- Abstract
- A large data transmission method in a sensor network based on a media access control (MAC) is provided. The method includes dividing data to be transferred into a plurality of data segments; generating a plurality of media access control (MAC) segmented data frames by including in each data segment an indication that the data is generated by segmentation and assigning a sequence number to the data segment; transmitting the generated MAC segmented data frames sequentially; receiving a MAC reception failure frame indicating reception failure for a predetermined period of time from a receiving sensor node after completing the transmitting of all the MAC segmented data frames; and retransmitting the MAC segmented data frames which correspond to at least one sequence number included in the received MAC reception failure frame. Accordingly, large data transmission times can be reduced in a MAC for a sensor network.
