Stable Matching-based Mobility Agent Selection in Distributed Mobility Management

Abstract

In partially distributed mobility management (P-DMM), location management functions are centralized whereas data forwarding functions are distributed to DMM gateways (DMM-GWs). Since all packets are processed by DMM-GWs, which one is selected as a serving DMM-GW has a significant impact on the performance of mobile nodes (MNs). In this paper, we propose a stable matching-based DMM-GW selection scheme considering the preferences of both DMM-GWs (w.r.t. load balancing) and MNs (w.r.t. location update cost). Evaluation results demonstrate that the proposed scheme generates about 50% location update cost while the load fairness increased to 0.75 in the most unbalanced mobile distributed state.
