In Next Generation Wireless Networks (NGWN), lots of information, such as voice and video data, will be used in All-IP networks. It is important to note that in such environments, seamless service for users and handoff between heterogeneous networks must be taken into account. Therefore, in this paper, we propose a SePH (Seamless Proxy based Handoff) using(More)
In this paper, a mobility-aware Dual Pointer Forwarding scheme (mDPF) is applied in Proxy Mobile IPv6 (PMIPv6) networks. The movement of a Mobile Node (MN) is classified as intra-domain and inter-domain handoff. When the MN moves, this scheme can reduce the high signaling overhead for intra-handoff/inter-handoff, because the Local Mobility Anchor (LMA) and(More)
The mobile Virtual Private Network (MVPN) of the Internet Engineering Task Force (IETF) is not designed to support NEtwork MObility (NEMO) and is not suitable for real-time applications. Therefore, architecture and protocols to support VPN in NEMO are needed. In this paper, we propose a cost-effective and secure mobility management scheme (SeSIP) that is(More)
