Mobility support in IPv6 networks (MIPv6) and Fast Handovers for Mobile IPv6 (FMIPv6) are already released as RFCs for many years. While the former focuses on maintaining the network connections when a mobile node handovers across subnets, the latter is built based on the former concept, but focuses on reducing the packet loss and latency inherent to the handover process. Performance study of both...
SCTP faces three performance problems in hard handover scenarios: high network handover delay, high transport handover delay and throughput under-utilization. Existing solutions assume the mobile extension of SCTP (m-SCTP) as a unique way to handle handovers and rely on terminal mechanisms. Nevertheless, they are not efficient as they lack the necessary information to perform on-time and fine SCTP...
Considering lack of comparative studies on Ping-pong movement, comprehensive evaluations were carried out to estimate the impact of layer-3 handoff latency on End-to-End TCP for mobile IPv6 and its extensions. Results show that FHMIPv6, which has 273ms overall handoff delay, 93.867 Kbytes/s average goodput and 9.125% packet loss rate, performs better than HMIPv6 and FMIPv6 frameworks under Ping-pong...
At present, the number of Internet subscribers accessing Internet through mobility terminal equipment and other new types is gradually increasing, which shows it's important to develop mobility management protocols in order to provide mobility support for the subscribers. Several protocols were proposed to support IP mobility in the IETF, such as MIPv6, HMIPv6, FMIPv6 and F-HMIPv6. Some performance...
Mobility management solutions designed for heterogeneous networks can provide seamless handover and service continuity. Thus, ongoing TCP sessions can remain active, even when mobile node handovers from one access network to another. In such seamless handover, packet loss can be avoided but TCP still undergoes through several performances degradation issues due to change of network characteristics...
3G networks provide access to network mobile users at multiple data rates. The lack of mobility support for mobile nodes, by the standard protocols originally developed to meet the requirements of stationary nodes in wired networks, implies that these standard protocols cannot be efficiently implemented in wireless networks. Transmission Control Protocol (TCP) considers packet losses during Vertical...
Using the application of bluck data transfer, we investigate the performance of QoS-satisfied pathover for transport layer mobility scheme such as mSCTP in FMIPv6 envirmonment. We find that existing scheme has some defects in aspect of pathover and throughput. Based on this, we make a potential change to mSCTP by adding QoS-Measurement-Chunk, which is used to take into account information about wireless...
The mobile Stream Control Transmission Protocol (mSCTP) can be used to support IP handover. This paper proposes an extension of mSCTP with bicasting for vertical handover across heterogeneous wireless access networks, in which the data packets of mSCTP are bicast to the old and new IP addresses in the vertical handover region. From the ns-2 simulation results, it is shown that the proposed scheme...
Mobile IP technology is one of the important supporting technical in the construction of pervasive computing environment. However, the existing literatures lack a comprehensive, systematic research and analysis for handover performance of mobile IPv6 based ping-pong mode. This paper gives a comprehensive evaluation of the L3 handover performance of a variety of mobile IPv6 extension protocols based...
