A reliable TCP-aware link layer retransmission for wireless networks

We develop a new TCP-aware link layer retransmission scheme that can offer almost full reliable transmission over wireless channels and efficiently avoid the adverse interaction of different layer protocols. We introduce a time-stamp in our scheme to offer reliable delivery for out-of-order segments and use explicit retransmission notification (ERN) to avoid false window deflating and multiple retransmission of TCP source. By simulation, we conclude that our proposal can greatly improve TCP performance over wireless networks
