In this study, we developed network and throughput formulation models and proposed new method of the routing protocol algorithm with a here cross-layer scheme based on signal-to-noise ratio (SNR).This method is an enhancement of routing protocol ad hoc on-demand distance vector (AODV).This proposed scheme uses selective route based on the SNR threshold in the reverse route mechanism.
We developed AODV SNR-selective route (AODV SNR-SR) for a mechanism better than AODV SNR, that is, the routing protocol that used average or sum of path SNR, and also better than AODV which is soderhamn ottoman cover hop-count-based.We also used selective reverse route based on SNR mechanism, replacing the earlier method to avoid routing overhead.The simulation results show that AODV SNR-SR outperforms AODV SNR and AODV in terms of throughput, end-to-end delay, and routing overhead.
This proposed method is expected to support Device-to-Device (D2D) communications that are concerned with the quality of the channel awareness in the development of the future Fifth Generation (5G).
