Abstract

In this paper, we consider the problem of transmitting compressed video over wirless LAN under transmission power constraints, where retransmission is adopted as the error control scheme. For different retry limits, transmitter energy per bit is adjusted to keep a constant video quality at the receiver, which costs different transmission power. We propose an algorithm to minimize transmission power by carefully choosing the maximum number of retransmission times and transmission energy level based on the quality and delay requirement. We also examine the effect of distance on the choice of the optimal points.
