IEEE 802.11 WLAN is most well-liked for IPTV in-home distribution, however the achievable throughput and coverage are still limited because of the high attenuation and interference during a household environment. Through our measurement study with a WDS-primarily based multi-hop wireless check bed, we have found that it's potential for multi-hop wireless networks to extend the coverage and improve the video streaming performance at the identical time. To analyze the throughput of IEEE 802.11 multi hop wireless networks, we tend to propose an extended two-dimensional Markov-chain model in this paper. The throughput analysis is validated by network simulation with extended lower and higher-layer simulation modules. The achievable throughput gives an higher certain of the video streaming performance, which is further validated by our H.264-primarily based video streaming simulation with application-layer performance metrics. The results correspond to the observation we have a tendency to had on the multi-hop check bed. Further, this paper conjointly provides some steering on how to realize the optimal balance for a given scenario, that is vital when deploying video streaming services with end-to-end quality-of-service provisioning.
