Proxy Mobile IPv6 outperforms previous mobility protocols have been standardized by the Internet Engineering Task Force. However, Proxy Mobile IPv6 still involves the triangle routing problem in where data packets for the mobile node are delivered throughout inefficient routing paths. To address the triangle routing problem, two different Route Optimization schemes proposed that exclude the ine...

This paper addresses the Proxy Mobile IPv6 (PMIP) handover using bicasting in mobile/wireless networks. The bicasting scheme can be used to support the PMIP handover, which tends to waste the network resources of wireless links and incurs data losses during handover. We propose an enhanced scheme of PMIP handover, called the partial bicasting with buffering for PMIP (PBB-PMIP). In the PBB-PMIP ...

IP based wireless mobile networks are of great importance now-a-days to users on the move. To provide connectivity to mobile users with same IP address despite of their change in location or point of attachment, the location information of mobile users must be kept up to date. Managing location information of such users basically needs information to be exchanged between different network entit...

Proxy Mobile IPv6 is a promising protocol for supporting mobility. Unlike Mobile IPv6, which is based on hostmobility, the Proxy Mobile IPv6 is based on network-based mobility so that it can remove additional implementations on a Mobile Node (MN). Due to this feature, Proxy Mobile IPv6 has been considered as a better protocol than Mobile IPv6 in supporting mobility. However, PMIPv6 still has a ...

In this paper, we propose and analyze DMAP-FR, a mobility and service management scheme with failure recovery (FR) control in Mobile IPv6 systems. The basic idea behind DMAP-FR is to leverage access routers (ARs) running as regional mobility anchor points (MAPs) as in Hierarchical Mobile IPv6 (HMIPv6) for mobility and service management formobile nodes (MNs). However, unlikeHMIPv6,DMAP-FR allow...
