“…The gain's influence on the relay system is shown in Figure 4. Equation 7helps us get a tight lower bound for an AF system instead of being an exact formula for the choice of relay gain in Equation (11). From the analysis of Section 3, we know the instantaneous SNR γ AF is dependent on the gain A.…”

“…In suburban environments, there are spare infrastructures and few vehicles, which is why cooperative relay technologies have been proposed recently as an efficient solution to cope with the many challenges in VANETs [8][9][10][11]. In vehicular networks, road-safety warnings, road-condition reports, and other safety messages are critical for ensuring road traffic safety.…”

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

“…Yet, vehicles featuring radio access equipment can also be useful for enhancing the performance of the mobile network itself; specifically, utilizing vehicles as relaying nodes between BSs and conventional UEs (e.g. smart-phones) has significant potential for coverage extension of mobile networks, especially in urban areas where vehicles are basically omnipresent [38]. Thus, equipping…”

Dependability is a measure of availability and reliability of systems/services. In the context of communication systems, dependability is governed by the coverage probability of the network under prescribed service requirements, by the latency of data transmissions as well as by the transmission error probability. Achieving dependable connectivity can be very challenging, especially within wireless mobile communications, where the transmission channel is often prone to severe fading and strong interference. Current generations of cellular mobile communication systems (4G and below) can mainly provide best effort services and are not well equipped to achieve a sufficiently high level of dependability as required by many novel applications, such as, road-safety relevant information exchange in vehicular communications, as well as, wireless remote operation of robots and drones. Standardization bodies have already recognized the market potential of such use-cases for mobile communications, and correspondingly efforts are ongoing to enhance the fifth generation of cellular systems (5G) towards ultra-reliable low-latency transmission. In this paper, we provide insights gained by our research work within the Christian Doppler Laboratory for Dependable Wireless Connectivity for the Society in Motion with respect to factors influencing the dependability of 5G mobile cellular systems, and we present our achievements over the past two years for enhancing the robustness, reliability and efficiency of dependable wireless communications.
