Title
Split Point Selection Based on Candidate Attachment Points for Mobility Management in SDN.
Abstract
Seamless mobility is essential in future wireless networks to support multimedia rich realtime services. Software Defined Networking (SDN) is a new networking paradigm which can provide fine grained flow level mobility management in wireless networks through centralized controller, but suffers from intolerable handover delay. Split point approach is an effective way to reduce handover and end-to-end transmission delay in SDN wireless networks. The split point is a switch on the existing flow path from where traffic is rerouted towards new Attachment Point (AP) after handover. This paper presents a split point selection algorithm which utilizes a list of candidate APs for next handover of Mobile Node (MN) to determine topologically most efficient split point in terms of handover delay. Proposed algorithm calculates the weight of each switch in the MN-Corresponding Node (CN) path as the average distance (hop) between a switch and the candidate APs, and the switch with the minimum weight is selected as the split point. In addition to split point selection, this paper exploits the control and data plane separation provided by SDN to restore optimal path for a flow after the handover. The numerical analysis of the proposed scheme shows 9.6% to 13% total cost improvement in comparison to previous solution.
