Cloud Radio Access Networks virtualization Research Project Topics

C-RAN stands for Cloud Radio Access Network, which is a wireless network architecture widely used nowadays in the telecommunication industry. In this research paper you can learn about this technology and how it is different from the traditional one and also the algorithms used in it.

  1. What is C-RAN?

C-RAN is Cloud RAN, and it is otherwise known as Virtualized RAN (V-RAN) Centralized-RAN (C-RAN). This is a new cellular architecture which is based on the principles of cloud computing. This follows a little different architecture from regular RAN architecture which is mentioned below:

  • Centralization: The C-RAN centralizes the function of radio access network in the cloud data center which improves scalability and flexibility. This will easily allow expanding and managing the network without using any extra dedicated hardware.
  • Virtualization: This technology is used by C-RAN to run several RAN functions over single server, which will result in reduced dedicated hardware and increase in utilization of resources.
  • Openness: The open standards and interfaces which are encouraged by C-RAN will allow more participants for deploying and developing technologies. This will further increase the innovation and competing among users.
  1. Previous Technology Issues in C-RAN

One of the major problems faced by C-RAN is latency constraints when data is transmitting within data center and cell sites. This technology includes more complexity, so it should be carefully planned and implemented. C-RAN also has some issues related to security which has to be solved.

  1. Algorithms / Protocols

The algorithms provided for C-RAN in Multimedia applications to overcome the previous issues faced by it are: “Modified Energy Efficient VM Placement with Extended Flower Pollination algorithm” (MEEVMP-EFPA), “K-means clustering method, Energy-efficient Trajectory Optimization of UAV–IoT using genetic algorithm” (GA) (EETO-GA), “Multi-agent DRL Approach with Proposed Resource Allocation Approach” (M-AC-VNE-PW-DRL), “Buffer length based priority queue” (PQ), “Weighted round-robin” (WRR) and “Deficit round-robin (DRR)”.

  1. Comparative study / Analysis
  2. The integration of “Modified Energy Efficient VM Placement with Extended Flower Pollination algorithm” (MEEVMP-EFPA) is made to reduce the energy consumption of data center with the help of ideal and effective strategy for placement of virtual machine.
  3. Multi-agent DRL Approach withProposed Resource Allocation Approach” (M-AC-VNE-PW-DRL) framework is used for resource allocation with the help of online time-sequential resource.
  4. The algorithms such as “Deficit round-robin (DRR)”, “weighted round-robin” (WRR) and “Buffer length based priority queue” (PQ) are used for scheduling task when there is a usage of applications which has minimal latency.
  5. The “K-means clustering method” is created to solve the problems like ILP issues which arise in bigger networks.
  6. “The Energy-efficient Trajectory Optimization of UAV–IoT using genetic algorithm” (GA) (EETO-GA) is designed to monitor the energy spent, jobs completed and to find the devices which can do service with the help of GA.
  7. Simulation results / Parameters

The approaches which were proposed to overcome the issues faced by C-RAN Multimedia Applications are tested using different methodologies to analyze its performance. The comparison is done by using metrics like Execution time Vs. Number of virtual machine(VM), Number of RRH (Remote Radio Head) Vs. Cost (million $), Power consumption Vs. Size of datacenter, Transmission time interval Vs. Markov process state, Energy consumption Vs. Network size (no. of nodes), Time[s] Vs. Throughput rate (Mbps), Transmission time interval Vs. DTT(delay-throughput-tolerant) transmission rate.
