Adaptive robust TCP/IP header compression algorithm for 3G wireless networks

The future telecommunication systems will be surely characterized by the convergence of mobile technologies and Internet protocols, achieved through a network platform totally based on TCP/IP protocols ("all-IP network").In such a system, both wired and wireless parts are built on a common network platform based on TCP/IP protocol. However, TCP/IP protocol headers overheads are large and need to be compressed to save radio channel bandwidth which is the most expensive and scarce resource of the whole wireless system, especially for some services whose payload size is small. In this paper, a new adaptive robust TCP/IP header compression algorithm for 3G wireless networks is proposed and analyzed. The aim of this algorithm is to adjust the dimension of variable sliding window (VSW) in W-LSB encoding wiith the accurate estimation o wireless channel state to achieve the good balance of compression ratio and error-resistant robustness for the adaptive use in wireless link. We present simulation results that demonstrate the effectiveness of this adaptive algorithm over wireless link.
