Continuous Reference Broadcast Synchronization with Packet Loss Tolerance

초록

Among synchronization protocols applied in wireless sensor network, reference broadcast synchronization (RBS) is one prominent protocol achieving very high accuracy of synchronization given that the broadcasting medium is available. However, that the protocol lacks packet loss tolerance brings about degraded performance in severe conditions of wireless channel. Also, the instantaneous synchronization used in this protocol results in time discontinuity, which might cause serious faults in the distributed system. In this study, we propose a packet loss tolerance and continuous synchronization mechanism for RBS. Then we verified the result through simulations.
