Improved dsr algo routing in manet
This document summarizes a research paper on designing an energy routing protocol called EPAR to optimize power consumption in mobile ad hoc networks (MANETs). EPAR aims to minimize total transmission energy and maximize network lifetime. It calculates the battery power for each path and selects the path with the maximum lowest hop energy. Simulation results show that EPAR outperforms the original DSR protocol by 65% and achieves higher throughput than DSR and another protocol called MTPR in different network scenarios. EPAR and MTPR also produce longer network lifetimes than DSR when considering factors like packet delivery ratio.
DSR Protocol
The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed for use in wireless ad-hoc networks without existing infrastructure. DSR allows networks to self-organize and self-configure. It uses two main mechanisms: route discovery determines the optimal transmission path between nodes, while route maintenance ensures the path stays optimal and loop-free as network conditions change.
DYNAMIC SOURCE ROUTING (DSR)
Dynamic Source Routing uses route discovery to find routes between nodes. When a node receives a route request (RREQ) message, if it is the destination it returns a route reply (RREP) with the accumulated route record to the sender. If it is an intermediate node, it discards the RREQ if it has the same ID or finds its own address in the route, otherwise it appends its address to the route record and propagates the RREQ to neighbors to continue finding a path to the destination.
Dynamic source routing
DSR is a source routing protocol for wireless ad hoc networks. It uses source routing whereby the source specifies the complete path to the destination in the packet header. Route discovery is done through route request broadcasts, and routes are cached for future use. Route maintenance is done through acknowledgements; if a link breaks, a route error is sent back to the source. Simulation results showed high packet delivery ratios even with high node mobility. DSR performs well for dynamic wireless networks.
Database security
Database security involves protecting a database from unauthorized access, modification, or deletion. It aims to ensure the confidentiality, integrity, and availability of data through various mechanisms like access controls, encryption, firewalls, and authorization levels. These controls regulate how data flows between systems and users, prevent indirect data inferences, and restrict access to only authorized users and operations. The goal is to safeguard sensitive information in databases from both intentional and accidental security threats.
Vulnerabilities in Android
The document discusses vulnerabilities in the Android operating system. It begins by noting the dominance of Android and iOS in the smartphone market and the need for privacy awareness as malicious codes are increasingly reported. It then defines vulnerability as a weakness or soft spot, and lists some common types of vulnerabilities like invalidated inputs, broken access control, and SQL injection. The document also covers Android security features like encryption, sandboxing, and permissions, as well as current issues around mobile security including malicious apps, unsafe websites, and data security problems. It concludes that while Android utilizes sandboxing and permissions, optional permission assignments can still leave security loopholes.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
