The wireless networks do not consider ultra-high reliability and low latency (URLL) as the primary factors. There is a delay-tolerant, non-critical content and services that are based on human-centric communication in mobile networks. The focus of the wireless networks is to provide boosted rate in data speed and increasing network coverage by using the best networking approach. The wireless communication device is primarily concerned with determining the entity’s status, by offering enhanced wireless connection assistance, and thereby raising the commodity’s status. Additionally, there will be occurrence of traffic in an infrequent manner. This adds pressure for the delivery of packets that are large or medium-sized at low latency. This is not provided by the current wireless technology system’s state of the art. This is a vital factor that challenges the future development of the wireless system for communication. Thus, to have high reliability with the irregular traffic patterns, there is a need for the development of novel and innovative technologies from physical to the network layer in the wireless communication systems. In this paper, technologies like multiple-access scheme, synchronization, multiplexing, full-duplex transmission, and channel code design are introduced for spectrally systematic ultra-high reliability and low latency communication (URLLC) in the physical layer. The techniques developed for the purpose of monitoring and controlling plant growth are called precision agricultural techniques. These techniques use actuators and sensor networks to monitor and control plant growth. Precision agriculture involves smart irrigation and fertilizer monitoring. This paper also develops a new precision agriculture technique using wireless sensor network (WSN). The WSN uses the Message Queuing Telemetry Transport (MQTT) protocol. This WSN uses IoT technology for connecting devices with the sensors for the purpose of monitoring, collecting, and distributing the data. The IoT integrates with cloud computing to subdue the limitations of IoT in monitoring and controlling systems. Thus, this paper involves the development of the UHLL communication system that can be used in precision agriculture using WSNs. © 2021 Elsevier B.V., All rights reserved.
