    Design and implementation of SDN-based handover in 5G mmWave
    (Institute of Electrical and Electronics Engineers Inc., 2021) Dhruvik, N.; Karia, A.J.; Khatri, A.; Manjappa, M.
    5G networks are more reliable than the widely used 4G network. They have extremely low latency and greater capacity. Apart from these benefits, 5G networks have speeds ranging from 1 gigabit - 10 gigabits per second. For accommodating such high rates, the User Equipment(UE) has to continuously keep switching between base stations once the signal from the previous is below some threshold. This is known as handover. Further, in a 5G scenario, where the base station coverage area is much smaller compared to 4G, UE frequently encounters handover because of its mobility. Hence, an efficient handover algorithm is required, and Software-Defined Networking (SDN) is the best option to design such algorithms. SDN, a fore-front technology, uses software-defined controllers which enable the centralised supervision of the entire network. The proposed research work has defined a software controller based handover for the 5G mmWave, which ensures Quality of Service(QoS) to the UEs. For the communication, a new interface called HOinterface has also been defined. The proposed architecture reduces the handover delay and is flexible, scalable, and efficient. The proposed SDN architecture is implemented in the NS3-mmWave patch and it was evaluated for its strengths and weaknesses. The results obtained are encouraging. © 2021 IEEE.

    Optimal Quadcopter Placement using Brute Force method for Efficient 5G Communication
    (Institute of Electrical and Electronics Engineers Inc., 2022) Kanapuram, K.; Priyanka, B.; Manohar, S.; Manjappa, M.
    Quadcopters are finding its application in many areas nowadays. Fifth Generation (5G) mobile communication is one area where quadcopters can be made used to assist in providing mobile communication. Quadcopters can be deployed to provide 5G mobile network communication in areas where the network is down due to natural calamities. And there are situations where the network coverage has to be extended temporarily to provide temporary service on demand, for example, when there is an outdoor gathering at a place where mobile network coverage is unavailable. The quadcopters can also be used to assist terrestrial base stations, also called eNodeB, when it is down or overloaded with many users. In all the above cases the quadcopter can be made use of by making it to hover in the dedicated geographical area to provide 5G network service. The ideal height and exact location at which the quadcopter should hover is dependent on the number of users and how they are scattered in the area under consideration. This article focuses on ideal quadcopter placement by finding all the axes in 3 dimension for the quadcopter to hover so that the network coverage and Quality of Service (QoS) to all users is optimal. © 2022 IEEE.
