A practical approach to multicasting in Bluetooth piconets

This work studies a special multicasting problem in Bluetooth networks supporting point-to-point connections and piconets. The reason for the topic choice relies in the fact that Bluetooth, a de-facto proximity communication technique widely available in smart phones today, supports piconets, but sending content to more than 7 nodes is cumbersome. It turns out that by using a non-standard approach, that of parallel piconets of two nodes each, we can obtain a more efficient multicasting than through the legacy multicasting approach
