In face of the rapidly increasing cellular traffic, 5G will employ offloading techniques to relieve the cellular infrastructure. The idea is to carry the traffic locally by User-Equipment (UE) relays or by other coexisting radio access technologies such as WiFi, Bluetooth, etc. To this end, in this paper, we propose an offloading scheme using multi-hop LTE-D2D communications and assisted by the operator. LTE-D2D UEs cooperate to carry intra-cell unicast/multicast traffic from sources to

To increase the lifetime of the offloading system and to reduce the impact of the relaying process on the battery-limited UEs, we propose our energy-aware approach, named JRRA-EE, to solve jointly the routing and the OFDMA resource block allocation. We formulate our problem as a 0-1 Integer Linear Programming (ILP) model which is elaborated to take into consideration the realistic LTE-D2D capabilities and constraints. To gauge the effectiveness of our proposal, we implement the whole 3GPP LTE-D2D protocol stack in the NS-3 network simulator to simulate our approach. Based on extensive simulations, the obtained performances of JRRA-EE are better compared to other one-sided optimal strategies, including an energy non-aware variant, in terms of i) the network lifetime, ii) the packet loss and iii) the service interruption rate.
