This book provides detailed descriptions of downlink non-orthogonal multiple transmissions and uplink non-orthogonal multiple access (NOMA) from the aspects of majorly used 5G new radio scenarios and system performance. For the downlink, the discussion focuses on the candidate schemes in 3GPP standards which are not only applicable to unicast services but also to broadcast/multicast scenarios. For the uplink, the main target scenario is massive machine-type communications where grant-free transmission can reduce signaling overhead, power consumption of devices and access delays. The design principles of several uplink NOMA schemes are discussed in-depth, together with the analysis of their performances and receiver complexities. In the communications industry, greater interest is seen in the innovative upgrade of the systems by integrating advanced wireless and network technologies of 5G.

Wireless Sensor Networks (WSNs) and the Internet of Things (IoT) are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are open challenges that need to be tackled for the future generation of WSNs, and this book gives answers to some of the important questions that need to be answered. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet.

This reference distills information about emerging technologies and applications for smart city design and sustainable urban planning. Chapters present technology use-cases that have radical novelty and high scalability with a prominent impact on community living standards. These technologies prepare urban and rural dwellings for the transformation to the smart world. Applications and techniques highlighted in the book use a combination of Artificial Intelligence (AI) and IoT technologies in areas like transportation, energy, healthcare, education, governance, and manufacturing, to name a few. Machine Learning Process of smart building (SB). ML techniques are successfully trained to solve computer vision problems like speech recognition, gesture recognition, compression, etc which gives greater scope for such models to be applied in smart building context as smart building problems cannot be solved by conventional methods but the appropriate solution could be learned only from data.
