Special Issue Information

Dear Colleagues,

Within the background of the human information era, the rapid development of Internet of Things (IoT) technology has led to higher requirements for wireless communication technology in environmental monitoring—that is, it is necessary to realize high-speed and high-quality communication in a more complex environment network. As the most basic and important type of information acquisition, sensor technology has greatly developed in recent years. Wireless sensor networks (WSNs) with sensing, computing, and communication capabilities have broad prospects and high application value. However, problems such as sensor cost, sensor reliability, communication security, maintenance, and data processing still remain bottlenecks for the use of WSNs for environmental monitoring. With the advancement of microelectronic technology, intelligent sensors have been developed to detect, judge, and process complex environmental information, providing us with promising solutions.

This Special Issue aims to collect innovative developments in areas related to the use of WSNs and wireless communication technology for environmental monitoring, including but not limited to the following topics:

cost (of node, energy consumption, maintenance);

energy (self-powered sensors, stability, environmental protection);

communication (security, scalability);

data processing (distributed, big data, robustness);

WSNs design and validation;

Artificial intelligence in WSNs;

Industrial WSNs;

Body Sensor Networks;

Flexible sensors;

Novel sensor device for WSNs.

Since the evaporation duct height (EDH) only covers the antenna height of most shipborne microwave radars, mastering the EDH in advance has great significance in achieving long-range target detection. In this paper, a set of hydrological and meteorological sensors based on the gradient meteorological instrument (GMI) were built to monitor the evaporation duct of the South China Sea (SCS). However, the monitoring needed to be interrupted during the battery replacement of the sensor, which could result in the loss of some important data collection. On the basis of the inductively coupled power transfer (ICPT) technology, the resonance principle was used to compensate the inductive reactance on the closed steel ring (CSR), and the energy stored in the super capacitor was introduced for data collection and return. A novel measuring system for the detection of an evaporation duct was proposed. To avoid iterative calculation by setting the initial value of the current evaporation duct models in large-scale and multi time evaporation duct prediction and diagnosis, on the basis of the non-iterative air–sea flux (NAF) model, the EDH was obtained by introducing the K theoretical flux observation method into the atmospheric refractive index equation. Finally, preliminary experimental results are presented for the detection of evaporation duct to demonstrate the feasibility and effectiveness of the proposed system. The communication accuracy rate of the proposed system was 99.7%. The system transmission power reached 22.8 W. The research results of the NAF model adaptability showed that the mean value of the EDH was 8.7 m, which was lower than the mean EDH of the SCS. The EDH calculated by the NAF model in the unstable air–sea stratification state was slightly lower than that calculated by the NPS model. The diagnosis of the EDH by the NAF model was similar to that of the NPS model, but the calculation stability of the NAF model was better. Full article

Considering that the actual operating environment of UAV is complex and easily disturbed by the space environment of urban buildings, the RoutE Planning Algorithm of Resilience Enhancement (REPARE) for UAV 3D route planning based on the A* algorithm and artificial potential fields algorithm is carried out in a targeted manner. First of all, in order to ensure the safety of the UAV design, we focus on the capabilities of the UAV body and build a risk identification, assessment, and modeling method such that the mission control parameters of the UAV can be determined. Then, the three-dimensional route planning algorithm based on the artificial potential fields algorithm is used to ensure the safe operation of the UAV online and in real time. At the same time, by adjusting the discriminant coefficient of potential risks in real time to deal with time-varying random disturbance encountered by the UAV, the resilience of the UAV 3D flight route planning can be improved. Finally, the effectiveness of the algorithm is verified by the simulation. The simulation results show that the REPARE algorithm can effectively solve the traditional route planning algorithm’s insufficiency in anti-disturbance. It is safer than a traditional A* route planning algorithm, and its running time is shorter than that of the traditional artificial potential field route planning algorithm. It solves the problems of local optimization, enhances the UAV’s ability to tolerate general uncertain disturbances, and eventually improves resilience of the system. Full article
