With the proliferation of wireless network, one area will become popular – real-time multimedia applications. The development of header compression technique will also bring improvement to the wireless access.

In this article, the authors described how a robust header compression (RoHC) can be used to reduce the overhead of IP-based traffic. And Voice over IP (VoIP) may replace the voice circuits in the future wirless network applications (IEEE 802.11 technology).

A simulation study of the RoHC’s U-mode performance when applied to VoIP in an 802.11 link is described.
