Internet mobility protocols are designed to support handover between different wireless networks. Many of them, such as Mobile IPv6, suffer problems such as high handover latency, high packet overhead, high packet loss during handoff, requirement for infrastructure change, etc. To solve these problems, SEamless MObility using SHIM6 (SEMO6), a multihoming based mobility protocol framework for host...
Mobile IPv6 (MIPv6) and its basic extension for network mobility NEMO were initially designed to manage the mobility of device users and networks respectively while maintaining a permanent IP address. Nevertheless, the different MIPv6's experiments have shown many lacks in case of high mobility of nodes such as in vehicular networks. To overcome these lacks, many solutions have been proposed by the...
Proxy Mobile IPv6 has been developed as a network-based mobility management protocol. This new protocol enables a mobile node to change its point of attachment without its own mobility signaling. That is, network entities provide the mobility service for the mobile node. In this paper, we introduce a new handover process designed for improving handover performance in terms of handover latency. The...
With the rapid developments and convergence in the communication and personal computing technology fields, the overall quality of ubiquitous communication has improved significantly. This is especially true with invention of portable mobile devices that can be connected almost everywhere at any time. However, the recent explosion on the usage of mobile devices has also generated several issues in...
The mobility support protocols are separated by two categories; First, Host-based mobility management protocols such as Mobile IPv6, and its enhancements (HMIPv6 and FMIPv6) which all basically requires protocol stack modification of the mobile node in order to support them. That modification may increase the complexity on them and wasting of air resource. Besides, some drawbacks that still suffers...
Handover latency in mobile IPv6 plays an important role in the performance of a given network scenario. It results in packet losses and severe end-to-end performance degradation due to throttling and retransmissions in TCP scenario. This paper presents a comparative study of some different mobility management scheme for reducing handover latency and packet loss in mobile IPv6 environment. We describe...
Mobility protocols are designed to support handover between different wireless networks. Many of them suffer problems such as high handover latency, high packet overhead, high packet loss during handoff, lack of application transparency, etc. To remove these problems, we proposed a network layer based mobility protocol framework, SEamless MObility using shim6 (SEMO6), for host mobility. It is based...
Mobile IPv6 (MIPv6) is a presentative protocol which supports global IP mobility. MIPv6 causes a long handover latency that a mobile node (MN) doesnpsilat send or receive packets. This latency can be reduced by using Proxy Mobile IPv6 (PMIPv6). PMIPv6 is a protocol which network supports IP mobility without participation of the MN, and is studied in Network-based Localized Mobility Management (NETLMM)...
