Abstract

The invention relates to a mobile delay tolerant network rapid message notification method based on shortcut and a mobile delay tolerant network rapid message notification device based on shortcut. The method comprises steps that: a detection message is sent by a message source to a mobile delay tolerant network; after the detection message is received by any node in the mobile delay tolerant network, the message source is updated by a detection node to time delay information of the detection node, and the detection message is stored in a forwarding queue; when the detection node meets a meeting node, whether shortcut is established between the detection node and other nodes is determined; whether the detection node and the meeting node meet shortcut establishment requirements is determined; when the detection node receives a notification message, if the detection node is an end node, the notification message is forwarded to another end node through shortcut, if the detection node is not an end node, the notification message is stored by the detection node in the forwarding queue, and the notification message is forwarded to other nodes when the detection node meets other nodes. According to the method and the device, rapid forwarding of the notification message is realized through establishing the safe shortcut.

Description

technical field

[0001] The invention relates to the technical field of mobile delay-tolerant networks, in particular to a shortcut-based mobile delay-tolerant network fast message notification method and device. Background technique

[0002] Mobile delay tolerant network is a kind of wireless network whose communication link has intermittent characteristics, and the whole network cannot satisfy full connectivity. In order to solve the problem of network topology disconnection, the mobile delay-tolerant network introduces the "store-carry-forward" communication method, and uses the inter-node communication opportunities brought by the movement of nodes with storage capabilities for data transmission. The mobile delay-tolerant network realizes the data transmission of the disconnected network through a certain delay cost, and improves the scalability and availability of the network.

[0003] Mobile delay-tolerant network is an important type of mobile network, relying on the ...
