With the aim of resolving the problem that sensors use asynchronous sleep-wake scheduling to increase the communication delay,this paper proposes a regulating duty-cycle mechanism based on the excellence of parallel of Dual-Radio.This mechanism makes the wake-up time of node earlier by regulating the duty-cycle of nodes dynamically,and predicts the conflict on the data transmission to reduce the interference of conflict.Simulation experimental results and theoretical analysis show that solution uses less energy and reduces the communication delay.
