Embodiment Construction
[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] figure 1 It is a flowchart of an embodiment of the delay-tolerant network routing method of the present invention, such as figure 1 As shown, the method of the present embodiment includes:
[0022] Step 101, the node carrying the message or message copy determines whether the node itself is an active node according to the current node activity of the node itself and the preset node classification threshold, if so, execute step 102, otherwise execute step 103;
[0023] Step 102, copying and forwarding the message or a copy of the message to other active nodes encountered;
[0024] Step 103: Forward the message or the copy of the message to other nodes encountered that are more active than the node itself, and delete the message or the copy of the message carried by the node itself.
[0025] In this embodiment, first define the node ac...
