Downlink outage performance of heterogeneous cellular networks [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper derives tight performance upper and lower bounds on the downlink outage efficiency of K-tier heterogeneous cellular networks (HCNs) for general signal propagation models with Poisson distributed base stations in each tier. In particular, the proposed approach to analyze the outage metrics in a K-tier HCN allows for the use of general bounded

Design of a Heterogeneous Cellular Network With a Wireless Backhaul [PDF]
IEEE Transactions on Wireless Communications, 2017 The downlink of a two-layered heterogeneous network is studied with macro basestations (MBs), small-cell basestations (SBs) that act as half-duplex analog relays, and mobile terminals (MTs). The first layer is a wireless backhaul layer between MBs and SBs, and the second is the transmission layer between SBs and MTs.

OPTIMIZING QOS IN SELF ORGANIZING HETEROGENEOUS WIRELESS CELLULAR NETWORK USING FIREFLY ALGORITHM
ICTACT Journal on Communication Technology, 2022 Capacity and energy efficiency are crucial for next-generation wireless networks. Due to the dense deployment of base stations (BSs) in a heterogeneous network (HetNets), the consumption is from 60% to 80% of the total energy causing accentuated costs ...

Transfer restless multi-armed bandit policy for energy-efficient heterogeneous cellular network
EURASIP Journal on Advances in Signal Processing, 2019 This paper proposes a learning policy to improve the energy efficiency (EE) of heterogeneous cellular networks. The combination of active and inactive base stations (BS) that allows for maximizing EE is identified as a combinatorial learning problem and ...

Decentralized resource allocation for heterogeneous cellular networks [PDF]
2017 International Symposium on Wireless Communication Systems (ISWCS), 2017 Heterogeneous cellular Network (HetNet) is a promising technology for 5th generation mobile networks (5G) that can potentially improve spatial resource reuse and extend coverage, therefore allowing it to achieve significant higher data rates than single tier networks.

Spatial spectrum and energy efficiency of random cellular networks [PDF]
, 2015 It is a great challenge to evaluate the network performance of cellular mobile communication systems. In this paper, we propose new spatial spectrum and energy efficiency models for Poisson-Voronoi tessellation (PVT) random cellular networks. To evaluate

On Optimal Geographical Caching in Heterogeneous Cellular Networks [PDF]
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017 We investigate optimal geographical caching in heterogeneous cellular networks, where different types of base stations (BSs) have different cache capacities. The content library contains files with different popularities. The performance metric is the total hit probability.

Hierarchical Federated Learning ACROSS Heterogeneous Cellular Networks [PDF]
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020 We study collaborative machine learning (ML) across wireless devices, each with its own local dataset. Offloading these datasets to a cloud or an edge server to implement powerful ML solutions is often not feasible due to latency, bandwidth and privacy constraints.
