D2D communication with energy harvesting relays for disaster management

D2D Multi-hop Multi-path Communications in B5G Networks: A Survey on Models, Techniques, and Applications

“…During the routing path establishment process, the relay selection technique is deployed to find the set of successive forwarders who can relay the advertisement message successfully from the SU to the DU over the shortest path using geographical user information. In addition, the shortest path routing protocol can be simply done by selecting the set of relay nodes to form the path with minimum number of D2D hops [24], low symbol error rate and outage probability [29], max-min capacity [31], or with energy harvesting [36] and secrecy [42] added to enhance the system performance.…”

“…Further reactive caching techniques that are more efficient are required to study in the context of D2D MHMP communications.

And then, whenever a DU requests the content, D2D MHMP D2D communications are immediately established to serve the DU.…”

“…In particular, in [54,64], a relay EU acts as not only an information transfer (IT) node but also an energy harvesting node (energy harvested from the MBS in functional area) and an energy transfer node (to the next relay node in nonfunctional area). The process of EH and IT can be repeated over a path from the SU to the DU as studied in [36].…”

Energy Efficient Two-hop D2D Communications Underlay 5G Networks: A Stackelberg Game Approach

“…In this section, we study the main solutions of two-hop D2D communication in partial coverage scenarios, where devices located in non-covered areas can benefit from other UEs acting as extensions of active cells [9]. Meanwhile, the candidate relay may experience interference, require more energy resources, and calculation capabilities to route the additional traffic.…”

“…Many papers propose clustering approaches [8,9,10]. They group the covered mobile terminals in clusters then a cluster head is selected to relay the data to the out of coverage UE.…”
