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(More)
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(More)
Proxy Mobile IPv6 (PMIPv6) is an IP mobility protocol. In a PMIPv6 domain, local mobility anchor is involved in control as well as data communication. To ease the load on a mobility anchor and avoid single point of failure, the PMIPv6 standard provides the opportunity of having multiple mobility anchors. In this paper, we propose a Software Defined(More)
The communication industry is envisioning ubiquitous connectivity as a crucial driving force in 5G. Next Generation Network (NGN) should interconnect, integrate and efficiently manage the enterprise networks to realize this vision. Efficient management and an always-on connectivity with seamless mobility across multiple radio access technologies are the(More)
With LTE already in the deployment phase and LTE-A knocking on the door, proposals and research groups for the 5G networks have started to surface. There are no formal specifications or standards for the 5G networks yet. In many recent proposals, people have proposed 5G as a network which provides interoperability among the heterogeneous wireless networks.(More)
Research on future 5G networks has geared up in the past couple of years, and among many other, seamless mobility is considered as a cornerstone of 5G networks. Lately, many mobility solutions have been put forward, among them are Software Defined Networking (SDN) based Proxy Mobile IPv6 (PMIPv6) and Distributed Mobility Management (DMM). SDN-PMIP advocates(More)
Software defined network (SDN) enables network programmability and provides fine grained control for managing the complex network infrastructure. With the centralized nature of SDN it poses the requirement for failure management at the data plane, control plane and at the centralized controller side. The self-healing attribute of the autonomic network can(More)
