“…In addition, the ECG signals can truly react the emotion of individuals, because it is difficult for individuals to mask the change on ECG signals. In our future work, we will apply radio sensing techniques, such as [13], [29]- [32], instead of wearable devices for emotion recognition. We will also develop privacy preservation algorithms [33]- [36] to protect the users' privacy.…”

Various emotions can produce variations in electrocardiograph (ECG) signals, distinct emotions can be distinguished by different changes in ECG signals. This study is about emotion recognition using ECG signals. Data for four emotions, namely happy, exciting, calm, and tense, is gathered. The raw data is then de-noised with a finite impulse filter. We use the Discrete Cosine Transform (DCT) to extract characteristics from the obtained data to increase the accuracy of emotion recognition. The classifiers Support Vector Machine (SVM), Random Forest, and K-NN are explored. To find the optimal parameters for the SVM classifier, the Particle Swarm Optimization (PSO) technique is used. The results of the comparison of these classification methods demonstrate that the SVM approach has a greater accuracy in emotion recognition, which may be applied in practice.

“…Aside from that, range accuracy might be impacted by the Non-Line of Sight (NLOS) problem, which occurs when an impediment blocks the direct sight from the anchor node to the target. Besides the above mentioned methods, emerging radio sensing techniques, such as [12]- [15] can also be used for indoor positioning.…”

We examined UWB-based indoor location in conjunction with a fingerprint technique in this work. We built a connection between the measured and real distances for the UWB indoor positioning system. This connection is used to produce a distance database that may be used to generate fringerprints. We created a BP neural network to classify the target node to the relevant fringerpint using the distance database. Our suggested deep learning technology considerably enhances location accuracy when compared to existing trilateration systems.

“…This system has established two edge networks based on LoRa and Wi-Fi respectively and has deployed several functional applications based on different wireless protocols, such as indoor positioning [12], [13] based on UWB and BLE, ECG monitoring device [14]- [18] based on Bluetooth, and people flow statistics based on ultrasonic and Wi-Fi. In the future work, radio sensing techniques, e.g., [19]- [22], can also be used in our system.…”

With the rapid development of smart devices and the Internet of Things (IoT) technology, some traditional scenarios are exploring new possibilities. Especially in the field of healthcare, the mixed and large amount of people, the complex and professional data, and the strict environmental requirements on some medical scenes and equipment, all put forward extremely high requirements on the hospital management. Therefore, an efficient and secure Internet of things system is greatly necessary. This paper develops an IoT system that could be deployed in hospitals for various applications. This system supports LoRa, Wi-Fi and other data collection methods, uploads the data to the cloud platform for further processing through secure connection, and finally feeds back to users in real-time through the user interface. This system supports accurate indoor positioning based on UWB, ECG signal detection, environmental monitoring, people flow statistics and other functions.
