Rainfall Prediction is an integral part of research these days with its applications ranging from Disaster Management to Agricultural Technologies. Coastal cities like Chennai are extremely prone to irregular and incessant bursts of rainfall. Prior knowledge of such events is necessary to avoid wastage of resources and reduce damage to livelihood. In this paper, we have investigated several state-of-art algorithms such as SARIMA, LSTM, BiLSTM, RNN, RNN-LSTM that are used for rainfall forecasting. The investigations show that the state-of-art algorithms have reduced error rates in predictions, however fail to handle extreme rainfall events. To overcome this, an Ensemble Model of CNN, RNN-LSTM, and Bidirectional LSTM are proposed to forecast the daily rainfall statistics of Chennai. The proposed model is compared with the baseline models to analyze its performance. The features considered for model implementation are Rainfall, Relative Humidity, and Temperature that is collected on a daily scale. The evaluation result shows that the proposed model provides improved prediction results for Rainfall when compared to the baseline approaches.

Medical and psychological applications are expected to benefit substantially from the use of Wireless Body Area Networks (WBAN). As the enormous amount of healthcare data evolves, it becomes more and more difficult to locate any meaningful information. Because in view of integrating IoT into almost all fields, including healthcare, animal monitoring and tracking in all sectors, In order for the WBAN-enabled IoT technology to optimise the functioning of healthcare applications, there must be sufficient support from all the protocol stack levels. Therefore, the network layer protocol has lately attracted an excellent deal of attention within the field of WBANs due to its capacity to manage and coordinate the info packets with minimum energy and avoid congestion. This study is to determine the optimum approach, fitness functions for simulated WBAN routing algorithms are evaluated using routing metrics such as PDR and energy under various optimization approaches. Finally, certain open research issues and early research objectives in the domain are identified and compared across various optimization techniques for WBAN routing protocols.

The pandemic situation has greatly affected normal working in various sectors. One of the affected sectors is education. Due to online meeting platforms, there was not much difficulty in conducting theory classes. But the real challenge was conducting the lab classes and exams. We take up the problem of conducting computer programming assessment in online mode. One may argue that computer systems and handheld devices are common nowadays, and there are not many hurdles in handling lab sessions. But conducting a fair assessment is a challenging task. We propose a novel virtual platform with monitoring features to facilitate a smooth assessment. Our platform detects the student's face and verifies if there is any proxy. Further, the platform sends the student's image to the examiner for verification. Our platform detects the number of faces within the camera frame. We include modules to detect if the student uses a mobile phone during the examination. The trained model will be deployed in tensorflow workspace which can be easily integrated into the platform as an API and we have verified the efficiency of the model. We observe a 1.47 loss value, which shows the efficiency and feasibility of our proposed model.

The proper monitoring of ECG will help to identify patients with cardiac problems. In the last two decades, many lives have been saved due to the automated prediction of heart diseases with the help of ECG signals. This article proposes a hybrid CNN-Naive Bayes classifier for classifying Normal Sinus Rhythm, Abnormal Arrhythmia, and Congestive Heart Failure from the MIT-BIH arrhythmia database. The one-dimensional ECG signals are converted to two-dimensional scalogram images using continuous wavelet transform. The scalogram images eliminate noise filtering and conventional feature extraction steps that may lead to loss of beats. The proposed architecture uses GoogLeNet to extract independent and discriminating features, which aids the Naive Bayes classifier to attain a high accuracy of 98.76%.

Breaks down boundaries and inspires creativity. These are just a few examples of how communication affects the world around us. Many successful people use this tremendous tool of communication to change the world, while others with disabilities in speech, hearing, or having multiple disabilities use sign language to change the world. However, the disadvantage of employing sign language is that not everyone would be able to understand it. To address this issue, a sensor-based system is proposed with five flex sensors put on five fingers as binary bits, yielding a total of 32 options in this study. In addition, this proposal includes two options for broadening the reach of terms. This proposed model eliminates the need for other types of sensors besides flex sensors, lowering production costs significantly. It is more accurate and efficient than vision-based approaches because it is sensor-based. Because of this project, people who do not understand sign language can communicate easily with people who have speech or hearing problems.

Wearable and implantable medical devices are revolutionizing health-care today with lab-on-a-chip technologies because they can register a wide range of physiological and environmental parameters. Implantable Medical Devices (IMDs) and Wearable Medical Devices (WMDs) with bio-sensors have modernized the way high-quality, safe health care is delivered. The wearable device is more readily available than IMDs and does not require additional installation expenditures. It is critical to find solutions for battery depletion, resolution, and data prevention in Wearable Medical Devices (WMDs). The purpose of this paper is to provide a strategy for overcoming current wearable technology challenges. SAR-ADC has a flexible binary search approach, good power efficiency, and high resolution, and the recommended system aids in wearable sensor node reconfigurability. Wearable Medical Devices could generate medical data and communicate it via wireless networks to a cloud-based system. During the data transfer to the cloud, the Man in the Middle will steal confidential medical information. Advanced Encryption Standard (AES) methods are active in Wireless Sensor Networks (WSNs) to safety net the data from loss or stealing of data. AES is a hardware-based encryption method that safeguards data from a variety of threats. As a result, the suggested system uses the AES algorithm to transform data that un-encrypted into encrypted data. The 128 bit AES algorithm was used with the XILINX 14.5 software, yielding a result of 7.528 ns minimum time and 296.8MHz frequency, with a throughput of 1.70 GB/s.

Non-Orthogonal Multiple Access (NOMA) is one of the upsurging technologies for the Beyond 5G communication network that finds application in M2M, V2V, and connecting low-power IoT devices. NOMA exploits the multiplexing of signals in the power domain but with the same frequency. The conventional multiple access scheme is Orthogonal Multiple Access (OMA), whose performance is far less efficient when compared to NOMA. Fairness Index (FI) is one of the performance metrics that analyzes the quality of service offered by NOMA and OMA systems. In this paper, the Jain's Fairness Index (JFI) of the NOMA and OMA systems are analyzed with two users and then with more users. For the available bandwidth of 20 MHz with five users, the FI for NOMA is 0.9058, and that for OMA is 0.7087, ensuring the possibility of massive connections with the NOMA system.

In a communication system, pulse shaping filters are used to create a band limited channel and to reduce the Inter Symbol Interference (ISI). Low Density Parity Check Codes (LDPC) code is the improved error correction code used in 5G technology to reduce BER to a great extent. This paper focuses on combining the effect of different pulse shaping filters with the novel rate adaptive irregular LDPC codes. The novel LDPC encoding algorithm having sparse Parity Check Matrix (PCM) is used to achieve capacity nearer to Shannon's Capacity. From the simulation results it is clear that this combination reduces the BER further. It is observed that this idea of combining pulse shaping filters and LDPC can be applied to high data rate communication like 5G in the view of reducing Bit Error Rate (BER).

The wireless communication field is growing tremendously. To achieve the key requirements of future wireless networks, reconfigurable intelligent surface (RIS) assisted communication is a new research direction. RIS consists of more passive reflectors, and it can direct the signal towards the desired user by adjusting the phase shift of passive elements, hence signal-to-noise ratio (SNR) can be improved. The ideal RIS can compensate the channel effects completely. Practically, the compensation of each and every phase of RIS elements is very difficult. In this work, an algorithm for intelligent discrete phase shifter assisted RIS is developed. The proposed algorithm is tested with one-bit and two-bit discrete phase shifters. Discrete phase shifter maps the required phase of RIS elements to discrete phase levels and steers the beam. Through simulations, it is observed that the increase in discrete phase levels and RIS elements offers performance similar to ideal RIS assisted communication.

A stacked microstrip patch antenna using a microstrip feed line for UWB functions has been proposed in this paper. By using two different substrate for assigning the property of stack FR4 and Rogers RT/duroid 5880 with a dielectric constant (εr) of 4.4 and 2.2, respectively, with a gap of 1.5 mm, is assigned. Overall antenna dimensions are 27 mm × 30 mm × 4.7 mm. The concept of EM coupling means that the conduction occurs so that proper matching is desired in this antenna. Multiple slots increase the flow of conductivity in different regions. The simulated results show the bandwidth (B.W) obtained at 3.34 - 4.42 GHz, 6.0012.56GHz GHz with a gain ranging from 4.5 to 8 dB. Throughout this entire region, the proposed antenna provides $mathrm{S}_{11} < -10$ dB.

Overall antenna dimensions are 27 mm × 30 mm × 4.7 mm. The concept of EM coupling means that the conduction occurs so that proper matching is desired in this antenna. Multiple slots increase the flow of conductivity in different regions. The simulated results show the bandwidth (B.W) obtained at 3.34 - 4.42 GHz, 6.0012.56GHz GHz with a gain ranging from 4.5 to 8 dB. Throughout this entire region, the proposed antenna provides $mathrm{S}_{11} < -10$ dB.","PeriodicalId":432794,"journal":{"name":"2022 International Conference on Wireless Communications Signal Processing and Networking (WiSPNET)","volume":"317 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120885932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
