Problems solved by technology
[0003] At present, many routing mechanism schemes for DTN networks have been proposed, starting from the original copy-based routing protocol and context-based routing protocol. The impact of node relationship and node mobility on routing protocols; the Bubble routing algorithm is based on human social relationships, and selects appropriate forwarding nodes based on community structure and node distribution, because it always looks for nodes with high node distribution density to forward messages , nodes with low node distribution density cannot obtain the opportunity to forward messages, thus causing a waste of node resources. In addition, for large-scale networks, the problem of saving too many copies of this routing algorithm will also cause relatively large overhead; prior art The routing algorithm in has the problem of high network transmission delay

Embodiment Construction
[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0069] The embodiment of the present invention discloses a network data routing method, see figure 1 As shown, the method includes:
[0070] S11: the first forwarding node judges whether it is the destination node, if yes, enters S12, otherwise, enters S13.
[0071] It should be noted that, in addition to the source node, each node in the data routing process first needs to determine whether it is a destination node in order to decide which step to trigger in...

This application discloses a network data routing method, system and device, which divides each node in the network into communities in advance, judges whether the first forwarding node and the destination node are in the same community, and optimizes the data packet forwarding route. A forwarding node directly forwards the data packet to the second forwarding node with the highest node activity in the first community. If not, the first forwarding node judges whether it is connected to an external community. Internally forward the data packet to the second forwarding node, so that the data packet can be forwarded from the first community to the external community as soon as possible. If connected, the first forwarding node will calculate the community closeness between the communities. The first forwarding node The second community with the highest closeness to the first community is used as the community to be forwarded, so as to optimize the forwarding path and shorten the delay. On this basis, the first forwarding node forwards the data packet to the second forwarding node to realize the forwarding path. optimization.
Description
technical field [0001] The invention relates to the field of network data transmission, in particular to a network data routing method, system and device. Background technique [0002] DTN is an emerging research field, it is a general message-oriented reliable overlay network architecture proposed by Kevin et al. Problems such as frequent network disconnection, high latency and heterogeneity in the network. The characteristic of the DTN network is that there is no need for a complete path between the source node and the target node. Taking advantage of the characteristics of the mobile node, the "store-carry-forward" routing mechanism is adopted to realize the network communication network. Due to the particularity of the DTN network structure, the DTN The research and development will provide powerful scientific theory and technical support for message interaction in the fields of military warfare, aerospace communications, disaster recovery, emergency rescue, etc., and w...
