    <span>In wireless sensor network (WSN), the high volume of observe and transmitted data among sensor nodes make it requires to maintain the security. Even though numerous secure data transmission approaches designed over a network, an inadequate resource and the complex environment cause not able to used in WSNs. Moreover, secure data communication is a big challenging problem in WSNs especially for the military application. This paper proposes a dingo algorithm-based forwarder selection and huffman coding (DAHC) to improve authentication in internet of things (IoT) WSN. Initially, it detects the anomalous nodes by applying support vector machine (SVM) algorithm based on sensor node energy, node selfishness, and signal to noise ratio (SNR). Next, we using the dingo algorithm to select the forwarder node. This dingo algorithm computes the fitness function based on node degreee, node distance and node energy. Finally, the huffman coding to provide end to end authentication established on node energy from sender to receiver. During data transmission, the huffman coding to build the binary hop count value, it improves the authentication in the WSN. Performance results specify that this approach enhances the detection ratio and throughput.</span>

  • Investigations of Machine Learning Algorithms for High Efficiency Video Coding (HEVC)
    N Usha Bhanu, C Saravanakumar
    Proceedings of 2023 International Conference on Signal Processing Computation Electronics Power and Telecommunication Iconscept 2023, 2023
    The growing demand of high-resolution video on portable devices, the applications require higher coding efficiency, high throughput and low power for handling heterogenous types of video signals. This paper presents a survey on possibility of applying Machine Learning (ML) models in H.265/ HEVC video encoder unit. Higher computational complexity with respect to motion estimation, coding, and parallel processing architectures are required for HEVC. The existing HEVC algorithms are based on spatial temporal relationship which requires dynamic video sequences handling for fast changes in scenes. This paper focuses on the possible realization of machine learning algorithms for Rate Control (RC) in video sequences, Coding Unit (CU) depth decision, Neural network-based Motion Estimation and Compensation, adaptive de-blocking filter for reducing blocking artifacts and task driven semantic coding for real time video applications. The algorithms are surveyed with respect to the learning process used in various units of HEVC encoders and summarized in terms of parameters achieved and datasets used in the existing literature.
  • Validation of Adder blocks with Shared Resource Methodology for Precise Cell Boundary Identification in Biotechnology Applications

    For quantitative single-cell biology using optical microscopy, locating cells in a microscopic image is critical. Although there are several segmentation methods available, successful segmentation is difficult and typically necessitates problem-specific algorithm tweaking. Furthermore, recent algorithms are dependent on a few fundamental methodologies that detect cell borders using the image's gradient field. Many microscopy procedures, on the other hand, can provide pictures with distinct intensity patterns at the cell membrane. This has yet to be leveraged algorithmically to develop more generic segmentation approaches. In the proposed work, a simple algorithm is employed to identify the boundary of a cell in a microscopic image and it is deployed in a hardware chip to experiment with it. The results show the isolation of boundaries of the cell with improvement in the area occupied by the hardware. The resource-sharing technique is employed to reduce the area by 50 - 60% without compromising the identification of the boundary of the cell in the microscopic image.
  • A Constructive approach to Numerical Mapping scheme of Nucleotides for Preprocessing in Machine Learning
    C Saravanakumar, N Usha Bhanu
    Proceedings of the Confluence 2022 12th International Conference on Cloud Computing Data Science and Engineering, 2022
    One of the major issues in the Bioinformatics discipline is to construct a method by which the precise protein-coding region can be identified in the intended nucleotide series. The exact spotting of protein coding regions in a nucleotide is valuable in numerous entities. For an instance, it aids in describing unique proteins, develop drugs, and furthermore in uncovering the developmental foundation of a specific living being. Digital Signal Processing (DSP) rooted technique is quite popular for identifying protein coding regions. The main fundamental stage of the DSP oriented prediction of exon, is to direct the nucleotide base to the numeric values. Choosing a numerical mapping configuration influences the characteristics of the DNA sequence, helping them to pinpoint the precise area of the exon. Over the most recent twenty years, a number of methods to map the nucleotides have been effectively utilized as a preprocessing stage for exon prediction. The proposed method of mapping a sequence outerforms other schemes in predicting the region of exons.
  • Fog Managed Data Model for IoT based Healthcare Systems
    Benila S Benila S, Usha Bhanu N. Benila S
    Journal of Internet Technology, 2022
    <p>In Internet of things enabled healthcare system, sensors create vast volumes of data that are analyzed in the cloud. Transferring data from the cloud to the application takes a long time. An effective infrastructure can reduce latency and costs by processing data in real-time and close to the user devices. Fog computing can solve this issue by reducing latency by storing, processing, and analyzing patient data at the network edge. Placing the resources at fog layer and scheduling tasks is quite challenging in Fog computing. This paper proposes a Fog Managed Data Model (FMDM) with three layers namely Sensor, Fog and cloud to solve the aforementioned issue. Sensors generate patient data and that are managed and processed by Fog and cloud layers. Tasks are scheduled using a Weighted Fog Priority Job Scheduling algorithm (WFPJS) and fog nodes are allocated based on Priority based Virtual Machine Classification Algorithm (PVCA). The performance of this model is validated with static scheduling techniques with variable patient counts and network configurations. The proposed FMDM with WFPJS reduces response time, total execution cost, network usage, network latency, computational latency and energy consumption.</p> <p> </p>
