This paper describes a framework of mSCTP handover in the crossover mobility patterns and analyzes the handover latency for the MN. We see that the throughout of the data transmission could be degraded, as the crossover movements occur more frequently. We use MIP and it can record some parameter and mSCTP will not establish connection again, so it will improve transmission performance. More importantly,...
Abstract: According to the mobility support characteristics and demands in the Identifier/Locator separation mapping network and aiming at the switching delay problem in the existing mobile switching technology, a seamless switching method based on reverse routing redirection is proposed in this paper. This method consists of the mobility detection, mapping information update and flow deflection,...
Wireless Sensor Network (WSN) technology is being increasingly adopted in a wide variety of applications ranging from home/building and industrial automation to more safety critical applications including e-health or infrastructure monitoring. Considering mobility in the above application scenarios actually introduces additional technological challenges, especially with respect to security. The resource...
Hierarchical Mobile IPv6 (HMIPv6) introduces a mobility anchor point (MAP) that localizes the signaling traffic and hence reduces the handoff latency. In addition to processing binding update messages from mobile nodes (MNs) on behalf of MNs' home agents (HAs), the MAP performs data traffic tunneling destined to or originated from MNs, both of which will burden the MAP substantially as the network...
Hierarchical Mobile IPv6 (HMIPv6) introduced by IETF to enhance mobility problem in the next generation Internet Protocol (IPv6). The key concept behind HMIPv6 is the usage of Mobility Anchor Point (MAP) located at any level in a hierarchical network to support micro-mobility management and seamless handover. Therefore the furthest MAP selection in HMIPv6 can be a MAP overload and increases frequent...
In IP-based wireless/mobile networks, mobility support is one of the most critical issues. Hierarchical Mobile IPv6 (HMIPv6) was proposed by Internet Engineering Task Force (IETF) to mitigate the high signaling overhead in Mobile IPv6 networks when mobile nodes (MNs) perform frequent hand-offs. Although the standardization process of the HMIPv6 specification has been almost completed in IETF, there...
Information-Centric Networking (ICN) is constantly gaining momentum within the Future Internet research community. In the PURSUIT research project we are developing a clean-slate Pub/Sub Internetworking (PSI or Ψ) approach with integrated seamless mobility support. The novel ICN mechanisms supported in Ψ, along with smartly placed in-network caches, enable the architecture to handle both mobile and...
This The duration of a standard MIPv6 (Mobile IPv6)handover process is relatively long for many real-time sensitive applications. Many earlier proposed solutions of this problem aim on reducing the duration of the address registration and configuration processes during a handover. There are only few paper intended to shorten the DAD (Duplicate Address Detection) process in a MIPv6 handover. In this...
Seamless IP-diversity based NEtwork MObility (SINEMO) was proposed to address a number of drawbacks of the Network Mobility (NEMO) protocol for mobility management of a number of hosts moving together in a Local Area Network. Increasing number of mobile hosts results in higher level of signalling cost on the mobility agents in a mobility protocol. Previous works on cost analysis of mobility protocols...
With the large number of access technologies and the emergence of user mobility, the need to "access the world", anywhere and anytime has gained a significant importance. It is essential to ensure the quality of the services when moving between access networks and technologies in a transparent manner. This paper presents a new architecture that enables seamless handovers in wireless heterogeneous...
The need for Quality of Service (QoS) capabilities in the Internet originates from the fact that Best-Effort service and datagram routing do not meet up the desires of many new applications. Video conferencing, voice over IP (VoIP), and video on demand (VoD) are examples of real-time applications. These applications require some degree of resource assurance in order to operate effectively. Vast and...
To improve handoff performance of the network-based Proxy Mobile IPv6 (PMIPv6), two types of enhanced handoff schemes have been presented; fast handover for PMIPv6 (F-PMIPv6) and route optimization handover (ROH). The F-PMIPv6 is committed to reduce handoff latency and is efficient to perform handoff signaling. However, it causes high packet delivery cost from additional tunneling at the LMA. The...
Cellular networks coupled with wireless local area networks would be very common in the next- generation wireless environments. This integration would be made possible by employing techniques of vertical handover across different radio access networks. Finding precise timing to carry out vertical handover is an important problem and is the topic of this research work. We propose a hybrid vertical...
The overall performance of hybrid ad hoc networks, which is the integration of ad hoc networks and fixed IP networks like the Internet is affected heavily by the discovery and selection of Internet gateways. Each of existing proposals is suited only for a limited range of network conditions and its performance can vary dramatically as the network conditions change. The obvious unidirectional links...
Mobile IPv6 (MIPv6) is a host-based mobility management protocol that provides continuous service for mobile nodes (MNs) when they change their attachment points. However, MIPv6 is not suitable for real-time services because it causes long disruptions during handoff. Recently, the IETF NETLMM working group proposed a network-based localized mobility management protocol, called Proxy Mobile IPv6 (PMIPv6)...
Mobile IPv6 (MIPv6) was developed by the Internet Engineering Task Force to support the mobility service as wireless technologies have grown and many people are more and more using wireless networks during movements. MIPv6 has long been favored over Mobile IPv4 and it's a major solution to supply mobility services on the Internet and therefore it's proposed for the future of the mobile Internet access...
Supporting flow mobility is an emerging challenge in today mobile networks. This paper introduces a network-based solution to support flow mobility. It requires minimum modification at the mobile node. All signaling processes are performed by the network. The mobile node can seamlessly switch flow over multiple access technologies while maintaining ongoing connections.
An integrated heterogeneous wireless system (IHWS) combines different wireless access technologies together and provides a user with ubiquitous network connectivity. Security in such network is extremely critical for its successful implementation. However, each underlying network in an IHWS has a unique security scheme that cannot be adopted by other networks. Several security algorithms that have...
In this paper we propose an improved hierarchy based mobility management scheme THMIP (Three-level Hierarchical Mobile IP) using fluid flow model to reduce the signaling overhead for a frequently moving mobile node (MN) within its hierarchical domain. In this scheme, the MN sends the binding update to the Home Agent (HA) only for the first time when the Care of address (CoA) gets changed. From the...
Numerous researches about Mobile IPv6 (MIPv6) have been proposed recently and the handover delay of the Mobile Nodes (MNs) among different networks is surely a worthy noticing issue. There are three major reasons for the MIPv6 handover delay: Movement Detection, Duplicate Address Detection (DAD), and Binding Update (BU), in, which DAD occupies most of the MIPv6 handover delay and influences real-time...
