Security and Privacy Issues of Medical Systems in Wireless Sensor Networks: A Survey
No full textFor decades, the wireless medical sensor network (WMSN) has shown great prospective in refining health care quality. The vast ranges of medical applications that lead to computer-assisted treatment from all over the health monitoring are based on WMSNs technology. These applications introduce emergency medical response systems with its numerous advantages and facilities. However, these technologies have privacy and security challenges that need to be analyzed to make it preferable and socially acceptable. This survey paper depicts the current state-of-the-art wireless sensor network (WSN) technologies being used in medical applications. In this paper, we have focused on system architecture, routing, security, and privacy issues with various medical applications from various research work

A Single-Fed Multiband Antenna for WLAN and 5G Applications
No full textIn this paper, a slotted conical patch connected to a small triangular patch multiband antenna for both microwave and millimeter-wave applications is presented. The designed antenna has three characteristics. The proposed antenna is a multiband, having a compact size of 0.35λ0 × 0.35λ0 × 0.004λ0 at its lowest operational frequency, i.e., 2.4 GHz, and more importantly, it can cover both the microwave and millimeter-wave bands with a single feeding. According to the −10 dB matching bandwidth, experimental results show that the antenna operates at (2.450–2.495) GHz, (5.0–6.3) GHz, and (23–28) GHz. The reduced size, simple design, and multiband large bandwidth are some of the advantages over the reported designs in the latest literature. Both simulated and experimental results show a good agreement, and the proposed antenna can be used for wireless local area network (WLAN) applications and fifth-generation (5G) wireless communication devices
