Coverage Analysis of Reconfigurable Intelligent Surface Assisted THz Wireless Systems
IEEE Open Journal of Vehicular Technology, 2021 This paper presents a connectivity analysis of reconfigurable intelligent surface (RIS) assisted terahertz (THz) wireless systems. Specifically, a system model that accommodates the particularities of THz band links as well as the characteristics of the ...

Coverage Analysis for UAV-Assisted Cellular Networks in Rural Areas
IEEE Open Journal of Vehicular Technology, 2021 Despite enhancement in rural areas is one of the main requirements in next generations of wireless networks (i.e., 5G and 6G), the low expected profit prevents telecommunication providers from investing in such sparsely populated areas.

Coverage Probability Analysis of UAV Cellular Networks in Urban Environments [PDF]
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018 In this paper, we study coverage probabilities of the UAV-assisted cellular network modeled by 2-dimension (2D) Poisson point process. The cellular user is assumed to connect to the nearest aerial base station.

Coverage probability of uplink cellular networks [PDF]
2012 IEEE Global Communications Conference (GLOBECOM), 2012 The cellular uplink has typically been studied using simple Wyner-type analytical models where interference is modeled as a constant or a single random variable, or via complex system-level simulations for a given set of parameters, which are often insufficient to evaluate performance in all operational regimes.
