Multihomed mobile network architecture
IP mobility ensures network reachability and session continuity while IPv6 networks are on the move. In the Network Mobility (NEMO) model, the potential for NEMO Mobile Routers (MRs) to interconnect and extend Internet connectivity allows the formation Nested NEMO networks. With MANEMO, nested MRs can be efficiently interconnected in a tree-based structure with Internet access being maintained via a designated Gateway. However, this only supports single-homed Internet connectivity. With the span of wireless access technologies and the popularity of multi-interfaced devices, multihoming support in this scenario becomes critical. A Nested Mobile Network with heterogeneous available Internet access options would allow better overall network performance and optimal utilisation of available resources. In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed mobility solution. It provides a multihoming management mechanism for Gateway Discovery and Selection on top of a multihomed mobility model integrating different mobility and multihoming protocols. It enables a complex nested multihomed topology to be established with multiple gateways supporting heterogeneous Internet access. The results demonstrate that the proposed solution achieves better overall throughput, load sharing, and link failure recovery
Mobility through Heterogeneous Networks in a 4G Environment
Serving and Managing users in a heterogeneous environment. 17th WWRF Meeting in Heidelberg, Germany, 15 - 17 November 2006. [Proceeding presented at WG3 - Co-operative and Ad-hoc Networks]The increase will of ubiquitous access of the users to the requested services points towards the integration of heterogeneous networks. In this sense, a user shall be able to access its services through different access technologies, such as WLAN, Wimax, UMTS and DVB technologies, from the same or different network operators, and to seamless move between different networks with active communications. In this paper we propose a mobility architecture able to support this users’ ubiquitous access and seamless movement, while simultaneously bringing a large flexibility to access network operators
Towards an architecture to support complex multihomed mobility scenarios
In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed mobility solution for complex nested mobility scenarios. It provides a multihoming management mechanism for gateway discovery and selection, on top of an efficient multihomed mobility model integrating different mobility and multihoming protocols. We describe how the MMNA was experimentally implemented and evaluated in a testbed setup. We first validated the capabilities of the solution in terms of different multihoming features, namely load sharing, link failure recovery, and preference setting. We then examined the effectiveness and feasibility of the MMNA solution considering a use case example of a search and rescue scenario. The results highlight the practicality and advantages of deploying the MMNA solution into realistic scenarios
Enhanced Mobility Solution In Mobile Ipv6 Network
The performance of Network Mobility (NEMO) used to manage network mobility does
not provide satisfactory result in terms of delay, throughput and session continuity when
dealing with multihomed mobile network. Enhanced Mobility Solution in Mobile IPv6
Network is extremely complex; the study addressed the multihoming issues of MIPV6
Networks on the basis of NEMO Basic Support, analyzes the benefits of multihoming
and discusses implementation issues of all classes of multihoming possibilities.
Additionally, Policy-based routing, as one of the multihoming benefits, is studied in
particular.
A framework based on policy based routing protocol was proposed for handling both the
inbound and the outbound traffic on a mobile network, under specified policies which
consider packet characteristics, current network situation and user preferences. The
interface selection algorithm was based on NEMO implementation structure using a
technique of mutihoming which was extended to MIPv6 concepts The outcome of this research work are: a designed policy protocol for policy messages
communication between the Mobile Router and the Home Agent, the framework is
simulated using Network Simulator (NS2) with an extension of mobiwan, the result
shows the end to end delay, average end to end delay, overhead, optimal routing path,
average inter-packet latency and throughput of the developed system. The information
from the analysis of the result shows that the enhanced solution has drastically reduced
average packet delay to minimum with 72.5 %( 0.040s to 0.011s), and end-end delay with
75 %( 0.020s to 0.005s) compared with NEMO solution. Overhead in the mobile network
was maintained by 10bytes per nested level by keeping the session.
The solution is important by enterprises in making decision to acquire internet
connectivity for the purpose of connectivity redundancy and traffic load distribution
optimization. This result is very important for time sensitive application that requires
stable network condition
Efficient mobility and multihoming support for mountain rescue
Introducing an IP-based communication system into the mountain rescue domain would enable carrying out search and rescue missions in an effective way. With efficient mobility and multihoming support, a Mountain Rescue Team would be able to establish more effective and reliable Internet communication. In this paper, we present the Multihomed Mobile Network Architecture (MMNA), a comprehensive multihomed mobility solution for complex nested mobility scenarios. It provides a multihoming management mechanism for gateway discovery and selection, on top of an efficient multihomed mobility model integrating different mobility and multihoming protocols. The design of the MMNA solution is first presented. We then describe how the MMNA was experimentally implemented and evaluated in a testbed setup to examine its effectiveness and feasibility considering a use case example of a mountain rescue scenario. The results highlight the practicality and advantages of deploying the MMNA into such a critical real-world scenario
MROM scheme to improve handoff performance in mobile networks
Mobile Router (MR) mobility supported by Network Mobility
Basic Support Protocol (NEMO BS) is a Mobile IPv6 (MIPv6) extension that
supports Host Mobility. Proposed Multihoming and Route Optimization for
MANEMO (MROM) scheme is designed to provide Route Optimization (RO)
and Multihomed in NEMO architectures. This paper proposes two novel
schemes; MANEMO routing scheme and Multihoming-based scheme. These
are to provide support for next generation networks. The proposed MROM
scheme differs from other schemes for NEMO environment because it considers
the requirements of more application flows parameters as packet lost delivery,
handoff delay as well as throughput). Another difference is that not only the
network infrastructure can begin the functionality of flow routing, but also an
Edge Mobile Router (EMR) can do this flow for routing. Moreover, it utilizes
the state of the art and presently active access network to perform the separation
of each flow in mobile network. Thus, proposed MROM exhibits multihoming
features and improves handoff performance by initiating flow-based fast
registration process in NEMO environment. A handoff method is proposed with
enhanced functionalities of the Local Mobility Anchors (LMA), Mobile Routers
(MRs) and signaling messages with a view to achieve continuous connectivity
through handoff in NEMO. Both analytical and simulation approaches are used.
Analytical evaluation is carried out to analyze packet delivery lost and handoff
delay of our proposed scheme. It was also shown that cost of signaling
messages and packet delivery are contributing to total handoff cost. At the
simulation part, network simulator 3 (NS 3) has been used as the tool to get
performance metrics that have been considered like packet delivery ratio,
handoff delay, and packet loss. Our proposed scheme (MROM) has been
benchmarking to the standard NEMO BS Protocol and P-NEMO. In this paper,
we discuss proposed MROM for next generation networks, providing detailed
analysis with a numerical model, proposed MROM, by maximizing the handoff
performance, has been justified to have better mobility support than the
ordinary NEMO BS Protocol and PNEMO.

Design and Experimental Evaluation of a Route Optimisation Solution for NEMO
An important requirement for Internet protocol (IP)
networks to achieve the aim of ubiquitous connectivity is network
mobility (NEMO). With NEMO support we can provide Internet
access from mobile platforms, such as public transportation vehicles,
to normal nodes that do not need to implement any special
mobility protocol. The NEMO basic support protocol has been
proposed in the IETF as a first solution to this problem, but this
solution has severe performance limitations. This paper presents
MIRON: Mobile IPv6 route optimization for NEMO, an approach
to the problem of NEMO support that overcomes the limitations
of the basic solution by combining two different modes of operation:
a Proxy-MR and an address delegation with built-in routing
mechanisms. This paper describes the design and rationale of the
solution, with an experimental validation and performance evaluation
based on an implementation.Publicad
