ABSTRACT:
Due to bandwidth constraints on the wireless link in an IP network, it is useful to compress the headers so as to maximize the utilization of the link. There exists Header Compression algorithms that make use of the similarity in consecutive headers in a packet flow to compress these headers. In this document, a novel header compression scheme was introduced that makes use of the similarity in consecutive flows from or to a given mobile terminal to compress these headers. Using information theory, the optimal gain to be expected from the use of such a scheme was analyzed. A model was defined for the distribution of the connections of a single user over the address space. The compression scheme was evaluated with respect to this model and to actual internet data traces. The scheme is complementary and the benefits are additional to the traditional approach to header compression. However, the scheme outperforms current schemes with respect to actual internet traces.
