Internet of Underwater Things (IoUT) is regarded as the network interconnected smart underwater objects that enables marine monitoring and exploration. acoustic sensor networks (UASNs) an ideal infrastructure to support IoUT. Usually, network-level analysis requires a simplified model for channel interference. Existing research on UASNs usually applies interference models from terrestrial wireless networks. Its effectiveness questionable. In this article, we investigate two specific features...
Underwater acoustic communication network (UACN) has been considered as an essential infrastructure for ocean exploitation. Performance analysis of UACN is important in underwater deployment and management. In this paper, we analyze the throughput three-dimensional randomly deployed transmitter–receiver pairs. Due to long delay channels, complicated networking protocols with heavy signaling overhead may not be appropriate. consider only one-hop or two-hop transmission, save cost. That is,...
A guard time is a short interval that added between packet transmissions, and has been applied in time- slotted underwater acoustic sensor networks (UASNs) to balance the transmission rate inter-slot interference. In this article, we take physical-layer approach investigate throughput performance time-slotted UASN with time. Based on geographical node distribution, first derive probability distribution of arrival an interfering further overlap duration. We then expression density functions...
This article proposes a directional antenna-based routing scheme for airborne networks with noncooperative eavesdroppers. The metric of route selection is to maximize the path availability time and lower risk communication exposure eavesdropper. First, based on motion pattern eavesdropper, we introduce concept beam lifetime. lifetime defined as duration from current when eavesdropper perceives signal. Furthermore, indicate minimum along path. Each forwarding node (FN) records in table....
In this paper, we consider a finite network of multiple mobile autonomous underwater vehicles (AUVs) collecting data in given region and transferring them to surface sink. All AUVs patrol cylindrical dynamically control their 3-Dimensional (3D) location according the random way-point (RWP) mobility model. Our specific interest focuses on system throughput under different locations serving AUV. The following three AUV selection policies are investigated: 1)The is closest among all active...
Abstract Background Older adults are more susceptible to the novel coronavirus disease 2019 (hereafter, COVID-19) and likely develop severe illness. Cytokine release syndrome (CRS) may be an important factor in development of patients with COVID-19. Interleukin-6 (IL-6) is cytokine CRS, tocilizumab can block IL-6 receptor. In this study, we analyzed therapeutic effects safety on CRS older Methods Between February 10 March 21, 2020, a total 19 or critical COVID-19 aged ≥ 60 years met study...
The design and performance analysis of underwater acoustic sensor networks (UASNs) have attracted intensive attention. In this study, we present a theoretical framework to evaluate the performances UASNs. contrast existing methods, applied new communication protocol model characterize channel interference by taking into account unique characteristics channels, namely, concurrent transmission opportunities owing large propagation delays signals. Using model, investigated collision regions...
In this paper, we consider a finite network of multiple mobile autonomous underwater vehicles (AUVs) collecting data in given region and transferring them to surface sink. Herein, serving AUV located at fixed sea depth communicating with the Further, all AUVs other than are considered as interfering assumed be 2-dimensional circular area radius. We further assume that dynamically control their horizontal position over time. The instantaneous is regarded random process. apply general waypoint...
