Field Application of Global Positioning System01:28

Field Application of Global Positioning System

343
The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...

Types of Global Positioning System Surveys

406
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...

Errors in Global Positioning System

380
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Introduction to Global Positioning System

653
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Short-distance Transport of Resources02:12

Short-distance Transport of Resources

17.9K
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.

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

434
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Area of Science:

  • Computer Science
  • Network Security
  • Wireless Sensor Networks

Background:

  • Existing secure geographic routing protocols for Wireless Sensor Networks (WSNs) suffer from issues like packet drops due to failed legitimate node responses and inadequate attacker identification.
  • Inefficient collection windows and insufficient verification criteria in current protocols lead to frequent attacker selections and packet retransmissions.

Purpose of the Study:

  • To propose a Secure Region-Based Geographic Routing Protocol (SRBGR) that enhances the probability of selecting appropriate relay nodes in WSNs.
  • To address the limitations of existing protocols by improving the routing initiation process and attacker isolation.

Main Methods:

  • The proposed SRBGR protocol extends the allocated sextant and introduces message contention priorities to include more legitimate nodes in routing.
  • It implements a bound collection window for adequate collection time and a verification cost mechanism for identifying and isolating attackers.

Main Results:

  • Extensive simulations show SRBGR outperforms existing protocols in packet delivery ratio.
  • The protocol effectively isolates Sybil and Black hole attacks in Wireless Sensor Networks.

Conclusions:

  • SRBGR significantly improves the performance and security of geographic routing in WSNs.
  • The protocol offers a robust solution against common network attacks, ensuring reliable data transmission.
