The Internet of Things (IoT), being a “network of networks”, promises to allow billions of humans and machines to interact with each other. Owing to this rapid growth, the deployment of IoT-oriented networks based on mesh topologies is very attractive, thanks to their scalability and reliability (in the presence of failures). In this paper, we provide a comprehensive survey of the following relevant wireless technologies: IEEE 802.11, Bluetooth, IEEE 802.15.4-oriented, and Sub-GHz-based LoRa. Our goal is to highlight how various communication technologies may be suitable for mesh networking, either providing a native support or being adapted subsequently. Hence, we discuss how these wireless technologies, being either standard or proprietary, can adapt to IoT scenarios (e.g., smart cities and smart agriculture) in which the heterogeneity of the involved devices is a key feature. Finally, we provide reference use cases involving all the analyzed mesh-oriented technologies.

This paper presents a compact and planar ultra‐wideband (UWB) antenna, designed and characterized for the wearable Internet of Things (IoT) devices and wireless body area network (WBAN) applications. Two different substrates, ie, FR4 (h = 1.6 mm) and denim textile substrate (h = 1 mm), are used in the process of design and fabrication of the proposed antenna. The dimensions of the proposed antenna are 31 mm × 42 mm for FR4 substrate and 70 mm × 56 mm for denim textile substrate. The antenna structure consists of a rectangular radiating patch with two symmetrical staircase‐shaped slits. A reduced ground plane technique is used for the purpose of improving impedance bandwidth, which is further enhanced by the insertion of a small notch in the reduced ground plane which has improved the overall impedance matching characteristics of the proposed UWB antenna. The measured impedance bandwidth for S11 < −10 dB and gain of the FR4 and denim textile substrate UWB antennas are 7.71 GHz/5.12 dBi and 7.95 GHz/3.57 dBi, respectively. The ADS momentum simulator is used for antenna simulations, and the simulated and measured results are generally found in good agreements.

Energy management is one of the foremost priorities of research in many countries across the world. The introduction of modern information and communication technologies (ICT) are transforming the existing power grid, towards a more distributed and flexible "Smart Grid" (SG). The wireless sensor networks (WSN) are considered for data communication and are generally, incorporated with actuators to implement the control actions remotely. The wireless technologies like ZigBee (for automation), WiFi (for internet) and Bluetooth (entertainment) work in the 2.4GHz band. The coexistence of different wireless technologies working in the common area is unavoidable. Hence, this phenomenon degrades the performance of each other, due to the interference phenomenon. The wireless nodes with high energy had a great influence on the performance of the nodes working with low energy. Under the influence of interference, the low-power nodes experience the uncertain sleep-wake scheduling and increased delays in channel occupation. Interference also results in, high packet error rates (PER), decreased throughput, and high energy consumption. Hence for overcoming the above problems, A collaborative framework for an effective interference management and its avoidance is proposed in this paper. The framework proposed assures the effective ZigBee communication by systematic channel scheduling operating even under the influence of Wi-Fi. The work proposed performs better even under extreme interference conditions and the results obtained shows enriched performance.Index Terms-Advanced data communications, Home area networks, Interference, Smart meter, The 2.4GHz frequency band, Wi-Fi, ZigBee.
