Efficient mobility management solutions are essential to provide users with seamless connectivity and session continuity during movement. However, user mobility was not envisaged as one of the early Internet’s use cases due to the early adoption of destination based routing and the assumption that end-nodes are static. This has become a critical hinder for providing efficient mobility support. This paper presents the challenges, drivers, and solutions that aim to overcome the drawbacks of current mobility management approaches. Furthermore, it introduces a promising solution that builds on emerging path-based forwarding architectures that identify network links rather than end nodes. Delivery path information is stored inside the packet while forwarding is achieved by performing a simple set membership test rather than the current destination-based routing approach. Mobility management in these architectures simply requires partial recomputation of the delivery path allowing for efficient mobility support over an optimal path. Evaluation results show significant cost savings in terms of delivery paths and end-to-end packet delay when using a path forwarding architecture.

“…Today, the most known approach is testing mobile flow entries against matching rule fields and finding a correct output action through every OpenFlow switch along the path, which has high costs in mobile flow management. Most of the proposed SDN architectures in wireless networks cannot be directly applied to large-scale networks due to this reason [35]. OpenFlowenabled proxy mobile IPv6 (OF-PMIPv6) is proposed in [36] where the control path is separated from the data path by performing the mobility control at the controller, whereas the data path remains direct between the MAG and the LMA in an IP tunnel form.…”

Efficient mobility management techniques are critical in providing seamless connectivity and session continuity between a mobile node and the network during its movement. Current mobility management solutions generally require a central entity in the network core, tracking IP address movement and anchoring traffic from source to destination through point-to-point tunnels. Intuitively, this approach suffers from scalability limitations as it creates bottlenecks in the network, due to sub-optimal routing via the anchor point. Meanwhile, alternative anchorless, solutions are not feasible due to the current limitations of the IP semantics, which strongly ties addressing information to location. In contrast, novel path-based forwarding solutions may be exploited for feasible anchorless solutions. In this paper, we propose a novel network-based mobility management solution that facilitates IP mobility over such a path-based forwarding substrate. Our solution exploits the advantages of such substrates in decoupling path calculation from data transfer to eliminate the need for anchoring traffic through the network core; thereby, allowing flexible path calculation and service provisioning. Furthermore, by eliminating the limitation of routing via the anchor point, our approach reduces the network cost compared to anchored solution through bandwidth saving while maintaining comparable handover delay. We evaluate our solution through analytical and simulation models and compare it with the IETF standardized solution, Proxy Mobile IPv6 (PMIPv6). Evaluation results illustrate a significant saving in the total network cost when using our proposed solution, compared to its counterpart.Index Terms-IP-over-ICN, Mobile IP, Proxy MIPv6, LTE, GPRS, Handover.

“…Handover management mechanisms for WLANs are proposed in [4,6,7,9,10]; however, the handover processes described in the papers are initiated by the mobile devices. As a result of this type of handover process, the communication of the ongoing sessions is disconnected and it can resume only after the handover is completed.…”

Various applications used by mobile users today need seamless connectivity for providing a good quality user experience. Enterprise Wireless Local Area Network (WLAN) is one of the technologies used by mobile devices to connect to the Internet in several environments. For providing seamless connectivity and communication, mobility management becomes an important aspect of such deployments. In this paper, we propose a client-unaware handover process for NAT (Network Address Translation) operation mode of the access points in a Software Defined Networking (SDN) based enterprise WLAN framework. The proposed mechanism has been implemented in simulation and the results show that the proposed mobility management mechanism is able to achieve seamless handover and provide uninterrupted connectivity and communication to the mobile devices.
