This paper proposes an enhanced handover scheme of the Proxy Mobile IPv6 (PMIPv6) with partial bicasting in wireless networks. In the proposed PMIPv6 handover scheme, when a mobile node (MN) moves into a new network and thus its Mobile Access Gateway (MAG) performs the binding update to the Local Mobility Anchor (LMA), the LMA begins the `partial' bicasting of data packets to the new MAG as well as...
This paper addresses the multicast handover in the wireless networks based on the Proxy Mobile IPv6 (PMIP). The existing PMIP-based multicast schemes tend to induce severe packet losses, large handover delays and unnecessary data transmissions during handover. To overcome these problems, we propose the use of Multicast Handover Agent (MHA) for fast handover. In the proposed scheme, called PMIP-MHA,...
This paper presents the implementation scheme of MIPv6 protocol and improvement of key technology based on Adhoc network in Linux. The framework of implementing MIPv6 protocol is designed. The key technology of protocol implementation procedure is proposed, and the handover delay of mobility is analyzed and reduced. Finally experimental scenarios are set up, and the performance of mobile handover...
Network layer indications are not readily available upon a link change; therefore, general dependence on the network layer may introduce unnecessary delays due to network layer signaling for a simple link layer handover. If information could be gathered at link layer to determine the need for network layer signaling, then both the delay and signaling load could be really improved over the current...
In the MPLS-based mobile IPv6 network, when mobile node performs handover, it needs to rebuild label switching path, which impacts the handover delay and causes packets loss. Reused parts of the path overcome the above reasons, which propose a cross-router (CR) algorithm. It modifies the label information base (LIB), that is, increases two fields: the mobile node address and the time counter. When...
The aim of this article is to present a novel handover algorithm to decrease the handoff latency in all-IP based future heterogeneous mobile communication system (FHMCS). The reduction in handoff latency is achieved by employing mobile network discovery technique which will decrease the delays due to movement detection, new care of address configuration and duplicate address detection (DAD). The decrease...
Providing a seamless handoff and quality of service (QoS) guarantees is one of the key issues in real-time services. Several IPv6 mobility management schemes have been proposed and can provide uninterrupted service. However, these schemes either have synchronization issues or introduce signaling overhead and high packet loss rate. This paper presents a scheme that reduces the handoff latency based...
Multi-homing is increasingly being employed by large enterprises to extract good performance and reliability from their connections. The integration of existing and emerging heterogeneous wireless networks requires the design of intelligent failure detection and recovery schemes to enable mobile users to switch between networks and experience uninterrupted service continuity anywhere, anytime. Real...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
