IEEE 802.11 WLAN is preferred for IPTV in-home distribution, but the achievable throughput and coverage are still limited due to the high attenuation and interference in a household environment. Through our measurement study with a WDS-based multi-hop wireless testbed, we have found that it is possible for multi-hop wireless networks to increase the coverage and improve the video streaming performance at the same time. To analyze the throughput of IEEE 802.11 multi-hop wireless networks, we propose an extended two-dimensional Markov-chain model in this paper. Different from existing work, our model takes the retry limit and post-backoff stage into account to better capture the behavior of IEEE 802.11 MAC protocols in a non-ideal channel and with non-persistent traffic. The throughput analysis is validated by network simulation with extended lower and upper-layer simulation modules. The achievable throughput gives an upper bound of the video streaming performance, which is further validated by our H.264-based video streaming simulation with application-layer performance metrics. The results correspond to the observation we had on the multi-hop testbed. Further, this paper also provides some guidance on how to achieve the optimal balance for a given scenario, which is important when deploying video streaming services with end-to-end quality-of-service provisioning.
