Abstract

This paper presents a performance evaluation of a hybrid FEC/SR-ARQ (HARQ) analytical model. This model maps the impact of finite link layer (LL) buffer size, retransmissions and code rate on HARQ performance. The analytical model is validated by extensive ns-2 simulations. An accurate HARQ model will allow better prediction of performance through not only wireless link efficiency but also higher layer (particularly transport layer) protocols. This can be translated to improved utilisation of network resources and therefore greater end-user and network provider satisfaction.
