DSNFyS: Deep Stacked Neuro Fuzzy System for Attack Detection and Mitigation in RPL based IoT
Статья научная
The Routing Protocol for Low-Power and Lossy Networks (RPL) is a widely adopted protocol for managing and optimizing routing in resource-constrained Internet of Things (IoT) environments. RPL operates by constructing a Destination-Oriented Directed Acyclic Graph (DODAG) to establish efficient routes between nodes. This protocol is designed to address the unique challenges of IoT networks, such as limited energy resources, unreliable wireless links, and frequent topology changes. RPL's adaptability and scalability render it particularly suitable for large-scale IoT deployments in various applications, including smart cities, industrial automation, and environmental monitoring. However, the protocol's vulnerability to various security attacks poses significant threats to the reliability and confidentiality of IoT networks. To address this issue, a novel deep-stacked neuro-fuzzy system (DSNFyS) has been developed for attack detection in RPL-based IoT. The proposed approach begins with simulating RPL routing in IoT, followed by attack detection processing at the Base Station (BS) using log data. Data normalization is accomplished through the application of min-max normalization techniques. The most crucial features are then identified through feature selection, utilizing information gain and Support Vector Machine-Recursive Feature Elimination (SVM-RFE). Attack detection is subsequently performed using DSNFyS, which integrates a Deep Stacked Autoencoder (DSA) with an Adaptive Neuro-Fuzzy Inference System (ANFIS). Upon detection of an attack, mitigation is carried out employing a DSA trained using the Hiking Optimization Algorithm (HOA). The proposed DSNFyS demonstrated exceptional performance, achieving the better accuracy of 97.41%, True Positive Rate (TPR) of 97.60%, and True Negative Rate (TNR) of 97.12%.

Damage Measurement of Collision Attacks on Performance of Wireless Sensor Networks
Статья научная
Wireless sensor networks (WSN) are widely developed to monitor different phenomena in a variety of areas including nature, medical centers, home automation, industrial and military applications. Such development in many different fields, raises important security issues related to the reliability of the WSNs. Due to the resource constrained nature of the WSNs, these networks are the target of many different types of attacks and prone to failure. In this paper, we consider the collision attack. An attempt has been made to measure the impact of the collision attack on the performance of WSNs under variety scenarios performed by the attackers. The main contribution of this paper is to present that although the attack does not consume much energy of the attacker, it can highly disrupt the normal operation of the target sensor networks. The implementation of the proposed attack model has been done by using NS2 network simulator.

Effective storage management is crucial for cloud computing systems' speed and cost, given data's exponential increase. The significance of this issue has increased as the amount of data continues to increase at a disturbing pace. The act of detecting and removing duplicate data can enhance storage utilisation and system efficiency. Using less storage capacity reduces data transmission costs and enhances cloud infrastructure scalability. The use of deduplication techniques on a wide scale, on the other hand, presents a number of important obstacles. Security issues, delays in deduplication, and maintaining data integrity are all examples of difficulties that fall under this classification. This paper introduces a revolutionary method called Data Deduplication-based Efficient Cloud Optimisation Technique (DD-ECOT). Optimising storage processes and enhancing performance in cloud-based systems is its intended goal. DD-ECOT combines advanced pattern recognition with chunking to increase storage efficiency at minimal cost. It protects data during deduplication with secure hash-based indexing. Parallel processing and scalable design decrease latency, making it adaptable enough for vast, ever-changing cloud setups.The DD-ECOT system avoids these problems through employing a secure hash-based indexing method to keep data intact and by using parallel processing to speed up deduplication without impacting system performance. Enterprise cloud storage systems, disaster recovery solutions, and large-scale data management environments are some of the usage cases for DD-ECOT. Analysis of simulations shows that the suggested solution outperforms conventional deduplication techniques in terms of storage efficiency, data retrieval speed, and overall system performance. The findings suggest that DD-ECOT has the ability to improve cloud service delivery while cutting operational costs. A simulation reveals that the proposed DD-ECOT framework outperforms existing deduplication methods. DD-ECOT boosts storage efficiency by 92.8% by reducing duplicate data. It reduces latency by 97.2% using parallel processing and sophisticated deduplication. Additionally, secure hash-based indexing methods improve data integrity to 98.1%. Optimized bandwidth usage of 95.7% makes data transfer efficient. These improvements suggest DD-ECOT may save operational costs, optimize storage, and beat current deduplication methods.

Data Mining Based Hybrid Intelligent System for Medical Application
Статья научная
Hybrid intelligent system is a combination of artificial intelligence (AI) techniques that can be applied in healthcare to solve complex medical problems. Case-based reasoning (CBR) and rule based reasoning (RBR) are the two more popular AI techniques which can be easily combined. Both techniques deal with medical data and domain knowledge in diagnosing patient conditions. This paper proposes a hybrid intelligent system that uses data mining technique as a tool for knowledge acquisition process. Data Mining solves the knowledge acquisition problem of rule based reasoning by supplying extracted knowledge to rule based reasoning system. We use WEKA for model construction and evaluation, Java NetBeans for integrating data mining results with rule based reasoning and Prolog for knowledge representation. To select the best model for disease diagnosis, four experiments were carried out using J48, BFTree, JRIP and PART. The PART classification algorithm is selected as best classification algorithm and the rules generated from the PART classifier are used for the development of knowledge base of hybrid intelligent system. In this study, the proposed system measured an accuracy of 87.5% and usability of 89.2%.

Data Modeling for E-Voting System Using Smart Card based E-Governance System
Статья научная
For a developing country like India, maintaining an efficient administration within affordable budget is a big challenge. The application of Information and Communication Technology (ICT) based E-Governance can facilitate the administration in much efficient and cost effective manner compared to the traditional method of administration. Since an efficient administration is dependent on the collection of opinion of its participants (i.e the voters), flawless voting mechanism becomes the primary pillar of governance. But in the present days of busyness, many people stay away from their voting constituency due to various compulsions, thereby giving rise to number of uncast votes to a significant level. In order to solve this problem, in this paper authors have extended the concept of multifaceted smart card oriented E-Governance system to propose bio-metric authentication based E-Voting system, where Bluetooth fingerprint scanner will be paired with the voter's smart phone to implement the proposed concept. This propose system will use a mobile application to input user identification number using the Multipurpose Electronic Card (MEC) based E-Governance system. In case of successful authentication, the voter will be allowed to caste the original vote, else it will be barred. Hence, this approach will prevent the malicious tendency of proxy voting using advanced authentication system. Since this proposed E-Voting system have to handle huge data traffic during its implementation, its database should be designed at first to reduce data redundancy and inconsistency as much as possible. Hence, in this paper, authors have designed its database system using Data Flow Diagram (DFD), Entity Relationship Diagram (ERD) to demonstrate the relationship between its primary entities and tables.

Deceptive Opinion Detection Using Machine Learning Techniques
Статья научная
Nowadays, online reviews have become a valuable resource for customer decision making before purchasing a product. Research shows that most of the people look at online reviews before purchasing any product. So, customers reviews are now become a crucial part of doing business online. Since review can either promote or demote a product or a service, so buying and selling fake reviews turns into a profitable business for some people now a days. In the past few years, deceptive review detection has attracted significant attention from both the industrial organizations and academic communities. However, the issue remains to be a challenging problem due to the lack of labeled dataset for supervised learning and evaluation. Also, study shows that both the state of the art computational approaches and human readers acquire an error rate of about 35% to 48% in identifying fake reviews. This study thoroughly investigated and analyzed customers’ online reviews for deception detection using different supervised machine learning methods and proposes a machine learning model using stochastic gradient descent algorithm for the detection of spam review. To reduce bias and variance, bagging and boosting approach was integrated into the model. Furthermore, to select the most appropriate features in the feature selection step, some rules using regular expression were also generated. Experiments on hotel review dataset demonstrate the effectiveness of the proposed approach.

Delay Analysis of Network Coded Video Streams in VANETs
Статья научная
Video is a significant medium in data communication through which enormous information could be conveyed in less time. Video Streaming helps us play the streamed data immediately without waiting for the entire file to get downloaded. When the quality of service of video streaming is considered, delay and jitter act as very important parameters, as video streams received late cannot be played and become useless hence wasting the network resources. In Vehicular Adhoc Networks, a special type of Mobile Adhoc Networks, the two possible usages of video streams are in infotainment applications and in the safety applications. In either case, these parameters play a major role. One of the vital techniques that are applied to reduce the delay encountered is Network coding. This paper simulates the transfer of the video streams from one vehicle to another in a group of vehicles in Vehicular Adhoc Networks. Network coding is applied on the video packets here. The routes are established with routing protocols OLSR, AODV and DSDV in the above mentioned scenarios. Node density is varied and these parameters of interest are monitored and analyzed.

Descriptive Modeling Uses K-Means Clustering for Employee Presence Mapping
Статья научная
Human resource is valuable asset for an agency. The success of an institution is not only determined by the quality of its human resources, but also by the level of discipline. The discipline of an employee in an institution can be seen and measured by the level of attendance in doing a job, because the level of attendance is one of the factors that determine productivity. The current problem is the management level of the company that has difficulty in monitoring and controlling the employee attendance data. There needs to be a mapping and grouping to find out patterns of absence. Mapping or patterns that are obtained help management levels to monitor employees, take approaches and take action so as to improve employee discipline. In this study, it was used descriptive modeling with the implementation of the k-means clustering method. The results of the mapping obtained help the management level in controlling and monitoring as a reference for the next policy maker.

Computed torque controller (CTC) is a significant nonlinear controller under condition of partly uncertain dynamic parameters of system. This controller is used to control of highly nonlinear systems especially for robot manipulators, because this controller is a robust and stable. Conversely, computed torque controller is used in many applications; it has an important drawback namely; nonlinear equivalent dynamic formulation in uncertain dynamic parameter. The nonlinear equivalent dynamic formulation problem in uncertain system can be solved by using artificial intelligence theorem. However fuzzy logic controller is used to control complicated nonlinear dynamic systems, but it cannot guarantee stability and robustness. In this research parallel fuzzy logic theory is used to compensate the system dynamic uncertainty in computed torque controller.

Статья научная
The increasing demand for multi-degree-of-freedom (DOF) continuum robot in presence of highly nonlinear dynamic parameters in a number of industries has motivated a flurry of research in the development of soft computing nonlinear methodology. This research contributes to the on-going research effort by exploring alternate methods for controlling the continuum robot manipulator. This research addresses two basic issues related to the control of a continuum robots; (1) a more accurate representation of the dynamic model of an existing prototype, and (2) the design of a robust feedback controller. The robust back stepping controller proposed in this research is used to further demonstrate the appealing features exhibited by the continuum robot. Robust feedback controller is used to position control of continuum robot in presence of uncertainties. Using Lyapunov type stability arguments, a robust back stepping controller is designed to achieve this objective. The controller developed in this research is designed into two steps. Firstly, a robust stabilizing torque is designed for the nominal continuum robot dynamics derived using the constrained Lagrangian formulation. Next, the fuzzy logic methodology applied to it to solution uncertainty problem. The fuzzy model free problem is formulated to minimize the nonlinear formulation of continuum robot. The eventual stability of the controller depends on the torque generating capabilities of the continuum robots.

Статья научная
The minimum rule base Proportional Integral Derivative (PID) Fuzzy backstepping Controller for three dimensions spherical motor is presented in this research. The popularity of PID Fuzzy backstepping controller can be attributed to their robust performance in a wide range of operating conditions and partly to their functional simplicity. The process of setting of PID Fuzzy backstepping controller can be determined as an optimization task. Over the years, use of intelligent strategies for tuning of these controllers has been growing. PID methodology has three inputs and if any input is described with seven linguistic values, and any rule has three conditions we will need 7 × 7 × 7 = 343 rules. It is too much work to write 343 rules. In this research the PID-like fuzzy controller can be constructed as a parallel structure of a PI-like controller and a PD-like fuzzy controller to have the minimum rule base. However backstepping controller is work based on cancelling decoupling and nonlinear terms of dynamic parameters of each dimension, this controller is work based on spherical motor dynamic model and this technique is highly sensitive to the knowledge of all parameters of nonlinear three dimension spherical motor’s dynamic equation. This research is used to reduce or eliminate the backstepping controller problem based on minimum rule base fuzzy logic theory to control of spherical motor system and testing of the quality of process control in the simulation environment of MATLAB/SIMULINK Simulator.
