An analytical model for the ROHC RTP profile

In this paper, we propose an analytical model for the RTP profile of robust header compression (ROHC) [C. Bormann et al., July 2001]. The model assumes that the RTP compressor and decompressor work in the unidirectional mode (U-Mode). It includes the features such as W-LSB encoding scheme, state-transition, compression slow-start and periodic context refreshment etc. It has been validated with NS-2 [NS-2 network simulator]. The model explains clearly how the robustness is enhanced by the W-LSB encoding scheme. It can also be used to analyze the performance of the header compression in the different wireless network.
