Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] like figure 1 As shown, in a delay-tolerant network, when a congested node receives a storage request for a new message, the processing method of the present invention is applied. Its implementation steps are as follows:
[0032] (1) When a congested node in the delay-tolerant network receives a new message storage request, the congested node first judges the number of times the message is copied in the node memory, and chooses the method of message discarding or message transfer according to the number of copies ;
[0033] (2), when there is a message with the number of replications greater than the set threshold value in the congested node, then select the method of message discarding to alleviate node congestion; Files are discarded to alleviate node congestion;
[0034] (3), when there is no message whose number of time...
