Poisson point process-based network modelling and performance analysis of multi-hop D2D chain relay formation in heterogeneous wireless network

Abstract

This article presents stochastic geometry-based unified analytical framework to analyse the functionality of device-to-device (D2D) assisted cellular network in inband overlay mode. Independent marked Poisson point process (imPPP) is incorporated to probabilistically model the aggregate interference and SINR distribution of the randomly distributed nodes in the spatial domain. The proposed framework is applied to evaluate the overall network coverage probability improvement due to minimisation of congestion in the base station oriented core network by involving more devices in direct communication (through traffic offloading). Statistical analysis of slotted-synchronous and slotted-asynchronous traffic patterns in terms of throughput for varying transmission probability is also presented. From the application point of view, in the case of base station service interruption due to any natural calamity or power failure, the proposed multi-hop D2D chain relay formation helps to extend the cellular coverage in cell edges as well as in adjacent affected cell areas.

Reliability in Post-Disaster Networks: A Novel Interference-Mitigation Strategy

“…The second main branch relates to SG modeling of D2D networks for PDCs [12]- [14]. In [12], the authors considered both uplink and downlink connections, and introduced a novel analytical framework to evaluate the effect of a calamity on the network's coverage.…”

“…Moreover, authors in [13] jointly optimized the fraction of spectrum allocated to D2D communications and the small BSs' power and density in order to maximize the system throughput in emergency scenarios. Finally, the authors of [14] used marked Poisson point processes in order to model the aggregate interference and SINR distribution in D2D-aided networks in inband overlay mode.…”
