    Evaluation of controller placement approaches in SDN-based 5G networks
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Agarwal, Lakshita; Sharma, Jalaj
    The thesis work provided the relevant information about the SDN-based 5G networks, with the controller placement problem as well as the average latency between the nodes of the networking system. Software-defined networking (SDN) is a technology that is emerging in today’s world and it is mainly used for changing the state of the network by breaking the older version of it and by separating the network’s control layer from the layer of the routers and switches. With the evolution of the fifth generation, i.e., 5G networks, there is a steady growth in the development of different business models as well as new applications are being developed. For the development of the 5G networking and for the formation of different intelligent networks and applications, SDN technology has been considered as a key enabler. The main aim of this work is about the evaluation of the already existing controller placement approaches i.e., K-Median, K-Center and Kcritical Approaches for SDN-Based 5G networking system. The proposed work is an approach for analyzing the solutions for the placement of the controller inside the SDNbased 5G network. In this work, the network topology of 250 nodes was created and the evaluation of the three different approaches was being done. It was also concluded that out of all the three approaches the K-Critical approach can be considered as one of the best approaches for the selection of the controller inside the SDN-based 5G networks because all the criterions in this approach were satisfied according to the requirements.
