| Abstract: | ROHC is a header compression protocol proposed by IETF,which can be used to save wireless bandwidth.The basic ROHC principle and the transition logic of ROHC mode and state are briefly introduced.The W-LSB compress and decompress algorithm is deeply studied and the main functions in this algorithm is realized.The ROHC is modeled with SDL language.Last the performance analysis and the prospect of ROHC protocol are given. |
