Abstract :
We analyze the performance of two selective repeat automatic repeat request (SR-ARQ) protocols, which exploit the differences in bit protection levels of M-ary PSK symbols (with Gray code mapping), to support multimedia multicasting in wireless networks. Our simulation results reveal that the throughput performance of the proposed SR-ARQ schemes are significantly better than the traditional SR-ARQ protocol in a myriad of fading environments. The relative throughput improvement is generally greater for channels that experience severe deep fades and fast fading. However, the power efficiency improvement appears to be relatively insensitive to both the fade distribution and node mobility.
