Wireless TCP proposals with proxy servers in the GPRS network

The General Packet Radio Service (GPRS) system will offer to the users an easy access to Internet applications which work with the TCP protocol. We analyse by means of simulations the performance in the GPRS network of the following wireless TCP proposals that use a proxy server: the Snoop protocol and the Split mechanism. We also describe the impact of the GPRS LLC layer in acknowledged mode in the TCP end-to-end throughput. Unlike previous research we consider two scenarios for the GPRS radio interface: one with several users present in the system, and the other with only one user in it.
