The focus of the paper is to propose an analytical model for the operation of TCP over multi-copy SR ARQ systems on wireless fading channels. A major contribution is a competent analytical approach which promotes better understanding of the behavior of the wireless link layer protocol with correlated errors and the interaction between end-to-end TCP and local link layer protocol. The analytical TCP model suggested by J. Padhye et al. (see IEEE/ACM Trans. Networking, vol.8, p.133-45, 2000) is also reinvestigated in the wireless portion of the network. The accuracy of the analytical model is validated by simulation.
