecting step of a static Sink node and a data routing step of a mobile sensor node. Through adopting the mobile perception data routing method, when the mobile sensor node is nearby the Sink node and can find a path of the Sinknode, data are sent to the Sink node via a collection tree in multi-hop manner; when the mobile sensor node does not find the path of the Sink node, two conditions on whether a Sink node bit is learntare analyzed, different transmission probability calculation formulas and a method of delaying data of other mobile sensor nodes are proposed, and the data are sent to the Sink node by opportunisticrouting. According to the mobile perception data routing method, the problem of data reporting of the mobile sensor node is solved, the data transmission quantity is improved, the redundancy rate andthe node energy consumption
