Connectivity is probably the most basic building block of IoT paradigm. Up to now, two main approaches provide data access things have been based on either multihop mesh networks using short-range communication technologies in unlicensed spectrum, or long-range legacy cellular technologies, mainly 2G/GSM/GPRS, operating corresponding licensed frequency bands. Recently, these reference models challenged by a new type wireless connectivity, characterized low-rate, transmission sub-gigahertz...
Low-Power Wide Area Networks (LPWANs) are continuously gaining momentum as fundamental enablers of the Internet Things (IoT) paradigm.

Time-sensitive communications (TSC) in wireless networks is an emerging paradigm that gains research momentum as enabler of the industrial Internet Things. As compared to ultra-reliable low-latency (URLLC) fifth-generation cellular networks, TSC has stricter requirements terms latency and reliability, also demands absolute time-synchronization on-time delivery packets for deterministic isochronous real-time applications. In this regard, a key question how schedule traffic flows effectively....
Data duplication is studied as a fundamental enabler for ultra-reliable low-latency communication (URLLC) in fifth-generation cellular systems. It entails the simultaneous usage of multiple radio links delivering redundant data between terminal and network to boost transmission reliability. However, improved reliability comes at cost reduced spectral efficiency, since instances message on different occupies more resources compared sending only one instance using single link. therefore...
