… BS via a set of D2D relays. As the candidate UE relays work in duty cycle to save energy,
we derive a model to select a set of UE relays and perform opportunistic D2D communication …

… To select the IoT device-RRB-relay scheduling that provides a local minimum energy
consumption, we design a proper weight w(v) to each vertex v ∈ GJ-FL. For notation simplicity, we …

… • Two-hop Transmission [5]: In this scheme, only one relay is selected for data transmission
and the other relay is considered as a pure eavesdropper. Here, we select R1 as the helper …
