    Enhancements to ECRTP with Applications to Robust Header 
                   Compression for Wireless

Abstract

Enhanced Compressed RTP (ECRTP) and Robust Header Compression
(ROHC) are IP header compression schemes that have been 
proposed for use in wireless applications, primarily for
voice and audio applications.  While ROHC offers a high
degree of compression and is robust, it is also computationally
expensive. On the other hand, ECRTP does not achieve as high
a compression, while being less expensive computationally. 
Our proposal, E2CRTP, is an enhanced version of ECRTP that
offers a middleground between the ROHC and ECRTP, providing
robustness, compression efficiency, and moderate computational
complexity.
