Millimeter-wave (mmWave) transmission over the unlicensed 60 GHz spectrum is a potential solution to realize high-speed internet access, even inside mass transit vehicles. The solution involves communication between users and a mmWave-band on-board unit which aggregates/ disseminates data streams from/ to commuters, and maintains connection with th...

In this paper we propose a beam-switching scheme to increase the reliability of the millimeter wave (mm-wave) communication links which are intermittently blocked. We assume that the blockage statistics between the UE equipments (UEs) and the base stations (BSs) change over time. As a result, the data-rates at the UE from different BSs depend not o...

We consider the latency minimization problem in a task-offloading scenario, where multiple servers are available to the user equipment for outsourcing computational tasks. To account for the temporally dynamic nature of the wireless links and the availability of the computing resources, we model the server selection as a multi-armed bandit (MAB) pr...

We study the behaviour of WiFi and 5G cellular networks as they exploit the recently unlocked 6 GHz spectrum for unlicensed access, while conforming to the constraints imposed by the incumbent users. We use tools from stochastic geometry to derive the theoretical performance metrics for users of each radio access technology, which helps us in captu...

More than 40% of the world's population is not connected to the internet, majorly due to the lack of adequate infrastructure. Our work aims to bridge this digital divide by proposing solutions for network deployment in remote areas. Specifically, a number of access points (APs) are deployed as an interface between the users and backhaul nodes (BNs)...

We present a practical framework for maximizing the average data rates of terrestrial networks operating in the 28-GHz band while considering their coexistence with satellite networks. The 28-GHz mmWave band is licensed to fixed satellite services for Earth-to-space uplink transmissions, which are also used by the terrestrial cellular and backhaul...

Digital divide refers to the gap between populations at different socioeconomic levels with respect to their access to the Internet and communication technologies in general. In this chapter, we summarize the recent developments aimed at bridging such inequality from a technical and economic standpoint. After a preliminary discussion on alternative...

The recently unlocked 6-GHz spectrum is accessible to cellular and WiFi networks for unlicensed use while they conform to the constraints imposed by the incumbent nodes. We allow only a fraction of the cellular base stations (BSs) and a fraction of WiFi access points (APs) to use the 6-GHz band so that sources of interference are spatially segregat...

Wireless devices need spectrum to communicate. With the increase in the number of devices competing for the same spectrum, it has become nearly impossible to support the throughput requirements of all the devices through current spectrum sharing methods. In this work, we look at the problem of spectrum resource contention fundamentally, taking insp...

We consider the nonstationary multiarmed bandit framework and propose a Kolmogorov–Smirnov (KS) test based Thompson sampling (TS) algorithm named TS-KS that actively detects change points and resets the TS parameters once a change is detected. In particular, for the two-armed bandit case, we derive bounds on the number of samples of the reward di...

In this paper, the measurement data of an outdoor-to-indoor channel at 60 GHz for various orientations of the receiver is analyzed. We comment on the variation of the received line-of-sight (LOS) component power and delay spread with respect to the misalignment angle and suggest the existence of clusters which map to nearby buildings acting as scat...

We study a self-organizing wireless network in which the number of active connections to the typical user equipment (UE) is dynamic, in order to sustain temporally varying network traffic. Using tools of stochastic geometry, we show that even though the signal coverage improves with a higher degree of connectivity, the per-user throughput may degra...

In this paper, we study the time-variance of a roadside infrastructure to infrastructure (I2I) channel operating at 60 GHz millimetre wave (mmWave) band, where the time-variance is caused by moving vehicles acting as scatterers. At first, measurement data is obtained by placing the transmitter (TX) and the receiver (RX) at different heights to emul...

In this work, we propose a physical approximation scheme-Random Opportunistic and Selective Exploration (ROSE)-for aerial localization of survivors by using a collab-orative swarm of IoT-based unmanned aerial vehicles (UAVs). The UAV swarm performs a simultaneous multi-pronged search of a given zone by dividing the search region among the swarm mem...

In this paper, we have proposed a framework to model the server nodes' non-stationary reward distribution as an N-state Markov chain derived from the long-term probability distribution of the reward, in which the state transitions occur at an interval defined as a non-homogeneous Poisson process. The framework aims to serve as a tool for validation...

This paper analyzes the data obtained from a 60 GHz infrastructure-to-infrastructure millimetre wave channel sounding campaign, carried out in an urban-highway environment in Brno, Czech Republic. The transmitter and the receiver are placed at different heights to emulate a link between a typical base station and a roadside unit while the passing v...

The 5G vision acknowledges intravehicular communication as a means to enable passenger connectivity on the move. The capacity demand in a public transport vehicle is multi-fold compared to personal cars as there are more people on-board. In order to meet the demand, 5G standardization bodies prescribe moving the spectrum up to the millimetre wave (...
