A Dynamic Rate Control Scheme for Video Streaming on Inter-Building Wireless Networks

2.4 GHz radio band is commonly used by many systems and appliances such as IEEE802.11b, Bluetooth, RFID, and even microwave ovens. Radio interference among these is often observed. Therefore, in 2.4 GHz inter-building wireless networks, available throughput temporally changes, which could yield serious packet error and/or packet loss. In this paper, we propose a new dynamic source rate control scheme by using ICMP (Internet Control Message Protocol) echo success rate, RTT (Round Trip Time) and scalable-coded-video source to reduce packet error and packet loss for video streaming applications. We apply the scheme to the inter-building wireless system installed between Kogakuin University and Waseda University in Tokyo. It is shown that the proposed scheme significantly reduces PER and increases effective throughput.
