文章从提高无线网络数据传输的综合性能出发,引入帧分段机制。理论分析证明了该机制能够降低网络传输的误码率、提高帧传输效率,进而对机制作了改进:根据原始包长自适应分段,并考虑不同业务性能参量及不同站点的需求,分别设计不同分段机制。最后,得到了适用于固定站点和移动站点的帧分段方案,并通过OPNET仿真验证了研究结果的正确性。 The article starts from improving the overall performance of wireless network data transmission and introduces the frame segmentation mechanism. The theoretical analysis proves that this mechanism can reduce the bit error rate of the network transmission and improve the frame transmission efficiency, and then improve the mechanism: According to the original packet length adaptive segmentation, and considering the different business performance parameters and the needs of different sites, respectively, design Different segmentation mechanism. Finally, a frame segmentation scheme for fixed and mobile stations is obtained. The correctness of the research results is verified by OPNET simulation.
