Here, we list all possible transmission sequences.
In the first case, Node 2 occupies the second slot. Since there is no preceding node to recover the scheduling result, the reliability factor is 2.
In the second case, Node 2 transmits after Node 1, but the link between Nodes 1 and 2 is highly unreliable. The reliability factor remains 2.
In the third case, Node 2 transmits after Node 3. The link between Nodes 1 and 3 is reliable, so the reliability factor increases to 3.
Sequences 4 and 6 are examples of reliable transmission sequences. |
