The transmission control protocol (TCP) is a large extendedtransport protocol, mainly used in fixed networks. It works well inthose networks in which the main cause of packet loss is congestion.Some mechanisms included in the TCP optimise their use in this kind ofnetworks. Today, Internet users need access it over wireless links inorder to get this service anywhere they are. However, the TCP does notwork well in wireless environments where losses are due to high biterror rates (BER). We evaluate the end-to-end throughput of a TCPconnection with a wireless link. First, we demonstrate the impact ofhigh BER in the TCP performance. Then, we optimise the throughput of theTCP connection choosing the best MTU (maximum segment size) in eachcase, and evaluate other aspects of interests
