Enhancement in Reliability of IEEE 802.15.4 WBAN Using Greedy Spider Monkey Algorithm Umashankar Pandey, Saroj Kumar Chandra, Narendra Kumar Dewangan International Journal of Networked and Distributed Computing, 2025 Wireless Body Area Networks (WBANs) hold immense potential in healthcare monitoring, but ensuring reliable data transmission is crucial. While the IEEE 802.15.4 standard offers low-power operation and basic security, its Contention-Based Access (CBA) mechanism can lead to packet collisions and reduced reliability, especially in congested scenarios. This paper proposes a novel approach to enhance reliability in 802.15.4 WBANs by incorporating a Greedy Spider Monkey Optimization Algorithm (GSMA). The GSMA mimics the intelligent foraging behaviour of spider monkeys, enabling dynamic channel selection and optimal transmission scheduling. Our approach aims to minimize packet collisions by selecting channels with lower traffic based on historical data and real-time network conditions; the GSMA reduces the likelihood of collisions and data loss. Secondly, the algorithm prioritizes critical data packets based on their urgency and channel availability, ensuring the timely delivery of essential medical information. Finally, by reducing collisions and optimizing scheduling, the GSMA helps maintain efficient data flow within the WBAN. This paper presents the design and implementation of the GSMA-based approach within the 802.15.4 framework. Simulation results are presented to evaluate the effectiveness of the proposed method in improving reliability, reducing packet loss, and enhancing overall network performance in WBANs. The findings demonstrate the potential of the GSMA to address the limitations of 802.15.4 and contribute to developing more reliable and efficient WBAN solutions for healthcare applications.
Improving AI Accuracy: Identifying and Fixing Hallucinations in Large Language Models Nisha Dadoriya, Saroj Kumar Chandra 1st IEEE International Conference on Data Science and Intelligent Network Computing Icdsinc 2025, 2025 The text generation skill of AI models sometimes faces a fundamental limitation because, along with relatable and accurate outputs, it has also been found to generate false information or misleading textual content, affecting their suitability in healthcare, law, or finance. Existing mitigation strategies fall short in specific ways. In our research, we are improving the shortcomings of previous work by performing the AI response by combining three similarity metrics, such as cosine similarity, Jaccard similarity, or BLEU score, as an assessment tool to find hallucination levels. In addition, implementing the SHAP XAI technique works to refine the model by analyzing its responses. We first evaluated the hallucination rate in our dataset using a hybrid simi-larity approach and then employed Shapley Additive Explanation (SHAP) to investigate and reduce it. The outcomes of our analysis demonstrate that SHAP improves the reliability of the model by producing a remarkable reduction in hallucination rates that occur similarly in the score. Quantitative inspection shows that the SHAP input explains the variance, thereby increasing the interpretability and accuracy of the AI model.
DeepFake Image Detection and Classification using EfficientNet Model Sunny Singh, P Sarala, Saroj Kumar Chandra, Mikkili Dileep Kumar 2024 Opju International Technology Conference on Smart Computing for Innovation and Advancement in Industry 4 0 Otcon 2024, 2024 Deep learning models such as Vision Transformer (VIT) and EfficientNet, have brought significant advancements to computer vision tasks like image classification, object detection, and image generation. In this paper, comparative analysis of VIT and EfficientNet models has been done with more attention of on their architectural disparities, training procedures, and performance characteristics. Deep learning models like Vision Transformer (VIT) and EfficientNet have revolutionized computer vision. VIT uses self-attention techniques instead of convolutional layers to capture global relationships but with higher computational. EfficientNet models, with compound scaling offer a trade-off between accuracy and efficiency. EfficientNet models are computationally fast with competitive accuracy and is suitable for resource-limited contexts. The paper suggests choosing the best model based on specific use cases and resource limitations. Quantitative analysis of the present work has been done using confusion matrix. It has been observed that EfficientNet models are providing higher performance ratio.
Efficient Machine Learning and Factional Calculus Based Mathematical Model for Early COVID Prediction Saroj Kumar Chandra, Manish Kumar Bajpai Human Centric Intelligent Systems, 2023 Diseases are increasing with exponential rate worldwide. Its detection is challenging task due to unavailability of the experts. Machine learning models provide automated mechanism to detect diseases once trained. It has been used to predict and detect many diseases such as cancer, heart attack, liver infections, kidney infections. The new coronavirus has become one of the deadliest diseases. Its case escalated in unexpected ways. In the literature, many machine learning models such as Extreme Gradient Boosting (XGBoosting), Support Vector Machine (SVM), regression, and Logistic regression have been used. It has been observed that these models can predict COVID cases early but are unable to find the peak point and deadline of the disease. Hence, mathematical models have been designed to early predict and find peak point and dead-line in disease prediction. These mathematical models use integral calculus-based Ordinary Differential Equations (ODEs) to predict COVID cases. Governments are dependent on these models’ pre- diction for early preparation of hospitalization, medicines, and many more. Hence, higher prediction accuracy is required. It has been found in the literature that fractional calculus-based models are more accurate in disease prediction and detection. Fractional models provides to choose order of derivative with fractional value due to which information processing capability increases. In the present work, mathematical model using fractional calculus has been devised for prediction of COVID cases. In the model, quarantine, symptomatic and asymptomatic cases have been incorporated for accurate prediction. It is found that the proposed fractional model not only predicts COVID cases more accurately but also gives peak point and dead-line of the disease.

Hybrid Image Captioning Model Lipismita Panigrahi, Raghab Ranjan Panigrahi, Saroj Kumar Chandra 2022 Opju International Technology Conference on Emerging Technologies for Sustainable Development Otcon 2022, 2023 Image captioning is implemented using Deep learning and NLP (Natural Language Processing) resulting in producing a description of an image. The proposed model generates a caption for an image using a Convolutional Neural Network (CNN) together with a Recurrent Neural Network (RNN) and area of attention. Previously, the image names were used as keys to map the images with descriptions. In order to achieve high performance, in the proposed model the image caption is based on the relationship between the areas of a picture (attention model), the words used in the caption, and the state of an RNN language model. The approach of progressive loading is employed for the loading of the image dataset. Further, for encoding the image dataset into a feature vector, VGG16 a pre-trained CNN is used. The extracted feature vector is given as input to the RNN model. These image encodings are output to a specific type of RNN model known as Long Short-Term Memory (LSTM) networks. Subsequently, the LSTM works on decoding the feature vector and predicts the sequence of words, resulting in the generation of descriptions or captions. The training performance is measured using one of the model’s quantitative analysis metrics known as BLEU.
