Spectrum sharing in D2D enabled HetNet

2015 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2015
This demonstration presents dynamic spectrum use by an overlay Device-to-Device (D2D) connection in a Heterogeneous Network (HetNet) environment. D2D devices can reuse the uplink resources of the cellular network. In a HetNet, the cellular users should be protected from excessive interference from the D2D connections.

Interference and QoS Aware Cell Switch-Off Strategy for Software Defined LTE HetNets

Journal of Network and Computer Applications, 2019
LTE-Heterogeneous Networks (HetNets) with dense deployment of small cells are expected to effectively meet unprecedented ever increasing data traffic demands and offer improved coverage in indoor environments. However, HetNets are raising major issues to

Hierarchical network abstraction for HetNet coordination

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
We consider a user-centric network-level coordination architecture for 5G heterogeneous Radio Access Networks (RANs), based on RAN softwarization and a centralized coordination framework. We describe the RAN as a set of logical RAN entities, related to cells in a Heterogeneous Network (HetNet), under the control of a central coordination entity.

Interference Management in HetNets

2015
The capacity and the coverage of any wireless network can be improved in terms of efficiency by moving the transmitter and the receiver closer together. Therefore, the concept of small cells overlapping with traditional macrocells is gaining considerable research attention. However, the mass deployment of HetNets introduces certain challenges that must

Performance Analysis of Multi-Antenna HetNets

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016
We propose an analytical stochastic geometry-based model for multiple-input multiple-output (MIMO) heterogeneous cellular networks (HetNets) with zero-forcing (ZF) precoding at transmitting base stations (BSs) and partial zero-forcing (PZF) beamforming at receiving user equipments (UEs). The user and area spectral efficiencies are characterized using a

Sparse Spectrum Reuse in HetNets with Relays

2018 IEEE Global Communications Conference (GLOBECOM), 2018
In-band relay nodes (RNs) can be utilized to enhance the coverage of heterogeneous networks (HetNets) in a cost-effective way. However, the in-band RNs also consume the limited spectrum resources. Appropriate spectrum resource management/cooperation is necessary to ensure the balanced resource usages between the macro base stations (BSs) and the

Security Challenges and Solutions for 5G HetNet

2020 IEEE 19th International Conference on Trust, Security and Privacy in Computing and Communications (TrustCom), 2020
The exponential growth of smartphones and other smart communicating devices has led to the proliferation of the Internet of Things (IoT) applications. Literature shows, one person will have more than six intelligent connected devices in future. The existing network infrastructure and bandwidth will be unable to accommodate the growing number of smart ...

HetNet Framework for Supply Chain Management

2012 15th International Conference on Network-Based Information Systems, 2012
In this paper, we introduce a service framework for supply chain management, which runs on a heterogeneous network and leverages the power of an inference engine to manage networks and supply chain entities. Details of design and implementation of the framework are given along with the discussions on the preliminary experimental results and impacts for

HetNet capacity with reduced power subframes

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
The time domain inter-cell interference coordination (eICIC) mechanism specified in LTE Rel. 10 improves the throughput of picocell-edge users by protecting them from macrocell interference. On the other hand, it also degrades the aggregate capacity in macrocell because the macro base station (MBS) does not transmit data during the coordinated ...

Intelligent Architecture for Mobile HetNet in B5G

IEEE Network, 2019
Since traffic in networks is growing rapidly, it is difficult for the existing network architecture to support the huge traffic requirement. This article proposes a novel intelligent architecture as a promising paradigm for B5G heterogeneous networks to optimize network resource usage and network performance.
