Distributed mobility management based on centrality for dense 5G networks

This paper presents distributed mobility management techniques for 5G networks based on the centrality of the nodes in the network. This centrality concept is introduced for the 5G network as a mean for the definition of mobility anchors and the data forwarding nodes in the network. The corresponding distributed mobility management scheme is then simulated through simplified system level simulations. The performance of the proposed distributed mobility management is compared to that of legacy mobility management systems based on LTE and DMM. It is seen that the performance of the proposed system improves the performance of the legacy mobility management of about 14%.
