Abstract :
We propose and demonstrate a method for improving capacity for real-time interactive communications over multi-hop wireless networks using WiFi wireless devices. The proposed method uses aggregation of packets at access points designed to avoid bottlenecks in relay traffic and maintain low end-to-end latency. We present experimental results which demonstrate that a relay node can support seven concurrent voice-over-IP (VoIP) sessions using a single 802.11 channel.
