Background:
- Vehicular ad hoc networks (VANETs) present unique challenges for standard routing protocols due to high vehicle density and rapid network changes.
- Frequent link breakages in VANETs necessitate robust routing consistency.
- High routing overhead in VANETs negatively impacts overall network performance.
Purpose of the Study:
- To propose a novel routing protocol, Compacted Area with Effective Links (CAEL), to decrease routing overhead in VANETs.
- To enhance Packet Delivery Ratio (PDR) performance within VANETs by minimizing overhead.
- To improve the efficiency and reliability of VANET communication.
Main Methods:
- Developed the Compacted Area with Effective Links (CAEL) protocol.
- Focused communication on selected dependable nodes with appropriate existing links.
- Incorporated a reliability factor based on link expiration time to remove extraneous nodes and select trustworthy nodes.
Main Results:
- The CAEL protocol effectively reduces routing overhead in VANETs.
- Simulation results demonstrate a significant enhancement in Packet Delivery Ratio (PDR) performance.
- CAEL outperforms previously published protocols like Dynamic Trilateral Enrollment (DyTE) and Reliable Group of Vehicles (RGoV).
Conclusions:
- CAEL offers an improved approach to routing in dynamic VANET environments.
- The protocol's focus on reliable nodes and link expiration time enhances network efficiency.

66.9K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...

Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

The compacting factor test is a method used to assess the workability of concrete. It is especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

16.5K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...
