Voice multicast in low power low bandwidth mobile wireless networks

Qi Han | qhan@mines.edu

Using low-power wireless networks for emergency response has gained increasing attention over the years. In particular, almost ubiquitous wearable devices and smartphones have enabled the construction of critical ad hoc voice communication networks in many emergency situations such as survivors after an earthquake. In such scenarios, existing communication and power infrastructures are often destroyed, an ad hoc voice multicast system can help to deliver useful information from the emergency response center to survivors. Such a system bridge powerful smartphones and low power wireless nodes deployed on site. Because of the portability and low cost in comparison with current 802.11 platforms, these can be massively installed in buildings or mines and provide multi-hop voice communication capabilities in emergency scenarios. This project is to study the problem of multicasting voice streams from a source to multiple sinks over multi-hop low power wireless networks, i.e., voice stream multicast, in the presence of user mobility.
