DTN routing method based on reliable information distribution
It is a technology of information distribution, tolerance of delay and tolerance, applied in the direction of data exchange network, digital transmission system, electrical components, etc., which can solve the problems of insufficient intelligence of control strategy, limited message copy, and less research on auxiliary facility routing strategy. Achieve the effect of increasing the probability of successful message transmission, increasing the message transmission ratio, and avoiding network congestion

Embodiment Construction
[0073] Further description will be made below in conjunction with the accompanying drawings.
[0074] The invention relates to a delay-tolerant and fault-tolerant network routing method based on reliable information distribution, including the following measures:
[0075] 1. Intelligent and dynamic control of the number of message copies (copies)
[0076] Three layers of threshold / proportional values (BUSY), (NORM_NODE_PERCENT), (NORM_NODE_DISTANCE) are used for control to realize automatic classification and queuing of neighbor nodes, and divide neighbor nodes into two queues, common and resource-constrained, and use different queues for different queues Packet copy quantity control policy. in:
[0077] For ordinary queues, the three-layer threshold / proportion value is used to filter in sequence. First, the original queue is selected according to the BUSY value, and then the nodes with the largest remaining capacity in the original queue are selected to form a new queue. ...
