With the integration of technology in higher education, mobile learning plays an important role in EFL classes. In order to optimize the efficiency of EFL learning, a mobile learning model in the hybrid distributed terminal is constructed. The online platform supporting both synchronous and asynchronous learning with three types of interaction helps build a blended learning model and creates a closed loop for ubiquitous online and offline learning with multiple evaluation, which also builds a community of inquiry-based learning to facilitate collaborative study and deep thinking. Aiming to improve the resource scheduling performance of learning information sharing mode, based on the traditional sharing mode hardware, the mobile learning software for the hybrid distributed terminal is thus optimized. Learning resources are mined and fused to realize the scheduling of learning information resources, and user interface management function is designed to construct the EFL mobile learning mode with the hybrid distributed terminal.

“…Shao et al studied the effects of air temperature and humidity, light intensity, CO 2 concentration, and other environmental parameters on the growth process of strawberries, and deeply studied various problems encountered in the growth process of strawberries through the analysis. With PLC as the main controller, a monitoring platform was built through WinCC, and a set of strawberry growth environment monitoring and control system was built by using ProfiNet communication mode, so that the users could query the historical curve of strawberry growth environment parameters, which ensured the healthy growth of strawberries and provided a theoretical basis and practical experience for the development of modernized agriculture [10]. e traditional extensive artificial greenhouse management technology not only consumes huge manpower and material resources, but also requires farmers to spend a lot of time to ventilate, light, fertilize, and irrigate the greenhouse.…”

In order to solve the problems that the production management of agricultural greenhouses consumes large human resources, low management efficiency, and the limitations of environmental monitoring, a visualized smart agriculture based on ZigBee and WiFi dual-protocol fusion Wireless Sensor Networks (WSNs) technology is proposed. A management system is proposed. The system takes STM32 as the main control core and builds a visual cloud computing platform based on the ESP8266WiFi module. The environmental parameters of the greenhouse are sent to the ZigBee terminal device through the serial port, and the user can remotely monitor the environmental parameters of the greenhouse in real time through the computer and mobile client, and control the working status of each actuator. The test results show that: (Transmission Control Protocol/Internet Protocol, TCP/IP) communication is not abnormal; under the control of the visual management system, when the system sends out control commands, the response time of each output terminal is basically between 1 and 2 s. The response of the output control unit has high sensitivity. Affected by the network delay, the fourth group of test data is larger, and in the case of network delay, the response sensitivity of each output terminal of the system decreases accordingly. Conclusion. The system has high accuracy of data collection, strong work reliability, can realize precise remote control, and has low cost, high stability, easy operation, and has certain promotion value.

“…Firstly, this NLoS medium affects the link quality, transmission range, and throughput due to the multipath propagation and hindrance provided by the walls or any other metallic infrastructures. Secondly, as the most widely used operating frequency of Zigbee is 2.4 GHz, which is the same as Wi-Fi, Bluetooth, and Z-Wave, this would create cross technology interference (CTI), which might drastically affect the Zigbee performance [30,31].…”

The recent development of wireless communications has prompted many diversified applications in both industrial and medical sectors. Zigbee is a short-range wireless communication standard that is based on IEEE 802.15.4 and is vastly used in both indoor and outdoor applications. Its performance depends on networking parameters, such as baud rates, transmission power, data encryption, hopping, deployment environment, and transmission distances. For optimized network deployment, an extensive performance analysis is necessary. This would facilitate a clear understanding of the trade-offs of the network performance metrics, such as the packet delivery ratio (PDR), power consumption, network life, link quality, latency, and throughput. This work presents an extensive performance analysis of both the encrypted and unencrypted Zigbee with the stated metrics in a real-world testbed, deployed in both indoor and outdoor scenarios. The major contributions of this work include (i) evaluating the most optimized transmission power level of Zigbee, considering packet delivery ratio and network lifetime; (ii) formulating an algorithm to find the network lifetime from the measured current consumption of packet transmission; and (iii) identifying and quantizing the trade-offs of the multi-hop communication and data encryption with latency, transmission range, and throughput.
