TCP performance degrades when end-to-end connections extend over wireless links which are characterized by high bit error rate and intermittent connectivity. Such degradation is mainly accounted for TCP's unnecessary congestion control actions while attempting TCP loss recovery. Several independent link loss recovery approaches are proposed by researchers to reduce number of losses visible at TCP. In this paper, the authors first presented a survey of loss mitigation techniques at wireless link layer. Secondly performance evaluation for TCP through type 0 automatic retransmission request mechanism in erroneous wireless LAN is presented.
