Function declaration
Relay mode function
| Features | functional description |
| Relay forwarding | After the terminal is configured as a relay node, it should relay the communication information of the sub node according to the configuration information on the basis of retaining the original
communication capability |
| Data caching | Data caching is set up at the relay node to ensure that data can be transmitted in subsequent communications when a node is
temporarily disconnected. |
| Packet acknowledgment | Each relay node sends a confirmation signal after receiving the data packet to ensure that the source node knows that the data has been
successfully transmitted. |
| Automatic retransmission | In case of data packet transmission failure, automatic retransmission mechanism can be set to ensure that data can be effectively
transmitted |
| Signal strength
monitoring |
Nodes can regularly monitor the signal strength of surrounding nodes to dynamically adjust the selection of relay nodes and
optimize the communication link |
| Packet loss
handling |
Monitor and process packet loss and ensure data integrity through
retransmission or other mechanisms |
Terminal mode function
| Features | functional description |
| Control commands are
issued |
The control command can also be issued to the target node through multi-level jump, so as to ensure the reliable transmission
of the command |
| Data acquisition and
encapsulation |
Data is collected from sensors or devices and encapsulated into packets |
| Data segmentation
and assembly |
Divide the big data into small segments to facilitate transmission through multiple levels of links, and then reassemble them at the
target node |
| Data compression
and optimization |
In uplink communication, data can be compressed and optimized to reduce the load of data transmission |
| Packet
sequence number |
Assign a sequence number to each data packet to ensure the order and integrity of the data |
| Packet acknowledgment | After receiving the data packet, the target node sends a
confirmation signal to the source node to ensure the status of data transmission |
| Data caching and retransmission | In case of transmission failure, the relay node or the target node can buffer the data and perform automatic retransmission |
| Priority
management |
For different types of data, priority can be set to ensure that critical data is transmitted first |
