Performance Analysis of Multicasting in Cloud-Radio Access Networks
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016Cloud-radio access networks (C-RANs) are considered as energy efficient network architectures. Nevertheless, a dilemma in C-RAN architecture is to simultaneously optimize both spectral efficiency (SE) and energy efficiency (EE). In this paper, the tradeoff between SE and EE are studied considering a downlink multicasting transmission scenario in a C ...

A bandwidth adaptation mechanism for Cloud Radio Access Networks
Pervasive and Mobile Computing, 2017The Cloud Radio Access Network (C-RAN) is regarded as the possible implementation approach of the next-generation mobile networks. C-RAN splits a traditional base station into remote radio heads (RRHs) and the base band unit (BBU). Many BBUs are co-located into a centralized BBU pool.

Optimal load balancing in cloud radio access networks
2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015Cloud radio access network (CRAN) has been seen as an effective means to address the challenges faced by cellular radio networks, such as high capital expenditure and operating expense, high energy consumption and low spectral efficiency. Especially, CRAN has the potential to equip a cellular network with the load-balancing capability to cope with the ...
