摘要
为了提高无线传屏的链路稳定性和数据传输可靠性,增强无线传屏的视觉效果,研究建立了一种感知环境下多媒体数据共享的节点协作感知模式,确定了基于协作上下文感知的无线传屏模型及其工作方法,并针对传屏中出现的数据不一致性问题,提出了一种面向突发错误的数据不一致性消除算法.该算法通过反馈和加窗处理,提升了算法的抗突发错误能力,并提高了无线传屏中传屏数据不一致性消除的正确率,使无线传屏数据可以在复杂环境下获得可靠的传输.仿真结果表明,在数据包含突发错误时该算法的正确率优于其他同类算法.
In order to improve the stability and reliability of the wireless screen transmission,and enhance the visual effect,a collaborative context-aware pattern of multimedia data sharing was presented,and a model of wireless screen transmission based on collaborative context-aware technology was established as well.To overcome the problem of data inconsistency in wireless screen transmission,a data inconsistency resolution algorithm for the burst error was proposed.By using feedback and windowing processing,the accuracy of algorithm is improved,and hence the stability and reliability of the transmission can be guaranteed in complicated environment.Simulation results show that the new algorithm outperforms its counterparts in accuracy when burst errors occur.
