* Question
| What are the routing algorithms for filtering injection nodes based on utility functions? |
* Answer
| That is, if the node encountered has a higher utility value than the carrier, the message is passed to the encountering node.The utility function is further divided into purpose-related and purpose-independent.The LSF (1ast seen first spraying) algorithm is related to the purpose, and the algorithm is based on the time of the last encounter with the destination node. |
