Summary
This study introduces a region-based beaconless geographic routing protocol to prevent duplicate data packets and improve forwarding in irregular sensor networks. The new method enhances packet delivery and reduces delays compared to existing protocols.
Area of Science:
- Computer Science
- Wireless Sensor Networks
- Network Routing Protocols
Background:
- Beaconless geographic routing protocols are popular for location exchange without beacons.
- Existing protocols suffer from duplicate packets and are unsuitable for irregular sensor fields with voids.
- Forwarding failures and packet duplication hinder performance in random sensor networks.
Purpose of the Study:
- To propose a region-based collision avoidance beaconless geographic routing protocol.
- To enhance forwarding opportunities and prevent packet duplication in randomly-deployed sensor networks.
- To address limitations of existing protocols in irregular sensor fields.
Main Methods:
- A region-based collision avoidance strategy is introduced.
- Contention priorities are assigned to nodes within the greedy area.
- Utilizes mutually-communicable nodes and other neighbors for data forwarding.
Main Results:
- Eliminates packet duplication by enabling all neighbor nodes in the greedy area to forward data.
- Increases the packet delivery ratio.
- Shortens the end-to-end delay.
- Demonstrates improved performance over comparative protocols.
Conclusions:
- The proposed protocol effectively prevents packet duplication and forwarding failures in irregular sensor fields.
- It enhances the efficiency of beaconless geographic routing in wireless sensor networks.
- Offers a viable solution for practical, real-world sensor network deployments.

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...

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...

01:21Chemotaxis and Direction of Cell Migration
6.2K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...
