Embodiment Construction

[0054] The invention provides a novel delay-tolerant mobile social network routing method based on a node label set, which uses the node's own label set to perform path-finding and forwarding of the delay-tolerant mobile social network route.

[0055] First deploy as figure 1 As shown in the network environment, the network mainly includes mobile nodes with communication functions (such as smart phones, PDAs, etc.) and label management systems. The mobile node can access the label management system and install the corresponding label application program. The label management system includes upper application and standard label library.

[0056] The method mainly includes (1) establishment of a standard tag library; (2) acquisition and management of the node's own tag set; (3) pathfinding and forwarding based on the tag set. figure 2 shown. These three parts are described in detail below:

[0057] (1) Establish a standard tag library

[0058] The label management system is...

Abstract

Along with the development of the research of delay tolerant network, delay tolerant mobile social network becomes a hot topic in the research. The existing routing suitable for the network is mostly used for dividing nodes into different communities according to the social relations of the nodes by analyzing the social relations among the nodes, and way-finding forwarding is carried out by means of the relations among the nodes. However, because of the influence of the owner, namely people, the social relations among the nodes are subtle and complex and hard to analyze, and the spending of node calculation and maintenance is relatively large. By means of the conception of the label, each node just maintains the label set of oneself according to own situation without knowing the information of other nodes, and way-finding forwarding is carried out by means of the label set of the nodes; way-finding forwarding strategies suitable for corresponding conditions are respectively proposed according to the difference of target node knowledge degree; and the method is novel, simple and high-efficient.

Description

technical field [0001] The present invention proposes a tag-based routing method for Delay Tolerant Mobile Social Networks (DTSN for short), which is mainly used to solve the problem of how to obtain the social relationship between nodes in the delay-tolerant mobile social network. The problem of realizing simple and efficient routing belongs to the technical field of computer wireless communication. Background technique [0002] The traditional Internet uses the TCP / IP (Transfer Control Protocol / Internet Protocol) protocol family as its architecture, which requires a stable end-to-end network connection. However, some networks built in extreme environments or lacking communication infrastructure cannot satisfy the end-to-end continuous and stable connection of the network, making the traditional network architecture no longer applicable. Such as interstellar network, rural network, field expedition network, etc. In order to realize network communication in these environme...
