Relay technology application becomes prevalent nowadays, as it can effectively extend\nthe communication distance, especially for vehicular networks with a limited communication range.\nCombined with vehicular cloud (VC), transmission efficiency can be improved by offloading partial\ndata. Hence, designing a vehicle relay algorithm and implementation embedded vehicle device is\ncritical. In this paper, VC is considered to deal with the complexity computation in our proposed\nsystem model. Without a loss of generality, an end-to-end vehicle communication with one assisted\nvehicle is analyzed firstly on a transmission link based on VC. Here, the signal-to-noise ratio\n(SNR) on the receiving end and link outage probability is obtained to enhance the link reliability.\nThe VC computing helps us further simplify computational complexity. Subsequently, an embedded\nvehicle-enabled device is designed to achieve the optimal path relay selection in realistic vehicular\nenvironments. In the functional device framework, we display an optimal path relay selection\nalgorithm according to the link quality. Finally, the performance of the transmission link on the\noutage probability related with SNR is verified in the simulation results. Meanwhile, the effect of the\nrelay gain is also analyzed. The application of a vehicle-enabled embedded device could improve the\nperformance of vehicular networks.
