For the problem of cross-domain node sleep and network congestion caused by load transfer, this paper propose an energy-efficient policy based on collaborative sleep mechanism between cross-domain node with load transfer in WOBAN. By analyzing the current load of the Optical Network Unit (ONU) and the collaboration between ONU and wireless router, this paper applies maximum matching theory to determine sleep node and the destination of load transfer so as to reduce energy consumption on the basis of ensuring the connectivity and low latency of network. Simulation results show that the proposed algorithm can reduce the energy consumption of entire network without having a significant impact on the network packet delay.
