The Eifel TCP extension over GPRS RLC: effects of long radio blackouts
Tayeb Diab, Philippe Martins, Philippe Godlewski, Nicolas Puech · 2003
We present a GPRS simulation platform developed as a new module of the UCB/LBNL/VINT network simulator (ns-2). This platform provides the functionalities of the RLC/MAC layer of GPRS with the support of several mobile stations in a single cell. It enables us to evaluate end to end performance of TCP connections over GPRS. Simulations show that long delays caused by long radio blackouts could cause spurious retransmissions of TCP segments. We investigate the performance of the new Eifel TCP extension with respect to this problem.
