“…And owing to this type of topology, the network based on ring can consolidate both metro and access systems into a single network and provide large capacity for users easily [22,23]. But, since both downstream and upstream signals in conventional ring scheme are transmitted in only one direction [15][16][17][18], unlike the case in tree-based network, the receiving power in each node is widely different because of a significant diversity in link loss. And as the number of user increases in future, such heterogeneity of receiving power will be further enlarged.…”

“…Relying on the superiority of its physical topology, single-fiber ring-based networks can provide self protection without any redundant protection fiber [13][14][15][16]. To against simultaneous failure of multiple fibers in the network, there are some dual-fiber ring-based networks proposed [16][17][18][19][20][21].

Abstract. In the mobile Internet and big data era, wireless networks are facing challenges to transmit the huge amount of data effectively, efficiently and reliably. To deploy a network infrastructure with larger capacity, higher data rate, lower transmission delay, higher spectral efficiency and lower energy consumption, an innovative architecture-the Cloud-Radio Access Network (C-RAN) has been proposed. In this paper, we focus on network planning deployment issue based on the Optical Mixed Diet (OMD) technology. Specifically, the ring and spur topology Optimization (RSTO) problem under the C-RAN architecture is investigated. We solve this RSTO problem using Gurobi. A series of case studies are conducted to validate the optimization framework and demonstrate the solvability and scalability of the RSTO problem. Results also show that cost saving can be achieved by taking advantage of Coordinated Multi-Processing (CoMP) technology.

With the development of user-centered and environment sensing technology of 5G, large capacity and ubiquitous coverage and massive data collection and processing will bring new challenges in wireless networks. The cloud radio access network (C-RAN) has been envisioned to provide a new wireless architecture for reliable transmission of mobile big data. In this paper, we focus on network planning deployment issue based on the optical mixed diet (OMD) technology. Specifically, the ring and spur topology optimization (RSTO) problem under the C-RAN architecture is investigated. The RSTO problem is formulated as a generic integer linear program (ILP) which can optimally (i) minimize the network deploying cost; (ii) identify the locations of Remote Radio Units (RRUs) and optical add-drop multiplexers (OADMs); (iii) identify the association relations between RRUs and OADMs; and (iv) satisfy the mobile coverage requirements so as to allow the mobile big data to be transmitted through the RRUs. We propose a new heuristic algorithm based on C-RAN architecture. Numerical results validate the ILP formulation and show the performance benefits of the proposed algorithm in terms of efficiency and effectiveness against Gurobi, which is an ILP solver. In numerical studies, we also demonstrate the performance benefits of the incorporation of CoMP technology in terms of total deployment cost reduction.
