Abstract: In order to satisfy the requirement of energy constrained in Wireless Sensor Network(WSN), an energy-efficient multihop broadcast synchronization algorithm based on double broadcast domain is proposed. The algorithm is based on Receiver-receiver Synchronization(RRS). Node synchronization range is expanded to two broadcast domains by peer-to-peer broadcasting message in a pair of synchronized nodes which need to broadcast message one more time. A hierarchical structure with two root nodes is built, and the algorithm is extended to the network-wide. OMNeT++ simulation results show that the proposed algorithm requires much less timing messages for network-wide synchronization than MBS algorithm.
