Hierarchical MIPv6 (HMIPv6) is proposed to improve the system performance of mobile IPv6 (MIPv6). However, HMIPv6 cannot outperform MIPv6 in all scenarios because of its double-registration when a user roams across regions and the longer packet delivery latency. Therefore, to select a proper mobility management scheme between MIPv6 and HMIPv6 becomes an interesting issue, for its potentials in enhancing...
Next generation wireless networks are envisaged to be an integration of heterogeneous but complementary wireless access networks. The inter-networking of these heterogeneous wireless networks with the Internet will provide ubiquitous access to roaming network users. However, a seamless handover mechanism with negligible handover delay is required to maintain active connections during roaming across...
This paper proposes solutions for the trusted connection between mobile nodes and mobility anchor points in hierarchical mobile IPv6. Two operation modes are supported for different scenarios: The first one is authentication-only mode for the scenario that the mobility anchor point only needs to ensure any binding update messages are from the claimed mobile nodes. The second one is authentication...
Future generations of mobile operator networks, based on an all-IP-based flat architecture and a multitude of different access technologies, require a proper IP-based mobility management in place. In this article, a scalable and completely distributed mobility management is presented which is based on a Distributed Hash Table data structure. The Distributed IP Mobility Approach (DIMA) remains completely...
Mobile IP allows a mobile node to maintain a continuous connectivity to the Internet when moving from one access point to another. However, due to the link switching delay and to the Mobile IP handover operations, packets designated to mobile nodes can be delayed or lost during the handover period. This paper presents a new control function called Extended Handover Control Function (E-HCF) in order...
Multi-protocol label switching (MPLS) is deployed in the Internet backbone to support service differentiation and traffic engineering. Mobile MPLS is a new scheme that integrates Mobile IP and MPLS protocols to support mobility to MPLS. However, it is not suitable for micro-mobility environments. In this paper we propose a micro-mobility architecture based on the integration of MPLS for wireless networks...
Fast handover protocol provides seamless handover in mobile IPv6 networks by reducing handover latency. One assumption in fast handover is that the MN (Mobile Node) or the network could know or predict the new AR (Access Router) before data transport from the previous AR to the MN is disrupted. In order to achieve this capability, the complexity of predicting the new AR and the diversity of the wireless...
In recent years, mobile network has evolved greatly with the existences of MANET, wireless sensor network, mobile IP, NEMO and etc. The advent of network mobility (NEMO) tends to provide seamless Internet connectivity to all the nodes within a mobile network regardless of their current points of attachment with the usage of a mobile router. Multicasting support is one of the key technologies in next...
Mobile IPv6 (MIPv6) protocol is a new protocol designed to support the node mobility of IPv6 protocol, which is a basic protocol of the next generation Internet. Protocol testing consists of conformance testing, interoperability testing and performance testing. Protocol emulation testing, which we adopt in this paper, is a way of protocol testing. This paper designs an emulation-based method for performance...
In this paper, we use the OMNET++ simulator in order to evaluate the performance of the basic mobile IPv6 protocol and some of its proposed variations. The most important metric we are interested in is the handover latency, which is measured for various combinations of the proposed mobile IPv6 variations and then this metric is used, combined with factors such as the complexity of the implementation,...
This paper investigates differentiated services in heterogeneous mobile IP networks using a distributed method that supports service differentiation and admission control. Mobility and quality of service (QoS) are becoming more important issues in mobile networks. It is general that the traditional Internet service provides the same level of service to all users. However, new type of services demand...
Multicast is an efficient method to transmit datagrams in the Internet. In this paper, we provide a multicast algorithm in a network mobility (NEMO) environment. We propose the mobile router forwarding scheme (MRFS) algorithm. There are two advantages in the MRFS algorithm. First, MRFS reduces the storages in every MR especially in the TLMR (top level MR). Second, MRFS transmits multicast datagrams...
This paper proposes an extension to Fast-handover Mobile IPv6 [6] that improves handover latency in Mobile IPv6 procedures in case mobile nodes have multiple wireless interfaces. In the basic Fast MIPv6 [6], a previous access router (PAR) forwards arriving packets for the mobile node to a new access router (NAR) by setting up a tunnel to the NAR in order to prevent packet losses incurred by latency...
The need for mobility, autonomy, permanent access to information and mobile computing are some of the realities of today's communication society. Considering the wide area of communication technologies, the convergence of different types of networks (WiFi, GSM/UMTS, Satellite etc.) represents the solution for the achievement of the "whenever and wherever" paradigm, that is one of the objectives...
In this paper we propose an enhanced MIPv4 fast horizontal handover scheme using IEEE 802.21 Media Independent Handover (MIH). This scheme enhances the L3 handover decision algorithm based on MIH provided information of available bandwidth and physical distance and minimizes L2 handover time. The handover decision algorithm is considering the overall sequence using MIHF, and based on Quality of Service...
Nowadays, most firewalls which are deployed in networks are not compatible with mobile IPv6. And to modify the configuration of firewall by using NSIS signaling is one of signaling solutions. In this paper, the purpose is to resolve the problems which are in mobile IPv6 network environment during the traversal process by using NSIS signaling. We introduce a new method that can reduce the complexity...
Recently, a network-based mobility management protocol called Proxy Mobile IPv6 (PMIPv6) is being actively standardized by the IETF NETLMM working group, and is starting to attract considerable attention among the telecommunication and Internet communities. Unlike the various existing protocols for IP mobility management such as Mobile IPv6 (MIPv6), which are host-based approaches, a network-based...
The development of network technologies such as wireless LAN have made it possible for users to benefit from Internet connectivity almost anywhere and at anytime. In order to improve user experience, the IETF has defined the Mobile IPv6 protocol which allows mobile nodes to maintain their communication uninterrupted while roaming across various IPv6 subnets. However, the mechanisms this protocol defines...
Supporting for mobile node communications, lots of technologies are researched. They are categorized as infrastructure and infrastructureless : Mobile IP and ad hoc network. Basically, the ad hoc technology is able to the mobile nodes data exchanging within closed group communication. However due to the desire of open network connectivity, the ad hoc networks researches are extended to Internet connective...
Mobile nodes moving across heterogenous access networks need to perform mobile IP handovers to maintain continuity of Internet access. The IEEE 802.21 framework was defined to support such handovers by providing link layer intelligence and media independent handover control facilities to the user entities. This framework, however, does not provide all controls necessary to perform seamless handovers...
