<p>To effectively reduce the cost of firmware upgrade and maintenance of embedded devices, according to the requirement of a remote firmware update of embedded devices, this paper proposes a remote online firmware upgrade technology based on ZigBee. Combined with the requirements of remote online firmware upgrade application of tower-mounted amplifier, this paper analyzes and studies the system requirements, ZigBee module selection and design, software design and implementation (communication protocol design of host and slave program, breakpoint continuation function), fault analysis and other aspects. Designed experiments and tested the ZigBee connection success rate under the device startup state and normal operation state, the relationship between transmission firmware size and transmission success rate, system CPU resource consumption, transmission distance, transmission rate, the success rate, data reuse rate and acceleration ratio of breakpoint continuation function, and other performance indicators. The experimental results show that the remote online firmware upgrade technology based on ZigBee for embedded devices can better meet the system’s performance requirements in all aspects and improve the data reuse rate and acceleration ratio in the process of data transmission. The experimental results show that this scheme has the advantages of simplicity, low cost, high reliability, and broad application prospects.</p> <p> </p>

Zigbee is a very popular technology for Internet of things (IoT) networks mainly because of its low power consumption and low-cost features. It shares the unlicensed 2.4 GHz Industrial, Scientific, and Medical (ISM) radio band with other wireless networks such as Wi-Fi. Usually, Zigbee and Wi-Fi networks coexist in indoor environments for their respective applications. Hence, the coexistence introduces interference for both types of networks lowering the performance of the networks, but Zigbee suffers more significant performance losses because of its lower transmission power than Wi-Fi. Since the number of IoT devices is increasing at an unprecedented rate due to numerous emerging applications and thus making the indoor environments very populous, the peaceful coexistence between Zigbee and Wi-Fi networks in proximity becomes an important research study. For this purpose, this paper presents a comprehensive performance study of a Zigbee network in the presence of a Wi-Fi interference network in a real-life apartment-based indoor environment where Wi-Fi access points of dense neighbors exist. The experiments were done in a XBee module-based Zigbee network for measuring the received signal strength indicator (RSSI), packet drop rate (PDR), and loopback throughput with and without nearby Wi-Fi traffic introduced on purpose. Various networking parameters such as the operating channels, the distances between Zigbee devices and Wi-Fi devices, the transmit timeout of Zigbee packets, and the transmission power of the Zigbee transmitter have been used in the experiments to study the network performance. Our results show that in the deployment of IoT networks in a smart home, radio interference from neighboring homes would not be an important factor, but serious considerations may need to be taken inside the same home. The experimental observations of this paper can serve as a good reference study for Zigbee network deployments in real indoor environments, particularly when interference sources are present in proximity.

“…The range of the Zigbee network can be increased by implementing multi-hop communication topologies (adding intermediate nodes), which implies an increase in the cost of the system, as well as in the installation time. In addition, interference can occur between Zigbee networks operating in the 2.4 GHz industrial, scientific, and medical radio band (ISM band) and Wi-Fi networks operating in the same or adjacent frequency channels, which usually overlap Zigbee channels due to the wide bandwidth of Wi-Fi communications [ 19 ].…”

The present study exposes an economical and easy-to-use system to assess the heat transfer in building envelopes by determining the U-value. Nowadays these systems require long wires and a host to collect and process the data. In this work, a multi-point system for simultaneous heat flux measurement has been proposed. The aim is to reduce the long measurement time and the cost of thermal isolation evaluations in large buildings. The system proposed consists of a low-cost 3D-printed heat flux sensor integrated with a LoRa transceiver and two temperature sensors. The heat flux (HF) sensor was compared and calibrated with a commercial HF sensor from the Fluxteq brand.
