Optimal bandwidth utilization and energy efficiency in C-RAN for 5G wireless communication

Abstract

Mobile communication play a vital role in human life and a new era is yet to evolve with 5G Technology. Cloud Radio Access Network (C-RAN) with Remote Radio Head (RRH) and Baseband unit (BBU) pool is meant for high spectrum efficiency and considered to be as a dominant realization of mobile networks with open platform supporting green infrastructure and paves way for emerging technology in 5G mobile networks. This blooming technology provides a pioneering approach to encounter the requirements and progress the network to deliver coverage, innovative services and lower support costs. This results in enhancement of network performance, in addition with resource utilization. This paper proposes a BBU and RRH association scheme with opportunistic coordinated selective forwarding using duplicate detection distributed Ex-or to utilize the appropriate bandwidth, reduce the latency of transmitted packets and thereby reducing energy consumption in future wireless communication. Results reveals that opportunistic coordinated selective forwarding method yields better performance in all aspect for 5G communication system.
