Contribution:

In this paper we present an architecture that tackles the two key challenges highlighted above: interference and mobility management in wireless dense networks. Furthermore, we show that a SDN-based networking approach can be suitably adopted to design the next generation of dense wireless mobile networks.

Solution:

like MPIPv6 but with SDN. Local controller (CROWN LC) and Regional Controller (CRC). Node attached to AP1. CLC1 establish flow to GW1 and assign IPv6 prefix to MN and update CRC. When MN move to AP2, CLC2 ask CRC for presence history. CLC2 then builts tunnel between GW2 and GW1 allowing on going flows, sessions for MN travel through GW1 to GW2.

Possible improvement:

• Move session from PoP1 to PoP2, no flow routing. Useful when group communication, D2D. Local cache.
• Service mobility, service aware.
• CCN usecase implementation.

  Empowering Software Defined Wireless Networks Through Media Independent Handover Management

Contribution:

Bringing SDN to Wireless, real deployment. This is where this paper contributes, by presenting a framework where SDN-based mechanisms, in the form of the OpenFlow protocol, are used to configure the wireless net- working nodes and establish communication paths. We explore Media Independent Handover (MIH) procedures, from the IEEE 802.21 standard, to optimize handovers in heterogeneous wireless environments. This approach goes beyond current efforts of integrating OpenFlow with wireless capabilities, that only target the extension of experimental testbed into wireless experimentation. Here, we present how SDN can actually be used to support wireless communication paths, with dynamic mobility management capabilities provided by standards com- pliant nodes. Results show that this combination allows the provision of enhanced connectivity scenarios, allowing Always Best Connectivity when different handover candidates are presented, and triggering OpenFlow procedures preemptively in order to avoid traffic disruption.

Solution:

Framework with sdn controller, OVS AP, MN. Signal shifting scenario, where pre-emptive flow setup on candidate PoA. Both update link status with controller.

OpenRoads [3] is the first successfully deployed pro- grammable SDN-based WLAN architecture for testing various WLAN algorithms. It is a layer based architecture, namely a physical layer, a network virtualization/slicing layer and a controller layer. It discussed about how the OpenFlow [5] can be used by wireless researchers for performing hand- off between different wireless technologies. CloudMAC [6] is a data center based management architecture in which APs just forward MAC frames. Other functions such as processing MAC frames are implemented on standard servers of the data center. SDN architectures are also helpful for Wireless Mesh Networks (WMNs). OpenFlow based WMN architectures help in design of flexible packet routing algorithms for WMNs. In [7], the authors demonstrated usefulness of OpenFlow based WMN system for enabling client mobility to achieve fast handovers at low complexity and overhead. ODIN is a programmable WLAN architecture [4] for sim- plifying association decisions of clients in enterprise WLANs. It provides a basic framework for designing various WLAN management algorithms at the SDN controller. Thanks to ODIN [4] architecture for its open source [8] support, in this work we extend it further for offering load-aware hand-offs in enterprise WLANs.

In this paper, we propose several designs for SDN-based Mobile Cloud architectures, focusing on Ad hoc networks. We present the required core components to build SDN-based Mobile Cloud, including variations that are required to accommodate different wireless environments, such as mobility and unreliable wireless link conditions. We also introduce several instances of the proposed architectures based on frequency selection of wireless transmission that are designed around different use cases of SON­ based Mobile Cloud. We demonstrate the feasibility of our architecture by implementing SDN-based routing in the mobile cloud and comparing it with traditional Mobile Ad Hoc Network (MANET) routing. The feasibility of our architecture is shown by achieving high packet delivery ratio with acceptable overhead.
