Consider a two-hop lossy low-power IoT network with nodes N1,N2and N3 where each hop has a success probability of 0.8 for datapackets and 1.0 for acknowledgements. Assume N1 wants to send adata packet to N3. N3 is out of range from N1, so N2 needs toforward the packets (in both directions). Assume link-layerretransmissions are used. As network operator, you can set themaximum number of link layer retransmissions as a global parameter,i.e., valid for all links.
Which is the lowest number you can select for the maximumnumber of link layer retransmissions so that theprobability that the probabilityfor success when sending a packet
