摘要
为了提高数字多媒体网络的通信效率,需要对数字多媒体网络通信延迟消除方法进行研究。当前通信延迟消除方法不能准确的对网络通信状态进行预测,通信延迟消除效果较差。提出一种数字多媒体网络通信延迟快速消除方法,基于受控自回归积分滑动平均模型结合通信优化目标函数和丢番图方程将网络通信控制问题转化为二次规划问题,得到通信控制预测向量。根据数字多媒体网络通信预测控制向量,采用平衡负载算法划分数字多媒体网络中的通信任务,将通信任务分为高质量通信任务和低质量通信任务,通过Min-Min算法对网络通信任务进行控制,消除数字多媒体网络中存在的通信延迟。仿真结果表明,所提方法可以准确的对网络通信状态进行预测,有效地消除数字多媒体网络中存在的通信延迟。
In order to improve the communication efficiency of digital multimedia network,this paper presents a method to quickly eliminate the communication delay in digital multimedia network. Based on the controlled auto-regressive integrated moving average,the communication optimization objective function was combined with Diophantine equation to transform the network communication control problem into the quadratic programming problem,and then the communication control predictive vector was obtained. Based on the predictive control vector of digital multimedia network communication,the balancing load algorithm was used to divide the communication tasks in the digital multimedia network,including high-quality communication task and low-quality communication task. Finally,the MinMin algorithm was used to control the network communication task and eliminate communication delay in digital multimedia network. Simulation results show that the proposed method can accurately predict the state of network communication and effectively eliminate the communication delay in digital multimedia network.
