CHetNet: crowdsourcing to heterogeneous cellular networks

IEEE Network, 2015
Heterogeneous networking (HetNet) is a promising solution to meet the ever increasing demands of wireless applications. However, it is a significant challenge for mobile network operators to deploy HetNet at a large scale. To address this issue, this article discusses a new paradigm in which potential partners are encouraged to participate in ...

Delay analysis of heterogeneous cellular networks

2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015
Due to a wider range of services in future heterogeneous cellular network (HCN), packet transmission delay becomes a more essential performance metric for system design. In this paper, we propose an analytical framework to derive the delay performance of HCN in terms of local delay, by modeling the locations of base stations (BSs) in HCN as ...

Energy Efficient Heterogeneous Cellular Networks

IEEE Journal on Selected Areas in Communications, 2013
With the exponential increase in mobile internet traffic driven by a new generation of wireless devices, future cellular networks face a great challenge to meet this overwhelming demand of network capacity. At the same time, the demand for higher data rates and the ever-increasing number of wireless users led to rapid increases in power consumption and

Cooperative retransmission in heterogeneous cellular networks

2014 IEEE Global Communications Conference, 2014
This paper studies spatiotemporal cooperation between base stations in the presence of interference in a heterogeneous cellular network. The focus of the paper is the cooperative retransmission scenario, where a set of randomly located base stations that are selected based on their average received powers, possibly belonging to different network tiers,

Load Distribution in Heterogeneous Cellular Networks

IEEE Communications Letters, 2014
This letter provides the distributions on the association region of a small-cell BS (sBS) and that of a macro-cell BS (mBS) in a two-tier heterogeneous cellular network (HCN) as functions of the power and density ratios between tiers. Computer simulation results confirm that the proposed distributions are quite accurate for a wide range of network ...

Analysis of Coverage in Heterogeneous Cellular Networks

IEEE Communications Letters, 2016
In this letter, we study the coverage of base stations (BSs) in heterogeneous cellular networks, where BSs with different transmit powers are randomly deployed. Specifically, the boundary of coverage is formulated analytically as the intersection of circles when a multiplicative bias is applied for BS association.

Capacity growth of heterogeneous cellular networks

Bell Labs Technical Journal, 2013
Heterogeneous cellular networks are composed of a mixture of macro and small (pico) cells embedded in the macro network. We assume uniform traffic for simplicity, and study the scaling of area spectral efficiencies (ASEs) as pico densities are increased, optimizing over transmit power and cell association bias.

Energy Efficiency of Heterogeneous Cellular Network

2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010
The growing energy consumption driven by dramatic increases in the number of users and data usage becomes the key issue for operators in meeting demands on cost reduction and environmental impact targets. Deployment of low power base stations or relay stations in traditional macro cells is expected to reduce the total energy consumption of cellular ...

Scheduling in heterogeneous cellular networks with mobility

2012 Information Theory and Applications Workshop, 2012
We examine the scheduling problem in the context of heterogeneous cellular networks in the presence of mobility. We demonstrate that the QoS for users in a cellular network can be optimized using an interference-aware approach that is most effective at low Doppler frequency scenarios or a channel-aware approach that is most effective at higher low ...
