Embodiment Construction

[0042] The specific implementations (examples) of the present invention will be described below in conjunction with the accompanying drawings in the specification, so that those skilled in the art can better understand the present invention.

[0043] Step 1. Construction of a binary tree based on video blocks: In the video server, any video can be divided into n video blocks, evaluate the popularity of each video block, and organize all video blocks with higher popularity into In a binary tree based on video blocks, each node in the binary tree structure derives a linked list structure that contains unpopular video blocks.

[0044] Step 2. Construction of node community: Evaluate the stability of the playback status of each network node, and organize network nodes with stable playback status and the same video block or network nodes with unstable playback status and the same video block into the network according to the evaluation results In the node community, each network node co...

Abstract

The invention discloses a clustering tree based video sharing method in a mobile Ad-Hoc network. The clustering tree based video sharing method in the mobile Ad-Hoc network comprises the steps of building a binary tree structure which is composed of high popularity by evaluating the popularity of video blocks; organizing network nodes, which plays the same video block steadily, to a network node community based on state stability evaluation results of video playing of the network nodes, wherein each network node community corresponds to video block nodes in a chain table based binary tree structure, and mapping between the network nodes and the chain table based binary tree structure is accordingly realized; and building logic connection among the network node communities, which is used for forwarding a video request message, based on connection among the video block nodes in the chain table based binary tree structure. The clustering tree based video sharing method in a mobile Ad-Hocnetwork has the beneficial effects of having relatively high searching performances, being capable of supporting rapid forwarding of the request message, accordingly and efficiently reducing video searching delay and increasing the searching efficiency of videos.

Description

Technical field [0001] The invention relates to the technical field of video search, in particular to a video sharing method based on a clustering tree under a mobile ad hoc network. Background technique [0002] A mobile ad hoc network is a collection of wireless devices that move randomly within a specific geographic area and can achieve autonomous maintenance and forwarding of routing information and data. In a mobile ad hoc network, each wireless device is not only a data sender and receiver, but also a data routing and forwarding node, and data forwarding and mobile management of wireless devices can be realized without a fixed base station. The mobile ad hoc network can be applied to disaster recovery systems and military, and has attracted many scholars to study it. Such as figure 1 As shown, because mobile video services enable users to quickly obtain rich visual content from the Internet through smart handheld devices, mobile video services have become the most popular ...
