Abstract. Wireless channels have a high channel bit error rate and lim-
ited bandwidth. The high bit error rate degrades the quality of multi-
media transmission, and also increases the buffer size requirement at the
client. In this paper, we propose a novel selective retransmission scheme
for multimedia transmission over wireless ATM networks using the ABR
service. Our objective is to develop a simple cost effective scheme which
offers quality of service for MPEG compressed video transmitted over a
noisy wireless channel. We have developed an analytical model to deter-
