Age of Information with On-Off Service
Ashirwad Sinha, Praful D. Mankar, Nikolaos Pappas +1
This paper considers a communication system where a source sends time-sensitive information to its destination. We assume that both arrival and service processes of the messages ar…
Optimal Beamforming and Outage Analysis for Max Mean SNR under RIS-aided Communication
Kali Krishna Kota, Praful D. Mankar, Harpreet S. Dhillon
This paper considers beamforming for a reconfigurable intelligent surface (RIS)-aided multiple input single output (MISO) communication system in the presence of Rician multipath f…
Matern Cluster Process with Holes at the Cluster Centers
Seyed Mohammad Azimi-Abarghouyi, Harpreet S. Dhillon
Inspired by recent applications of point processes to biological nanonetworks, this paper presents a novel variant of a Matérn cluster process (MCP) in which the points located wit…
Robust Optimization of RIS in Terahertz under Extreme Molecular Re-radiation Manifestations
Anish Pradhan, Mohamed A. Abd-Elmagid, Harpreet S. Dhillon +1
Terahertz (THz) communication signals are susceptible to severe degradation because of the molecular interaction with the atmosphere in the form of subsequent absorption and re-rad…
RIS-Aided Localization under Position and Orientation Offsets in the Near and Far Field
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
This paper presents a rigorous Bayesian analysis of the information in the signal (consisting of both the line-of-sight (LOS) path and reflections from multiple reconfigurable inte…
Modeling of Dense CSMA Networks using Random Sequential Adsorption Process
Priyabrata Parida, Harpreet S. Dhillon
We model a dense wireless local area network where the access points (APs) employ carrier sense multiple access (CSMA)-type medium access control protocol. In our model, the spatia…
Fundamentals of Clustered Molecular Nanonetworks
Seyed Mohammad Azimi-Abarghouyi, Harpreet S. Dhillon, Leandros Tassiulas
We present a comprehensive approach to the modeling, performance analysis, and design of clustered molecular nanonetworks in which nano-machines of different clusters release an ap…
Beyond Transmitting Bits: Context, Semantics, and Task-Oriented Communications
Deniz Gunduz, Zhijin Qin, Inaki Estella Aguerri +5
Communication systems to date primarily aim at reliably communicating bit sequences. Such an approach provides efficient engineering designs that are agnostic to the meanings of th…
Fundamentals of Vehicular Communication Networks with Vehicle Platoons
Kaushlendra Pandey, Kanaka Raju Perumalla, Abhishek K. Gupta +1
Vehicular platooning is a promising way to facilitate efficient movement of vehicles with a shared route. Despite its relevance, the interplay of platooning and the communication p…
Fundamentals of RIS-Aided Localization in the Far-Field
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
This paper develops fundamental bounds for localization in orthogonal frequency division multiplexing (OFDM) systems aided by reconfigurable intelligent surfaces (RISs). Specifical…
Fundamentals of Wobbling and Hardware Impairments-Aware Air-to-Ground Channel Model
Morteza Banagar, Harpreet S. Dhillon
In this paper, we develop an impairments-aware air-to-ground unified channel model that incorporates the effect of both wobbling and hardware impairments, where the former is cause…
Joint Distribution of Ages of Information in Networks
Mohamed A. Abd-Elmagid, Harpreet S. Dhillon
We study a general setting of status updating systems in which a set of source nodes provide status updates about some physical process(es) to a set of monitors. The freshness of i…
Multilayer Random Sequential Adsorption
Priyabrata Parida, Harpreet S. Dhillon
In this work, we present a variant of the multilayer random sequential adsorption (RSA) process that is inspired by orthogonal resource sharing in wireless communication networks.…
