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.
