Saddle point problems arise from many wireless applications, and primal-dual iterative
algorithms are widely applied to find the saddle points. In the existing literature, the …

Cache-enabled network architecture has great potential for enhancing the efficiency of
content distribution as well as reducing the network congestion. This, in turn, has called for …

This paper investigates downlink distributed power control for femtocell networks with QoS
provisioning for macro-cell user equipments (MUE). Specifically, we propose two non …

The convergence properties of the iterative water-filling (IWF) based algorithms have been
derived in the ideal situation where the transmitters in the network are able to obtain the …

We propose a handover (HO) strategy that helps minimize energy consumption at base
stations (BSs) in heterogeneous networks. To conserve energy at BSs, the proposed …

Distributed network utility maximization (NUM) has received an increasing intensity of
interest over the past few years. Distributed solutions (eg, the primal-dual gradient method) …

Distributed power control for parallel Gaussian interference channels recently draws great
interests. However, all existing works only studied this problem under deterministic …

To cope with the ever-increasing cellular traffic demand, the heterogeneous network is
introduced to densify the cells for places where that is most needed. However …

In this paper, we investigate the convergence behavior of the primal-dual scaled gradient
algorithm (PDSGA) for solving distributed network utility maximization problems under time …
