Pedestrian Dead Reckoning System with Phone Location Awareness Algorithm

, 2010
In this paper we present a PDR (Pedestrian Dead Reckoning) system with a phone location awareness algorithm. PDR is a device which provides position information of the pedestrian. In general, the step length is estimated using a linear combination of the

A Systematic Review of VANET Routing Protocols for Intelligent Transport Systems (ITSs)

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The swift improvement of wireless communication technology has aided the creation of vehicular ad hoc networks (VANETs) as a revolutionary option for the realization of intelligent transportation systems (ITSs). VANETs facilitate seamless communication between vehicles and infrastructure (V2I) and among the vehicles themselves (V2V). These networks can

WiFi/PDR-integrated indoor localization using unconstrained smartphones

EURASIP Journal on Wireless Communications and Networking, 2019
In this paper, we propose a WiFi/pedestrian dead reckoning (PDR)-integrated localization approach based on unscented Kalman filters (UKF). The UKF integrating WiFi localization with PDR is used for ultimate location estimation. Instead of setting process

Biofilm Formation in Clinical Acinetobacter baumannii Is Influenced by Isolate Source and Is Inversely Correlated With Antibiotic Resistance

BioMed Research International, Volume 2026, Issue 1, 2026.
Acinetobacter baumannii is a troublesome bacterium that is highly prevalent in hospital settings, particularly in intensive care units (ICUs). Biofilm is one of the main virulence factors that makes A. baumannii a successful pathogen, enabling it to survive the harshest environments.

A Depth‐Ordered Forwarding Game With Niche‐Confined Evolutionary Recovery for Energy‐Efficient Underwater Wireless Sensor Networks

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Underwater wireless sensor networks operate under scarce acoustic bandwidth, long propagation delay, depth‐dependent attenuation, and a fixed energy budget that is rarely replenished. We propose the Hawk–Dove Game Optimization Algorithm with Elite Niche Clone Evolutionary Computing (HDGOA‐ENCEC), a routing protocol that couples a depth‐ordered ...

Network‐Controlled Repeaters and Deep Q‐Learning for Energy‐Efficient 6G Routing: A Lifelike Simulation Framework Using GNS3

Journal of Engineering, Volume 2026, Issue 1, 2026.
In the forthcoming 6G era, network infrastructure must achieve unprecedented energy efficiency, adaptability, and ultralow latency. This paper proposes a novel Deep Q‐Network (DQN)‐based routing framework that leverages network‐controlled repeaters (NCRs) to optimize routing paths dynamically.

Vehicular‐to‐Everything (V2X) Communication Using 5G NR for Autonomous Vehicles

Journal of Engineering, Volume 2026, Issue 1, 2026.
This paper explores the fundamental issue to conflicting performance requirements in 5G New Radio (5G NR) vehicle‐to‐everything (V2X) communications for autonomous driving applications. Unlike the previous literature where most of its studies consider single performance measures in a fixed or simplified environment, the proposed system presents a ...

Demand Response Control Framework for Electric Water Heaters Enabling Primary and Secondary Frequency Regulation

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
In modern power systems, increasing flexibility has become an essential aspect of supporting the integration of renewable energy resources (RERs). The rapid fluctuations in power output from RERs and the reduced reliance on conventional thermal units necessitate flexible energy resources and demand‐side solutions.
