Summary
This study introduces a novel routing protocol for vehicular ad hoc networks (VANETs) using four metrics to enhance data delivery. The new protocol significantly improves packet delivery rates in dynamic network conditions.
Area of Science:
- Computer Science
- Network Engineering
Background:
- Vehicular ad hoc networks (VANETs) face routing challenges due to their dynamic nature.
- Existing routing protocols often struggle with high packet loss and delay.
Purpose of the Study:
- To propose a new routing protocol for VANETs that optimizes forwarding decisions.
- To minimize packet losses and delay by utilizing vehicle sensor data.
Main Methods:
- Developed a novel routing protocol incorporating distance to destination, vehicle density, trajectory, and available bandwidth.
- Compared the proposed protocol against AODV, GPSR, I-GPSR, and GBSR-B through simulations.
- Evaluated the individual impact of each metric on forwarding decisions.
Main Results:
- The proposed routing protocol demonstrated superior performance in terms of packet delivery ratio compared to existing solutions.
- Simulation results validated the effectiveness of the multi-metric approach.
Conclusions:
- The novel routing protocol offers a significant improvement for VANETs.
- Utilizing multiple metrics enhances routing efficiency and reliability in dynamic vehicular environments.

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

14.5K
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.

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

The transport number is the fraction of the total current carried by an ion in an electrolyte solution. It is defined as the ratio of the current carried by a specific ion to the total current flowing through the solution. The transport number, t, is central to understanding ionic mobility, which describes how fast an ion moves under the influence of an electric field. This link connects the physical behavior of ions in solution to the chemical processes that occur during electrochemical...

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
