Summary
Location-aware handover (LHO) in wireless heterogeneous networks (HetNets) improves throughput and link robustness. Combining geometry-based positioning with dead reckoning enhances accuracy for autonomous systems.
Area of Science:
- Wireless communication systems
- Robotics and autonomous systems
- Signal processing and positioning
Background:
- Future wireless heterogeneous networks (HetNets) integrate millimeter wave (mmWave) and low-frequency interfaces.
- Unifying communication and positioning technologies offers potential for location-aware handover (LHO).
- Autonomous vehicles in self-organized communication systems benefit from efficient handover mechanisms.
Purpose of the Study:
- To experimentally and analytically study location-aware handover (LHO) in a mmWave-enabled robotic platform within a multi-radio environment.
- To propose and evaluate a geometry-based positioning (GBP) algorithm for location awareness.
- To compare LHO performance against conventional received signal strength indicator (RSSI)-based handover.
Main Methods:
- Implementation and testing of a geometry-based positioning (GBP) algorithm in simulation and experiments.
- Experimental study using a mmWave-enabled robotic platform in a multi-radio environment.
- Combination of GBP with dead reckoning for enhanced location accuracy.
Main Results:
- Standalone GBP algorithm showed insufficient accuracy for reliable handover based on robot-acquired measurements.
- Combining GBP with dead reckoning significantly improved location awareness accuracy.
- Location-aware handover demonstrated improved achievable throughput and wireless link robustness for Industrial Internet-of-Things (IIoT) applications.
- The proposed LHO scheme achieved approximately twice the average throughput in certain scenarios compared to RSSI-based handover.
Conclusions:
- Accurate location awareness is crucial for enabling efficient handover schemes in HetNets.
- The integration of GBP and dead reckoning provides a viable method for achieving the necessary location accuracy for LHO.
- Location-aware handover enhances autonomous features and performance in future wireless networks, particularly for IIoT applications.

01:24The Midpoint Formula
477
In coordinate geometry, determining the central point between two locations is common. This central point, or midpoint, lies exactly halfway along the line segment connecting two points in a two-dimensional space. It has applications in mathematics, physics, engineering, and various planning disciplines.Given two points labeled as A (x1, y1) and B (x2, y2) on a coordinate plane, a straight line segment can be plotted between them. The midpoint, labeled point M, divides this segment into two...

01:21Distributed Loads: Problem Solving
953
Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

17.1K
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.

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
