Leveraging SDN for Handover in Distributed Mobility Management of 5G Network

Abstract

Distributed Mobility Management (DMM) is considered by many to be a suitable mobility management system for future 5G network. This approach implements flatter and more flexible architecture by distributing the data plane among the networks. Data traffic is not traversed to core but segregated locally, making it closer to the edge of the network. This can be achieved by implementing Software Defined Network (SDN) paradigm, i.e. separating control and data plane This paper surveys and analyzes numerous related work on DMM for 5G network particularly on handover protocol Those proposed solutions are in different in terms of architectures and procedures. Some of them can also be referring to quite similar concept under different nomenclature There are two proposed solutions for handover in DMM, SDN-based handover without tunneling and SDN-based handover with tunneling. The comparative analysis between those two are presented as well
