Cooperative Localization Using Received Signal Strength and Least Squares Estimation Methods

December 6, 2023

Author(s)

Nader Moayeri

In this paper we use two Recursive Least Squares (RLS) estimation methods to solve the cooperative localization problem based on Wi-Fi received signal strength measurements between pairs of nodes in a network that can establish communication links. A link

On the Feasibility of COVID-19 Proximity Detection Using Bluetooth Low Energy Signals

November 29, 2022

Author(s)

Nader Moayeri, Chang Li, Lu Shi

The COrona VIrus Disease – 2019 (COVID-19) pandemic has had a profound effect on the entire world. With the onset of the pandemic in 2020, also started various efforts around the world to automate the contact tracing process to increase its efficacy. Most

On the Use of Lookahead to Improve Wi-Fi Fingerprinting Indoor Localization Accuracy

November 29, 2021

Author(s)

Lu Shi, Nader Moayeri, Chang Li

Causality is a basic concept in system theory. In this paper we introduce the notions of causal and non-causal indoor localization. A non-causal localization system uses future signal and sensor measurements, in addition to past and present ones, to

Response to "Evaluation of Indoor Localisation Systems: Comments on the ISO/IEC 18305 Standard"

November 29, 2021

Author(s)

Nader Moayeri

Potorti et. al. wrote a paper [1] that was dubbed as the first critical reading of the international standard ISO/IEC 18305 [2], Test and evaluation of localization and tracking systems. The author of this paper served as the Editor of ISO/IEC 18305. As

Indoor Localization Accuracy of Major Smartphone Location Apps

April 14, 2019

Author(s)

Nader Moayeri, Chang Li, Lu Shi

NIST carried out comprehensive testing in five large buildings to evaluate the accuracy of Fused Location Provider (FLP) Application Programming Interface (API) running on Android phones with that of Core Location Framework running on iPhones. The testing

Frame-Based Randomized Scheduling of Packets with Random-Deadlines for Multi-Flow Wireless Networks

March 15, 2019

Author(s)

Mohamed T. Hany, Nader Moayeri

The use of wireless communications in industrial applications has motivated various advances in manufacturing automation by allowing more flexibility in installing wireless sensors and actuators than their wired counterparts. The main challenge in

2018 Stakeholder Meeting Presentations, Day 3, Room 30A

PerfLoc (Part 2): Performance Evaluation of the Smartphone Indoor Localization Apps

September 23, 2018

Author(s)

Nader Moayeri, Chang Li, Lu Shi

This paper describes the structure of the PerfLoc Prize Competition organized by the US National Institute of Standards and Technology (NIST). The Competition consisted of collecting an extensive repository of smartphone data, releasing the data to

Random-Deadline Missing Probability Analysis for Wireless Communications in Industrial Environments

July 5, 2018

Author(s)

Mohamed T. Hany, Nader Moayeri

The flexibility of wireless networks, and their cost-efficient setup and maintenance have motivated the deployment of wireless communications in industrial environments. Strict industrial requirements including the time-sensitive delivery of data have led

Employing Cyber-Physical Systems: Dynamic Traffic Light Control at Road Intersections

December 1, 2017

Author(s)

Ossama M. Younis, Nader Moayeri

Traffic Lights are used to control traffic at road intersections. Typically, the employed traffic light control mechanism on the road operates according to a periodic schedule to change the light/color (red/yellow/green). In some places, a different

Wireless Activities in the 2 GHz Radio Bands in Industrial Plants

September 27, 2017

Author(s)

Yongkang Liu, Nader Moayeri

Wireless connections are becoming popular in industrial environments that increasingly carry sensing and actuation data over the air. In industrial plants, activities of legacy wireless systems have shaped the channel usage in the radio spectrum bands for

Real-Time Scheduling for Wireless Networks with Random Deadlines

July 26, 2017

Author(s)

Mohamed Hany, Nader Moayeri

The use of wireless communications in industrial environments is motivated by the flexibility that wireless networks provide and their cost-efficient setup and maintenance. Various wireless technologies have been introduced to satisfy the strict industrial

Channel Modeling and Performance of Zigbee Radios in an Industrial Environment

May 31, 2017

Author(s)

Mehrdad Damsaz, Derek Guo, Jeff Peil, Wayne Stark, Nader Moayeri, Rick Candell

In this paper we describe measurements of wireless propagation characteristics to develop path loss models in industrial environments. The models for path loss we develop are two-slope models in which the path loss is a piecewise linear relation with the
