“…8 When we use high frequency and low wavelength then small size antennas are sufficient for data transmission (where a simple microstrip patch antenna can be utilized). One of the major advantage of FR-2 band is that up and down link powers can be enhanced as and when needed and provides better flexibility for the users who are propagating from ground stations 9 As the frequency range of transmission is increased we observe signal getting weak or even collapsed because of large buildings but they have a better capacity because we can come up with more frequencies under this spectrum so broad frequency bands can be created which permits to carry a lot of information. With the help of cellular network device to device communication can be enabled, the data transformation is propagated through nearest base stations so base station traffic load can be reduced, efficient utilization of spectrum is enhanced, power utilization is reduced, and reduction in latency is also observed.…”

The article proposes a microstrip patch antenna for vehicular communication applications under 5G communication frequency band. The dimensions of the antenna play an important role in the field of vehicular communication applications. The antenna dimensions are optimized by introducing back propagation algorithm. Overall dimension of the antenna is reduced by 16% as compare to the traditional formulations. Further fractal geometry is implemented on the patch and recessed ground as defected ground structure. FR4 epoxy is used to construct the substrate of the proposed antenna with the dimensions of 50 mm × 60 mm × 1.6 mm and the patch is designed as rectangular patch with H‐cut and I‐cut. The proposed antenna is simulated using Ansys high frequency structure simulator v15 and the frequency of operation is 27 to 33 GHz. The antenna parameters such as reflection coefficient, voltage standing wave ratio, gain, radiation, and current distribution are investigated. The antenna is designed in compact in shape such that it is suitable for vehicular communication applications.

“…Furthermore, the probability of collisions is further reduced by using clustering and only selecting cluster heads for multihop transmissions. Reference [32] proposed a multi-hop algorithm for a Massive Input Massive Output (MIMO) system that maximizes the Signal to Noise Ratio (SNR) to determine the best path between the source and the destination.…”

Fog-Assisted Cooperative Protocol for Traffic Message Transmission in Vehicular Networks

Traffic information exchange between vehicles and city-wide traffic command center will enable various traffic management applications in future smart cities. These applications require a secure and reliable communication framework that ensures real-time data exchange. In this paper, we propose a Fog-Assisted Cooperative Protocol (FACP) that efficiently transmits uplink and downlink traffic messages with the help of fog Road Side Units (RSUs). FACP divides the road into clusters and computes cluster head vehicles to facilitate transmission between vehicles and traffic command center or fog RSUs. Using a combination of IEEE 802.11p and C-V2X wireless technologies, FACP minimizes the time required by a vehicle to retrieve traffic information. Furthermore, FACP also utilizes cooperative transmissions to improve the reliability of traffic messages. Simulations results show that FACP improves the reception rate and endto-end delay of traffic messages.

“…Indeed, if the number of hop is 𝐾, the maximum e2e throughput is 1/𝐾, i.e., one data per 𝐾 time slots. Although published works [4], [6]- [8] proposed various diversity-based MHR approaches (i.e., path selection [4], relay selection [6], transmit antenna selection (TAS)/selection combining (SC) [7], [8]) for performance enhancement, the obtained e2e throughput is still 1/𝐾.…”

This paper measures end-to-end (e2e) throughput of power beacon-assisted multi-hop decode-and-forward (DF) relaying scheme adopting non-orthogonal multiple access (NOMA) and transmit antenna selection (TAS)/selection combining (SC). Particularly, TAS/SC and NOMA are adopted at each hop to relay different data of a source to multiple destinations. Moreover, the transmitters including source and relays have to harvest wireless energy from radio frequency (RF) signals from a power beacon. We also propose a simple and efficient power allocation method for the signals transmitted at each hop. For performance measurement and comparison, we provide closed-form formulas of the e2e throughput over Rayleigh fading channel. We then verify our derivations by computer simulations as well as compare the e2e throughput performance between our scheme and the corresponding one that does not use NOMA.
