Performance analysis of a new header compression scheme for TCP streams in IP based wireless networks

In this paper, a new header compression scheme for TCP streams, as a specific header compression profile within the IETF ROHC platform, is proposed and analyzed through simulations by the Network Simulator. The proposed scheme is based on the distinct management of DATA and ACK streams associated to the TCP connection and it exploits a robust header encoding technique (W-LSB) for reducing the effect of error propagation. The achieved results, in terms of throughput, overhead and goodput, reported as a function of bandwidth and BER and compared with the results obtained without compression, allow its to evaluate the performance of the proposed compression scheme in a realistic and dynamic environment.
