Clock synchronization in shared media networks is particularly challenging because the operating conditions are dynamic and the resources limited. This paper presents TurboSync, an accurate and bandwidth efficient synchronization scheme. Unlike traditional solutions that synchronize pairs of nodes, TurboSync, is able to synchronize entire node clusters. TurboSync relies on principal component analysis with missing data. Packets are broadcasted on the medium and their capture times at each node side are used to compute the clock conversion parameters.
