Data Transmission Method and Device |
摘要 |
A data transmission method and device are provided. The data transmission method includes determining, by a network node, that a destination sensor node of to-be-transmitted data is in an inactive period; sending, by the network node, a wake-up message to the destination sensor node, where the wake-up message is used to trigger the destination sensor node to enter a woken-up state from a dormant state of the inactive period; receiving, by the network node, a response message that is from the destination sensor node and for the wake-up message; and performing, by the network node, data transmission with the destination sensor node according to the response message. According to the embodiments of the present invention, a data transmission delay is reduced, and data transmission synchronization is ensured. |

1. A data transmission method, comprising:
determining, by a network node, that a destination sensor node of to-be-transmitted data is in an inactive period; sending, by the network node, a wake-up message to the destination sensor node, wherein the wake-up message is used to trigger the destination sensor node to enter a woken-up state from a dormant state of the inactive period; receiving, by the network node, a response message that is from the destination sensor node and for the wake-up message; and performing, by the network node, data transmission with the destination sensor node according to the response message. |
