Adaptive Voice Streaming over Low-power Wireless NetworksSpeaker: Qi Han – Golden, CO, United States
Topic(s): Networks and Communications
AbstractLow power wireless networks have become increasingly popular for mission-critical applications such as security surveillance and disaster response. In particular, emerging low power wireless audio platforms provide an economical solution for ad hoc voice communication in emergency scenarios. In this talk, I will describe a system we designed and developed for voice streaming multicast over multi-hop low power wireless networks. The system is specifically designed to deliver robust voice quality for multiple sinks in dynamic environments. Our system has been implemented on a low-power hardware platform and extensively evaluated through experiments on a testbed of 18 nodes. I will also discuss how node mobility impact the voice quality in such an environment and our approaches to tackle the challenges.
