Delay Guaranteed Network Association for Mobile Machines in Heterogeneous Cloud Radio Access Network

IEEE Transactions on Mobile Computing, 2018
In the heterogeneous cloud radio access network (H-CRAN), which consists of multiple access points (APs) providing smaller coverage and a high power node (HPN) providing ubiquitous coverage, the mobile machines can connect to multiple APs and HPN by coordinated multi-point transmission (CoMP) concurrently to achieve ultra-reliable and low-latency ...

Energy Efficient Resource Allocation in Heterogeneous Cloud Radio Access Networks

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Energy harvesting is becoming an attractive option of energy supply for wireless networks as it can effectively reduce capital expenditure (CAPEX) and operational expenditure (OPEX). In this paper, an energy efficient radio resource optimization algorithm is proposed for a two-tier heterogeneous cloud radio access network (H-CRAN) where macro cells are

Software-defined handover decision engine for heterogeneous cloud radio access networks

Computer Communications, 2018
Abstract The current telecommunication infrastructure is reaching its limits, no longer able to cope with the ever-growing number of connected devices and data traffic summed to the future QoS demand of 5G. To overcome such limitations, the Heterogeneous Cloud Radio Access Network (H-CRAN) has been considered as a promising architecture that includes

Collaborative radio access of heterogeneous cloud radio access networks and edge computing networks

2016 IEEE International Conference on Communications Workshops (ICC), 2016
Although the technical merits of the heterogeneous cloud radio access networks (H-CRAN) architecture have been well demonstrated in terms of data rate enhancement and ubiquitous wireless service provisioning, solely relying on the H-CRAN may not be sufficient to further support full automation and everything-to-everything (X2X) connection for the next ...

Resource Optimization in Heterogeneous Cloud Radio Access Networks

IEEE Communications Letters, 2018
This letter tackles the problem of sum-rate maximization via joint user association and power allocation in heterogeneous cloud radio access networks, while guaranteeing the quality-of-service requirements of all users. A generalized Stackelberg game is applied to this problem with the coupled strategy set of power allocation, and a centralized ...
