Temporal Correlation of Interference in Bounded Mobile Ad Hoc Networks with Blockage

TL;DR

This paper investigates how obstacles affect the temporal correlation of interference in mobile ad hoc networks, revealing that blockage increases correlation in dense networks but decreases it in sparse ones.

Contribution

It introduces a model that accounts for spatial correlation due to obstacles, showing how blockage impacts interference correlation depending on network density.

Findings

Blockage increases interference correlation in dense networks.

Blockage decreases interference correlation in sparse networks.

The model highlights the importance of obstacle density in interference analysis.

Abstract

In mobile wireless networks with blockage, different users, and/or a single user at different time slots, may be blocked by some common obstacles. Therefore the temporal correlation of interference does not depend only on the user displacement law but also on the spatial correlation introduced by the obstacles. In this letter, we show that in mobile networks with a high density of users, blockage increases the temporal correlation of interference, while in sparse networks blockage has the opposite effect.
