Embodiment
[0065] Such as Figure 1-7 , a data transmission scheduling method based on unequal relay sets in a wireless sensor network. In a wireless sensor network, each node independently adopts the work / sleep periodic rotation work mode, and the node can only transmit data when it is in the working state. transmission; each node v i Select multiple relay nodes to form a relay node set;
[0066] node v i When a data packet needs to be transmitted, first initiate data transmission to the relay node that wakes up first in the relay node set, if unsuccessful, wait for the next awakened node in the relay node to send data until the data is successfully sent to the relay If the node, or every relay node in the relay node set fails to transmit, the transmission of the data packet is abandoned.
[0067] Determine the node v i The method of the number of relay nodes is as follows:
[0068] Step 1: Set node v i The initial number of relay nodes is δ; if it is set to 2, 3 or 5, etc., it is...
