On Throughput for UAV Relay Assisted for Use in Disaster Communications

In this paper, the system performance of an energy harvesting (EH) unmanned aerial vehicle (UAV) system for use in disasters was investigated. The communication protocol was divided into two phases. In the first phase, a UAV relay (UR) harvested energy from a power beacon (PB). In the second phase, a base station (BS) transmitted the signal to the UR using non-orthogonal multiple access (NOMA); then, the UR used its harvested energy from the first phase to transfer the signal to two sensor clusters, i.e., low-priority and high-priority clusters, via the decode-and-forward (DF) technique. A closed-form expression for the throughput of the cluster heads of these clusters was derived to analyze the system performance. Monte Carlo simulations were employed to verify our approach.

Social media for emergency messaging with youth and families during the coronavirus 2019 (COVID-19) pandemic: Getting it right

Disaster communications are frequently included as an area of improvement in the majority of incident after action reports. One segment of the population that is overlooked or intentionally excluded from messaging constructs is adolescents and transitional aged youth. Social media, the preferred mechanism of this population, has the capacity to both educate as well as misinform. Thoughtful and intentional utilization of social media channels for adolescent audiences can convey facts and motivation for appropriate community action when mindfully incorporated into a crisis communication plan by emergency managers. Increasing methods of accurately conveying life-safety issues during the COVID-19 pandemic and its increasing variants must be done correctly and timely.
