Summary
This study introduces an efficient location service for mobile sinks in solar-powered wireless sensor networks (WSNs). It uses surplus energy to reduce overhead, extending network life in challenging environments.
Area of Science:
- Computer Science
- Electrical Engineering
- Network Engineering
Background:
- Wireless Sensor Networks (WSNs) enable deployment in isolated or dangerous environments.
- Mobile sinks in WSNs improve energy balance and network lifetime but incur location overhead.
- Solar-powered WSNs are studied for perpetual network operation.
Purpose of the Study:
- To propose an efficient location service for mobile sinks in solar-powered WSNs.
- To address the challenges of location overhead and energy consumption in WSNs.
- To leverage surplus energy from solar-powered nodes for location services.
Main Methods:
- Nodes with surplus energy form 'rings' to maintain mobile sink location.
- These 'ring nodes' provide location information to other sensor nodes.
- The scheme supports multiple simultaneous rings to reduce location acquisition overhead.
Main Results:
- Location service utilizes surplus energy without impacting general node operations.
- Overhead for acquiring mobile sink position is significantly reduced.
- The overhead increase is minimal even with larger network sizes.
Conclusions:
- The proposed method efficiently supports mobile sink location services in solar-powered WSNs.
- It effectively balances energy consumption and prolongs network lifetime.
- This approach is scalable and minimizes overhead in large-scale WSN deployments.

4.5K
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,...

9.5K
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

16.2K
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...

01:13Location and Orientation of the Heart
10.1K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
