Probabilistic routing method with limited time delay based on intermittent communicated self-organizing network

The invention provides a probability routing method applied in a discontinuously connected self-organizing network. The basic thought of the invention is as follows: judgment is made in advance whether to generate a message copy by utilization of the statistic distribution rules for node movement in the discontinuously connected self-organizing network and according to the required transmission probability RDP and transmission delay determined by a user message; the value of the required transmission probability RDP of the message copy generated is calculated; and the RDP value in the source message is updated. The method guarantees capability of transmitting the message within the determined forwarding time, meets the required transmission probability (RDP) value anticipated by a user, can control the transmission charges of the message according to the RDP value and the forwarding time requirement, gets rid of unnecessary message forwarding, and then effectively reduces the message transmission charges in the discontinuously connected self-organizing network.
