The invention belongs to the technical field to mobile sensor network opportunity forwarding, and discloses a mobile sensor network opportunity forwarding method of a fire rescue scene. The method specifically comprises the following steps: S1, calculating a node stable value; S11, calculating the node stable value of a sensor node moving within a small range; S12, calculating the node stable value of a node formed by a fireman; S13, calculating the node stable value of a sensor node moving within a large range; S2, calculating the proportional relation among the nodes; and S3, formulating a forwarding strategy based on stability. According to the mobile sensor network opportunity forwarding method disclosed by the invention, the dynamics and the complexity of the fire rescue scene are considered, messages are forwarded by fully using the activity of the fireman node, and a relatively high transmission rate can be obtained in different network scales. Moreover, the mobile sensor network opportunity forwarding method disclosed by the invention is relatively small in network overhead and is suitable for the fire rescue scene.
