Summary
A new Trust-Based Secure Routing (TBSR) scheme enhances security and energy efficiency in Internet of Things (IoT) networks. This approach uses disjoint paths and dynamic probability for marking and logging to effectively trace and remove malicious nodes, improving data routing success rates.
Area of Science:
- Computer Science
- Network Security
- Wireless Sensor Networks
Background:
- The Internet of Things (IoT) faces significant security threats due to its reliance on communication technologies.
- Energy-Harvesting Wireless Sensor Networks (EHWSNs) require robust security mechanisms that also optimize energy consumption.
Purpose of the Study:
- To propose a Trust-Based Secure Routing (TBSR) scheme for EHWSNs to enhance data routing security and energy efficiency.
- To improve the reliability of data transmission by effectively identifying and mitigating malicious nodes within the network.
Main Methods:
- Implemented a TBSR scheme where data and notification packets travel through disjoint paths for independent verification.
- Utilized a dynamic probability approach for marking and logging based on remaining battery levels to balance security and energy conservation.
- Employed a traceback mechanism to locate and clear malicious nodes when network attacks are detected.
Main Results:
- The TBSR scheme increased the quantity of notifications received by the sink by 20%.
- Achieved an 11% increase in energy efficiency and a 16.30% improvement in the success rate of routing.
- Reduced the maximum storage capacity needed by nodes by 33.3%.
Conclusions:
- The TBSR scheme offers a comprehensive improvement in performance for EHWSNs compared to existing solutions.
- The dynamic probability adjustment effectively conserves energy while maintaining high network security and routing efficiency.

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

The light reactions of photosynthesis assume a linear flow of electrons from water to NADP+. During this process, light energy drives the splitting of water molecules to produce oxygen. However, oxidation of water molecules is a thermodynamically unfavorable reaction and requires a strong oxidizing agent. This is accomplished by the first product of light reactions: oxidized P680 (or P680+), the most powerful oxidizing agent known in biology. The oxidized P680 that acquires an electron from the...

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

The universe is composed of matter in different forms, and all forms of matter contain energy. The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
