IEEE 802.11bf: Enabling the Widespread Adoption of Wi-Fi Sensing

May 31, 2023
Author(s)
Tanguy Ropitault, Steve Blandino, Anirudha Sahoo, Nada T. Golmie
In recent years, Wi-Fi has been shown to be a viable technology to enable a wide range of sensing applications, and Wi-Fi sensing has become an active area of research and development. Due to the significant and growing interest in Wi-Fi sensing, Task

IEEE 802.11bf DMG Sensing: Enabling High-Resolution mmWave Wi-Fi Sensing

January 16, 2023
Author(s)
Steve Blandino, Tanguy Ropitault, Anirudha Sahoo, Nada T. Golmie
IEEE 802.11bf amendment is defining the Wireless Local Area Network (WLAN) sensing procedure, which supports sensing in license-exempt frequency bands below 7 GHz and above 40GHz. In this paper, we examine WLAN sensing in the millimeter wave band, i.e.,

Admission Control and Scheduling of Isochronous Traffic in IEEE 802.11ad MAC

December 20, 2021
Author(s)
Anirudha Sahoo, Weichao Gao, Tanguy Ropitault, Nada T. Golmie
An upsurge of bandwidth hungry applications such as virtual reality, augmented reality and availability of unlicensed spectrum in the mmWave band at 60 GHz have led to standardization of the next generation WiFi such as IEEE 802.11ad and 802.11ay. Due to

Tools, Models and Dataset for IEEE 802.11ay CSI-based Sensing

September 10, 2021
Author(s)
Steve Blandino, Tanguy Ropitault, Anirudha Sahoo, Nada T. Golmie
The ubiquitous deployment and availability of wireless communication devices create the perfect opportunity to provide new wireless local area network (WLAN) use-cases, by implementing new sensing capabilities, while leveraging existing communications

A Machine Learning Based Scheme for Dynamic Spectrum Access

March 30, 2021
Author(s)
Anirudha Sahoo
In this paper, we present a machine learning (ML) based dynamic spectrum access (DSA) scheme which can be used in a system in which primary user (PU) spectrum occupancy can be represented as a sequence of busy (on) and idle (off) periods. We use real world

GAA-GAA Coexistence in the CBRS Band: Performance Evaluation of Approach 3

November 19, 2020
Author(s)
Anirudha Sahoo, Weichao Gao
The General Authorized Access (GAA) users operate at the lowest priority in the Citizens Broadband Radio Service (CBRS) band. So they must not cause harmful interference to the higher priority users. In addition, the GAA users must cooperate with each

Performance Study of a GAA-GAA Coexistence Scheme in the CBRS Band

December 19, 2019
Author(s)
Weichao Gao, Anirudha Sahoo
The General Authorized Access (GAA) users in the Citizens Broadband Radio Service (CBRS) band are the lowest priority users who not only have to make sure that they do not cause harmful interference to the higher tier users but also must cooperate with

Optimal Dynamic Spectrum Access Scheme for Utilizing White Space in LTE Systems

April 15, 2019
Author(s)
Anirudha Sahoo, Timothy Hall, Robert C. Hagwood
In this study, we design and implement an algorithm for optimal dynamic spectrum access (DSA) in a shared spectrum system where the primary user (PU) is a Long Term Evolution (LTE) system. The cumulative hazard function from survival analysis is used to

Dynamic Spectrum Access Algorithms Based on Survival Analysis

December 20, 2017
Author(s)
Timothy Hall, Anirudha Sahoo, Robert C. Hagwood, Sarah B. Streett
In this study, we design and implement two algorithms for dynamic spectrum access (DSA) that are based on survival analysis. They use a non-parametric estimate of the cumulative hazard function to predict the remaining idle time available for secondary

3.5 GHz Environmental Sensing Capability Detection Thresholds and Deployment

September 1, 2017
Author(s)
Thao Nguyen, Anirudha Sahoo, Michael R. Souryal, Timothy Hall
Spectrum sharing in the 3.5~GHz band between commercial and government users along U.S. coastal areas depends on an Environmental Sensing Capability (ESC)---that is, a network of radio frequency sensors and a decision system---to detect the presence of

Fair Resource Allocation in the Citizen Broadband Radio Service Band

March 6, 2017
Author(s)
Anirudha Sahoo
The Citizen Broadband Radio Service (CBRS) band has three tiers of users. The General Authorized Access (GAA) has the lowest priority and operates without a license. A Spectrum Access System (SAS) is responsible for managing spectrum among the users. The

3.5 GHz Environmental Sensing Capability Sensitivity Requirements and Deployment

March 5, 2017
Author(s)
Thao T. Nguyen, Anirudha Sahoo, Michael R. Souryal, Timothy Hall
Spectrum sharing in the 3.5 GHz band between commercial and government users along U.S. coastal areas depends on an Environmental Sensing Capability (ESC), a network of radio frequency sensors and a decision system, to detect the presence of incumbent

Dynamic Spectrum Access: Current State of the Art and Future Challenges

February 2, 2014
