| 摘 要： | 提出了一种基于模糊免疫PID的多媒体流自调整算法(MFIPID)，实现对多媒体流的在线自调节和多媒体流资源有效管理。分析多媒体流自适应节模型，实现IP网络可用带宽的预估计，采用全论域范围内带有自调整因子的模糊规则自调整方法进行免疫抑制量的模糊非线性逼近，并与免疫反馈机理相结合，多媒体流传输过程中自适应整定PID参数以改进传统PID算法。仿真验证了MFIPID算法的有效性。

| Abstract: | A multimedia streams self-regulating algorithm based on fuzzy immune PID is proposed to attain the goal of on-line self-regulating of multimedia streams and effective resource management. Model of adaptive session is analyzed, and available bandwidth' future estimation is achieved. The fuzzy nonlinear approximation of immune' suppresser is fulfilled by fuzzy rules' self-tuning with self-tuning factor in full domain. Then, in order to improve the traditional PID algorithm fuzzy nonlinear approximation is combined with immune feedback mechanism to adjust PID factors during the course of multimedia transmission. Simulation validates the theoretical results of MFIPID. |
