The issue of data pricing is becoming more important than before in order to build an
internet ecosystem. In this paper, we consider a data redistribution market where users with …

The dense deployment of small cells has been considered as a promising approach to
providing high quality of service (QoS) to mobile users. However, the resulting dense short …

Caching popular contents at mobile devices can improve the system performance and
relieve the traffic burden for the device-to-device (D2D) enabled mobile ultra dense network …

In this paper, we investigate the problem of content caching in wireless cellular networks
(CN) using device-to-device (D2D) transmission method to reduce subscriber's download …

Joint transmission across the cluster of radio remote heads (RRHs) by exploiting the
centralized processing of the cloud-radio access network (C-RAN) is a promising technique …

Coordinated multi-point (CoMP) transmission clustering schemes could provide significant
gains of system performance, such as throughput and cell-edge user data rates. Due to …

In this paper, we develop an adaptive remote radio head (RRH) control scheme to maximize
the network capacity of frequency division duplexing (FDD)-based cloud radio access …

ABSTRACT Radio Access Network (RAN) disaggregation allows operators to mix-and-
match multivendor components and bring RAN services from one end to the other. Despite …

Improving energy efficiency (EE) of mobile communication systems (MCSs) has been
considered a key aim in recent years, and has been the subject of intense research interest …

In the last decades, the rapid increase of user traffc demand for better user experience has
pushed the traditional macrocell-only networks being evolving to modern heterogeneous …
