Technological developments alongside VLSI achievements enable mobile devices to be equipped with multiple radio interfaces which is known as multihoming. On the other hand, the combination of various wireless access technologies, known as Next Generation Wireless Networks (NGWNs) has been introduced to provide continuous connection to mobile devices in any time and location. Cognitive radio networks...
4G networks or the future generation networks are heterogeneous networks. Different technologies converge over the IPv6 core and provide different services to the user nodes. Handover Management in 4G network is an issue that requires attention. The Internet Engineering Task Force have proposed varied protocols for mobility management. The existing protocols for handover management do not consider...
Proxy Mobile IPv6 (PMIPv6) takes advantage of the network-based mobility management that provides mobility support for moving nodes (MNs) without their involvement. However, the main drawback of PMIPv6 is that the inter-domain handover is not supported. That means when an MN moves to another PMIPv6 domain, the on-going sessions cannot be maintained. Although several proposals have been introduced...
Low handover latency and IP session continuity are envisioned to be important factors for realizing next-generation all-IP heterogeneous wireless networks. To meet these constraints of the next generation networks, Proxy Mobile IPv6 (PMIPv6) has been considered as one of the IP mobility management protocols in recent years. Much research about the performance analysis of PMIPv6 has been done. However,...
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...
In next generation mobile networks where heterogeneous but complementary wireless networks will coexist and combine resources to provide ubiquitous access to internet services, vertical handover needs to be executed seamlessly to ensure that active service sessions are not disrupted during mobility events. Seamless handover, which should be non-perceptible to the mobile user, can be experienced if...
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...
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...
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...
The future generation wireless systems target to provide users with high-speed Internet access and multimedia services besides voice. Mobile IP was developed to provide the freedom of mobility to the users with continuous network access. MIPv6 is the grown up version of Mobile IP and eliminates the problem associated with address space of IPv4 and gives extra bit of inherent security (IPSec). To minimize...
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)...
