Correlated Interference from Uncorrelated Users in Bounded Ad Hoc Networks with Blockage

TL;DR

This paper investigates how user density, blockage, and deployment boundaries influence interference correlation in ad hoc networks, revealing that interference can remain correlated despite uncorrelated user locations, especially with blockage and bounded areas.

Contribution

It provides new insights into interference correlation behavior considering blockage and bounded deployment areas, which were not thoroughly analyzed before.

Findings

Interference remains correlated despite uncorrelated user locations.

Blockage and bounded areas significantly influence interference correlation.

Correlation coefficients scale with high blockage density.

Abstract

In this letter, we study the joint impact of user density, blockage density and deployment area on the temporal correlation of interference for static and highly mobile users. We show that even if the user locations become uncorrelated, the interference level can still be correlated when the deployment area is bounded and/or there is blockage. In addition, we study how the correlation coefficients of interference scale at a high density of blockage.
