Abstract :
We consider scheduling schemes which exploit the random variability in wireless channels to maximize wireless throughput. We survey ten of such opportunistic scheduling policies, namely, PFS, OCASD, TAOS-1, I-OCASD, CASTI, EXP, M-LWDF, FIFO, RR and MaxC/I and compare them in terms of system throughput, fairness (user isolation) and the distributions of user starvation periods (packet delays) in a time-slotted wireless network like CDMA/HDR using adaptive modulation and coding (AMC). The results aids in determining the suitability of any of the ten policies in a wireless network depending on which metric is considered critical.
