Distributed Location Algorithms for Flexible BBU Hotel Placement in C-RAN

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 Soft- ware Dened Network (SDN) context. Distributed location algorithms, as a practical approach to opti- mally 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 conguration. Near optimal solutions and incremental adaptability to topology changes are achieved.
