| Abstract: | The technology of header compression,its related work and the principle of ROHC(RObust Header Compression) protocol have been briefly summarized.The coding algorithm of W-LSB(Windows-based Least Significant Bits) has been deeply analyzed.The optimized values of some key parameters in ROHC are given through simulation,both the compression rate and robustness of ROHC are considered by these optimized values at the same time,and thus the performance of ROHC is optimized. |
