A Software Defined Networking Based Adaptive Multimode Decentralized Mobility Architecture for 5G

Abstract

This thesis presents a novel Software-Defined Networking based flexible handover management mechanism for 5G mobile networks. The performance of Distributed Mobility Management process is enhanced through a novel 'Handover Mode Selection' approach, in which the Software-Defined Network Controller evaluates the protocol's mode of operation for the next handover event according to the Mobile Node's current mobility profile. The analytical evaluation and the simulations through ns-3 network simulator of the proposed solution show significant handover performance improvement under high mobility and high session activity scenarios.
