“…DSA has been applied to vehicular networks e.g. using the TV white space band [17] or exploiting historical spectrum sensing data [18]. In heterogeneous networking, all users are considered primary users and they are all equipped with multiple RATs that are assigned specific channels and spectrum bands.…”

Connected and automated vehicles will enable advanced traffic safety and efficiency applications thanks to the dynamic exchange of information between vehicles, and between vehicles and infrastructure nodes. Connected vehicles can utilize IEEE 802.11p for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. However, a widespread deployment of connected vehicles and the introduction of connected automated driving applications will notably increase the bandwidth and scalability requirements of vehicular networks. This paper proposes to address these challenges through the adoption of heterogeneous V2V communications in multi-link and multi-RAT vehicular networks. In particular, the paper proposes the first distributed (and decentralized) context-aware heterogeneous V2V communications algorithm that is technology and application agnostic, and that allows each vehicle to autonomously and dynamically select its communications technology taking into account its application requirements and the communication context conditions. This study demonstrates the potential of heterogeneous V2V communications, and the capability of the proposed algorithm to satisfy the vehicles' application requirements while approaching the estimated upper bound network capacity.

“…The primary signal is modeled as a Gaussian process, which is a prevalent assumption in the literature on spectrum sensing. In [4][5][6][7] [13], it is shown that in the case of DVB-T2 signals, this assumption is well motivated. The problem of spectrum sensing is to decide whether there is a signal transmitted or not.…”

“…IEEE 802.22 is a standard for wireless regional area network (WRAN) using white spaces in the television (TV) frequency spectrum, where spectrum sensing is included as a mandatory feature [7]. The standard is intended for cognitive operation in the digital TV bands, among others.…”

“…The standard is intended for cognitive operation in the digital TV bands, among others. As a result of the standard, a SU must be able to detect a PU digital video broadcasting (DVB-T) signal with probability of detection (Pd) at least 90% and probability of false alarm (Pf) no more than 10% at -22.2 dB signal-noise-ratio (SNR) [7]. CR operations in the DVB-T spectrum have also been deliberated in other research literature [8][9][10].…”

“…In the meanwhile, plenty of TV White Spaces (TVWS) bands, which have desirable long-distance propagation char-acteristics [6], [24], [25], can be used as a feasible supplement to the limited DSRC bandwidth [3], [6], [24]- [27], and related standards have been put forwarded by relevant organizations such as U.S. Federal Communications Commission (FCC) [28]. Therefore, to solve the related wireless spectrum problems, in this paper we will investigate vehicular computation offloading using TVWS band for wireless data transmission.…”
