Urban RIS-Assisted HAP Networks: Performance Analysis Using Stochastic Geometry
Islam M. Tanash, Ayush Kumar Dwivedi, Taneli Riihonen
This paper studies a high-altitude platform (HAP) network supported by reconfigurable intelligent surfaces (RISs). The practical irregular placement of HAPs and RISs is modeled usi…
Enhancing HAP Networks with Reconfigurable Intelligent Surfaces
Islam M. Tanash, Ayush Kumar Dwivedi, Fatemeh Rafiei Maleki +1
This paper presents and analyzes a reconfigurable intelligent surface (RIS)-based high-altitude platform (HAP) network. Stochastic geometry is used to model the arbitrary locations…
Efficient Transmission Scheme for LEO Satellite-Based NB-IoT: A Data-Driven Perspective
Ayush Kumar Dwivedi, Houcine Chougrani, Sachin Chaudhari +2
This study analyses the medium access control (MAC) layer aspects of a low-Earth-orbit (LEO) satellite-based Internet of Things (IoT) network. A transmission scheme based on change…
Development of End-to-End Low-Cost IoT System for Densely Deployed PM Monitoring Network: An Indian Case Study
Ayu Parmar, Spanddhana Sara, Ayush Kumar Dwivedi +6
Particulate matter (PM) is considered the primary contributor to air pollution and has severe implications for general health. PM concentration has high spatial variability and thu…
Performance Analysis of LEO Satellite-Based IoT Networks in the Presence of Interference
Ayush Kumar Dwivedi, Sachin Chaudhari, Neeraj Varshney +1
This paper presents a star-of-star topology for internet-of-things (IoT) networks using mega low-Earth-orbit constellations. The proposed topology enables IoT users to broadcast th…
