“…The primary goal of deploying IoT applications is to produce high observations in real-time, which is too difficult due to the resource constraints, the limited computing power of sensors, such as speed, energy, bandwidth, computation, ands memory, and a large volume of heterogeneous, high-speed WSN data [18]. Imran et al [87] have outlined a few key challenges in IoT and sensing technologies, as well as key issues such as self-organization, energy efficiency, security and scalability that must be considered when utilizing these newer technologies for the benefit of the society. Furthermore, advances in sensing technologies will pave the way for successful IoT solutions, as discussed in this article, and would support a variety of sectors, including healthcare, buildings, transportation, education, supply chains with many other fields of our everyday lives.…”

Recently, Internet of Things (IoT) technologies are developing technology with a variety of applications. The Internet of Things (IoTs) is defined as a network of ordinary objects such as Internet TVs, smartphones, actuators and sensors that are smartly connected together to enable new types of communication between people and things as well as between things themselves. Wireless sensor networks (WSNs) play an important part in Internet of Things (IoT) technology. A contribution to wireless sensor networks and IoT applications is wireless sensor nodes’ construction with high-speed CPUs and low-power radio links. The IoT-based wireless Sensor network (WSN) is a game-changing smart monitoring solution. ZigBee standard is an important wireless sensor network (WSN) and Internet of Things (IoT) communication protocol in order to facilitate low-power, low-cost IoT applications and to handle numerous network topologies. This paper presented a review on the energy efficient and routing topologies of ZigBee WSN, applications of IoT enabled Wireless Sensor Network as well IoT WSN security challenges.

“…The increased usage of WSs associated with IoT devices have increased the challenges in fulfilling the enduser demands. Standardizing technology, energy efficiency, handling heterogeneous traffic, reducing cost in the design of WS nodes, securing user information, etc., are some of the challenges that are being faced by WSs [101]. In our recent Newsletter, we have showed that the combined use of Multiple-Input-Multiple-Output (MIMO) and Intelligent Reflecting Surfaces (IRS) (see Fig.…”

The addition of massive machine type communication (mMTC) as a category of Fifth Generation (5G) of mobile communication, have increased the popularity of Internet of Things (IoT). The sensors are one of the critical component of any IoT device. Although the sensors posses a well-known historical existence, but their integration in wireless technologies and increased demand in IoT applications have increased their importance and the challenges in terms of design, integration, etc. This survey presents a holistic (historical as well as architectural) overview of wireless sensor (WS) nodes, providing a classical definition, in-depth analysis of different modules involved in the design of a WS node, and the ways in which they can be used to measure a system performance. Using the definition and analysis of a WS node, a more comprehensive classification of WS nodes is provided. Moreover, the need to form a wireless sensor network (WSN), their deployment, and communication protocols is explained. The applications of WS nodes in various use cases have been discussed. Additionally, an overlook of challenges and constraints that these WS nodes face in various environments and during the manufacturing process, are discussed. Their main existing developments which are expected to augment the WS nodes, to meet the requirements of the emerging systems, are also presented.

“…The conventional antenna ended up with poor upward radiation from 1 to 4 . Nevertheless, regarding the OFAA, the initial geometry started from 2 to 5 with no AMC, but evolved through 3 to 6 , thereby accomplishing the desirable upward radiation with a high strength due to the film-type AMC. This advantage was obtained when using the proposed antenna, but not the other metamaterials.…”

In this paper, a novel thin and flexible antenna is proposed for earbuds to gain an improvement in their wireless signal-sensing capability as a film-based artificial magnetic conductor (AMC) structure. As antenna designs for earbuds face challenges of being embedded beneath the top cover of the earbud, conformal to curved surfaces, and very close to metallic ground and touch-panel parts, as well as scarce degrees of freedom from feeding conditions and functional degradation by human tissue, unlike conventional techniques such as quasi quarter-wavelength radiators on LDS and epoxy molding compounds (relatively thick and pricy), an antenna of a metal pattern on a film is made with another film layer as the AMC to mitigate problems of the antenna in a small and curved space of an insert-molded wireless device. The antenna was designed, fabricated, and embedded in earbud mockups to work for the 2.4 GHz Bluetooth RF link, and its functions were verified by RF and antenna measurement, showing that it could overcome the limitations in impedance matching with only lumped elements and poor radiation by the ordinary schemes. The input reflection coefficient and antenna efficiency were 10 dB and 9% better than other methods. In particular, the on-film AMC antenna (OFAA) presents robustness against deterioration by the human tissue, when it is placed in the ear phantom at the workbench and implemented in an in situ test using a large zorb ball mimicking a realistic sensing environment. This yielded an RSSI enhancement of 20–30 dB.
