“…FPMIPv6 [13] reduces the handover latency and packet loss considerably but involves the MN in the control signaling which violates the fundamental concept of PMIPv6. Smart buffering [14] reduces the packet loss on the expense of control signaling; however handover delay remains same as PMIPv6 which causes huge buffering cost.…”

“…A lot of schemes have been proposed to reduce this latency [11][12] [13]. Some schemes involve mobile nodes (MN) in the handover procedure [14], which does not conform to the fundamental concept of PMIPv6, or a network based mobility management protocol. Most of the schemes considerably reduce the latency in PMIPv6 but at the cost of computationally intensive algorithms, which predict and manage handovers.…”

Mobility management in wireless networks has been one of the hot research areas in the last decade. PMIPv6 is a network-based layer 3 mobility management protocol, standardized by IETF. It is considered as a promising solution for resolving issues related to the layer 3 mobility management. However, handover latency in PMIPv6 is not acceptable for real time applications. In this paper we introduce OF-PMIPv6; in which OpenFlow controller takes care of all the control signaling and mobility algorithms on the behalf of Mobile Access Gateway (MAG). This results in a simpler MAG with reduced handover latency. OpenFlow is a standard which runs on network devices (e.g. switches, routers etc.) and enable them to communicate with a central server (OF controller). In OF-PMIPv6, the MAGs preform control signaling with LMA through the OpenFlow controller, whereas data communication takes place directly between the MAG and LMA. In this paper we present the detailed architecture of OF-PMIPv6 and proactive handover scheme. Towards the end, analytical analysis based comparison of handover latency in PMIPv6 and proposed OF-PMIPv6 is presented.

“…Jeon et al [12] have proposed a solution of two-phase tunnel control based on the IEEE 802.21 to handle early packet forwarding problem in the FPMIPv6. Smart buffering [4] reduces the packet loss on the expense of control signaling and extra memory requirement; however handover de- lay remains same as the standard PMIPv6. Kim et al [2] proposed a solution to mitigate the packet loss during the handover in PMIPv6 by introducing a buffering mechanism at the anchor, requiring larger buffering space at the anchor to cater the needs of all the mobile nodes for a large scale network.…”

“…Other pure network based proposed schemes reduce the handover delay and packet loss to great extent. The limitations that current schemes incur are, high bandwidth requirement due to of excessive control signaling; and intense computation intensity either on the gateway or on the anchor [3], [4]. These limitations result in higher operational cost and pose major hurdle in deployment of these schemes in realistic scenarios.…”

Abstract:The existing Proxy Mobile IPv6 suffers from a long handover latency which in turn causes significant packet loss that is unacceptable for seamless realtime services such as multimedia streaming. This paper proposes an OpenFlow-enabled proxy mobile IPv6 (OF-PMIPv6) in which the control of access gateways is centralized at an OpenFlow controller of a foreign network. The proposed OF-PMIPv6 separates the control path from the data path by performing the mobility control at the controller, whereas the data path remains direct between a mobile access gateway and a local mobility anchor in an IP tunnel form. A group of simple OpenFlow-enabled access gateways performs link-layer control and monitoring activities to support a comprehensive mobility of mobile nodes, and communicates with the controller through the standard OpenFlow protocol. The controller performs networklayer mobility control on behalf of mobile access gateways and communicates with the local mobility anchor in the Proxy Mobile IPv6 domain. Benefiting from the centralized view and information, the controller caches the authentication and configuration information and reuses it to significantly reduce the handover latency. An analytical analysis of the proposed OF-PMIPv6 reactive and proactive handover schemes shows 43% and 121% reduction in the handover latency, respectively, for highly utilized network. The results gathered from the OF-PMIPv6 testbed suggest similar performance improvements.Index Terms: IP mobility, OpenFlow, proxy mobile IPv6 (PMIPv6), software defined networks (SDN).

Next generation wireless networks (NGWN) will be an integration of heterogeneous wireless access networks that will interwork over an IP-based infrastructure. This all-IP vision has led to the development of handover mechanisms to support seamless mobility for active network services among the different interworking wireless networks in order to ensure network access ubiquity in NGWN. These handover mechanisms need to ensure that mobile devices continue to receive ongoing communication without any noticeable disruption during handover events among the heterogeneous networks. This paper gives a qualitative and quantitative review of current handover approaches of IP mobility management protocols for NGWN with an objective to introduce a new way of further optimizing the handover performance. In particular, the paper focuses on handover approaches of mobile IPv6 (MIPv6) based mobility management protocols. Thus, the need, benefits, and limitations of these handover approaches are explored. Thereafter, dynamic handover coordination is introduced as a new viable solution that exploits the benefits and mitigates the limitations of these handover approaches hence improving handover performance in terms of handover delay, packet loss, and signaling overhead.Notably though is that the movement detection signaling is exchanged between the MH and the MAP as opposed to MH and AR as is the case in FMIPv6 and HMIPv6, hence the delays encountered are different. MIPV6 RELATED NETWORK-BASED MOBILITY MANAGEMENT PROTOCOLSContrary to host-based mobility management protocols, in network-based mobility management the MH is not involved in any mobility-related signaling. In fact, a network element or proxy agent performs all the mobilityrelated signaling on behalf of the MH. The most common L. A. Magagula et al.Seamless mobility management
