摘要

各类移动多媒体智能终端的普及使得设备间的自组织机会通信成为国际研究热点，而移动节点间的机会通信方式已无法满足日益增长的多媒体传输需求.面向机会组网与视频内容传输问题，基于机会网络实际通信能力计算，提出了一种视频分块大小最优化计算方法，使机会网络通信能力得到最大化利用；提出了一种能够实现渐进式接收视频分块的路由调度算法，建立分块紧缺度模型，引导分块在目标节点趋于均匀分布.实验结果表明，该方法能在恶劣通信环境下实现高效的视频数据预览与传输，可为相关视频内容的无线移动传输提供支持.

Abstract

Ad hoc opportunistic communication has become a hotspot with the popularity of various mobile multimedia intelligent terminals. However

the opportunistic communication style among mobile nodes cannot satisfy the growing of multimedia transmission. Aiming to the issues of opportunistic networking and video content transmission

based on the opportunistic network communication capability calculation

we proposed a method of calculating the optimal size of video fragment. The method could maximize the use of network communication capabilities. After that

a video routing and scheduling algorithm is proposed to receive video fragments progressively

and to create fragment priority model which results to uniform fragments distribution at destination node. The experimental results show that the proposed methods can make efficient video content preview and transmission in challenging communication environment

and can support the related video content transmission in wireless mobile environment.
