Distributed Location Algorithms for Flexible BBU Hotel Placement in C-RAN
Carla Raffaelli, Bahare M. Khorsandi, Federico Tonini · 2018
Cloud Radio Access Networks (C-RAN) are characterized by huge introduction of Network Function Virtualization (NFV) supported by software-based control of relevant functionalities within the Software Defined Network (SDN) context. Distributed location algorithms, as a practical approach to optimally locate virtual functionalities in C-RAN, are described and compared to conventional optimization techniques, with application to BBU hotel placement and extensions to dynamic evolution of C-RAN configuration. Near optimal solutions and incremental adaptability to topology changes are achieved.
