In this paper, we investigate the two-hop full-duplex (FD) relay channel with self-interference and fading, which is comprised of a source, an FD relay, destination, where direct source-destination link does not exist impaired by self-interference. For channel, propose three buffer-aided relaying schemes adaptive reception-transmission at for cases when source both perform adaptive-power allocation, fixed-power fixed-rate transmission, respectively. The proposed significantly improve...

Due to random nature of traffic and unpredictability human behaviors, one challenging problems in transportation engineering is congestion which has a direct impact on the economy environment with increase traveling time, fuel consumption emissions. One approaches reduce congestions advance Route Guidance Systems (RGSs) can propose alternative optimal routes for vehicles, are or will be entering congested roads areas. Advanced RGSs, usually employ real-time predicted information find best...

The study of optimal properties centralized dynamic-time-division-duplex (D-TDD) employed at a wireless network consisting multiple nodes is highly challenging and partially understood problem in the literature.

In this paper, we propose optimal centralized dynamic-time-division-duplex (D-TDD) scheme for a general network comprised of K half-duplex (HD) nodes. Specifically, network, adaptive scheduling the reception, transmission, and silence at every node in each time slot such that average sum signal-to-interference-plus-noise-ratio (SINR) is maximized. The numerical results show proposed D-TDD achieves significant SINR gains over existing schemes, especially small crowded areas. can act as an...

The proposed enable to adaptively select either receive, transmit, or...

Connected Vehicle (CV) wireless networks based on DSRC, ITS-G5 and C-V2X technology are susceptible to interference from both unintentional emitters non-CV devices that authorized share the same or adjacent bands. Such may lead unreliable communication disruption of CV services with particular impact safety-related applications. In previous work, we proposed demonstrated congestion (i.e., spectrum misbehavior) in DSRC can be detected simply inexpensively using capabilities already...
