Embodiment Construction

[0020] The technical solution of the present invention will be described in further detail below through specific embodiments and accompanying drawings.

[0021] figure 1 A schematic flowchart of an embodiment of a routing method for a delay-tolerant network provided by the present invention. Such as figure 1 As shown, the method may specifically include:

[0022] S101, the node carrying the message determines its own node type according to the source of the message.

[0023] Specifically, if the node carrying the message judges that the message is generated by itself, it determines that its own node type is the source node. If the node carrying the message judges that the message is forwarded to itself by other nodes, it determines that its own node type is an intermediate node.

[0024] S102. If the node carrying the message determines that its own node type is a source node, forward the message to an encountered neighboring node.

[0025] Specifically, if the node carr...

Abstract

The invention provides a routing method, equipment and system for a delay tolerant network. The method includes: the node type of a node carrying a message is determined according to the source of the message; if the node carrying the message is a source node, the message is forwarded to every met adjacent node; if the node carrying the message is an intermediate node, the message is forwarded to other met adjacent nodes except the adjacent node forwarding the message to the itself, wherein the social feature similarity of the other adjacent nodes and a target node is larger than the social feature similarity of the intermediate node and the target node. By the routing method, equipment and system for the delay tolerant network, the message is forwarded to the nodes similar to the target node step by step, the message is transmitted to the target node fast, and routing efficiency is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a routing method, device and system for a delay-tolerant network. Background technique [0002] In recent years, the development and application of wireless technology has become more and more rapid. It has become a trend that the number of mobile devices exceeds that of fixed hosts. A large number of mobile devices constitute a new application scenario of wireless networks, namely Delay Tolerant Network (Delay Tolerant Network, Abbreviated as DTN). As mobile communication devices such as smartphones and PADs become necessities in people's lives, DTN with personal mobile devices as nodes is more controlled by "people", and people are social, and everyone is on the Internet. Constantly moving and connecting according to their own preferences and needs, if two people have more similarities in society than other people, then the connection between them will be more f...
