Fuzzy logic congestion control for broadband wireless IPTV

It is demonstrated that interval type-2 fuzzy logic control (IT2 FLC) is more robust than traditional fuzzy logic congestion control of video streaming. An IT2 FLC is compared to the well-known TFRC and TEAR congestion controllers for internet multimedia streaming. On an all-IP network with broadband wireless access, delivered video quality is improved with the IT2 FLC by about 1 dB for each client, once the offered traffic (up to 50 video streams) exceeds the capacity available to video over the wireless link.
