Slotted Aloha for Networked Base Stations [PDF]
arXiv, 2014 We study multiple base station, multi-access systems in which the user-base station adjacency is induced by geographical proximity. At each slot, each user transmits (is active) with a certain probability, independently of other users, and is heard by all base stations within the distance $r$.

3D Deployment of Unmanned Aerial Vehicle‐Base Station Assisting Ground‐Base Station [PDF]
Wireless Communications and Mobile Computing, 2021 Unmanned aerial vehicles (UAVs), also named as drones, have become a modern model to provide a quick wireless communication infrastructure. They have been used when conventional base stations’ capacity is suffering in some extreme cases such as congestion inside the cell or a special event.

On the Base Station Selection and Base Station Sharing in Self-Configuring Networks [PDF]
Proceedings of the 4th International ICST Conference on Performance Evaluation Methodologies and Tools, 2009 We model the interaction of several radio devices aiming to obtain wireless connectivity by using a set of base stations (BS) as a non-cooperative game. Each radio device aims to maximize its own spectral efficiency (SE) in two different scenarios: First, we let each player to use a unique BS (BS selection) and second, we let them to simultaneously use

Group Handover for Drone Base Stations [PDF]
IEEE Internet of Things Journal, 2021 The widespread use of new technologies such as the Internet of things (IoT) and machine type communication(MTC) forces an increase on the number of user equipments(UEs) and MTC devices that are connecting to mobile networks. Inherently, as the number of UEs inside a base station's (BS) coverage area surges, the quality of service (QoS) tends to decline.
