Proxy Mobile IPv6 (PMIPv6) has been developed by the IETF as a network-based mobility management protocol to support the mobility of IP devices. Although several proposals have been made for localized routing optimization, they don't take into account handover management and localized routing simultaneously. In fact, the localized routing state is only(More)
While there have been tremendous efforts to develop the architecture and protocols to support advanced Internet-based services over 3G and 4G networks, IMS is far from being deployed in a wide scale manner. Effort to create an operator controlled signaling infrastructure using IP-based protocols has resulted in a large number of functional components and(More)
With the increasing demand for quality of service (QoS) by end-users, mobility management, IP flow mobility and data offload are key features needed in next-generation wireless networks. With the wide deployment of WiFi (e.g., home, vehicle, smartphones, laptops) and onboard unit (OBU) in automotive and public transportation systems (PTS), it is important(More)
Next generation wireless networks (NGWN) or 4G are envisioned to be a combination of different architectures and wireless technologies. This brings several design and deployment challenges, such as mobility management, quality of service (QoS) provision and networks interworking. Mobile IPv6 (MIPv6) and its extensions, like HMIPv6 and FMIPv6, have been(More)
