Multihop D2D Communication to Minimize and Balance SAR in 5G

5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices. But this system causes high specific absorption rate (SAR). Hence, we introduce a novel technique.

In this paper, we propose an elegant method of band selection with appropriate data rate for multi-hop packet routing, to minimize and also to balance the transmission power and hence the associated EMF effect on us in terms of the Specific Absorption Rate (SAR). Theoretical analysis has been presented for linear networks that results an upper bound on the number of hops permitted for a given spectrum band.

Simulation results on random networks show that the proposed technique achieves a better improvement in terms of SAR, compared to the conventional direct communication via base station.
