Interference Management in Heterogeneous Cellular Networks
… analytically investigated, first based on the Poisson point process (PPP) model where the locations of BSs in each tier are modeled as a PPP. Second, a hybrid model of HetNets is established which considers both location regularity of macro BSs and topological randomness of small BSs, where the …

Performance Analysis for 5G cellular networks: Millimeter Wave and UAV Assisted Communications
… (ASEP) in mmWave cellular networks with Poisson Point Process (PPP) distributed BSs is conducted using tools from stochastic geometry. Secondly, we analyze the energy efficiency of relay-assisted downlink mmWave cellular networks. Then, we provide an stochastic geometry framework to study …

Cellular-Assisted Vehicular Communications: A Stochastic Geometric Approach
… models, most of it uses homogeneous planar Poisson Point Process (PPP) to maintain tractability, which is clearly not applicable to VANETs. Therefore, to accurately capture the spatial distribution of vehicles in a VANET, we model the roads using the so called Poisson Line Process and then …

Enhancing Performance of Next-Generation Vehicular and Spectrum Sharing Wireless Networks: Practical Algorithms and Fundamental Limits
… and (b) leveraging advanced spatial signal processing techniques using large antenna arrays (termed as massive MIMO). In this dissertation, we focus on enhancing the performance of next-generation vehicular communication and spectrum sharing systems. In the first contribution, we present a …

Ambient Backscatter Communication Systems: Design, Signal Detection and Bit Error Rate Analysis
… provided both from analytical and numerical standpoints. Second, the highly appealing non-coherent signal detection is explored in the context of ambient backscatter for a time-selective channel. Modeling the time-selective fading as a first-order autoregressive (AR) process, we implement a new …

Stochastic Geometry for Vehicular Networks
… the canonical spatial models such as the 2D Poisson point process (PPP) does not capture the peculiar spatial layout of vehicular networks, where the locations of vehicular nodes are restricted to roadways. Motivated by this, we consider a doubly stochastic spatial model that captures the …

Statistical Analysis of Geolocation Fundamentals Using Stochastic Geometry
… and potential target positions can be modeled by Poisson point processes (PPPs). This allows for the CRLB of position error to be characterized over all setups of anchor positions and potential target positions realizable within the network. This leads to a distribution of the CRLB, which can …

Practical Algorithms and Analysis for Next-Generation Decentralized Vehicular Networks
… We model the layout of a highway using a 1-D Poisson Point process (PPP) and analyze the performance of a typical receiver in this highway setting. We characterize the success probability of a typical link assuming slotted ALOHA as the channel access scheme. We study the trends in success …

Drone Cellular Networks: Fundamentals, Modeling, and Analysis
… (RS), (iii) random walk (RW), and (iv) random waypoint (RWP), among which the SL mobility model is inspired by the simulation models used by the 3GPP for the placement and trajectory of UAVs, while the other three are well-known canonical models (or their variants) that offer a useful balance …
