Routing scheme for macro mobility handover in hierarchical mobile IPv6 network

Significant problems in basic mobile IPv6 occur due to its inability to support micro-mobility because of long delay and high packet loss during handover. Hierarchical mobile IPv6 (HMIPv6) as an extension of basic Mobile IPv6 solves the problem by separating the handover management to macromobility and micro-mobility. HMIPv6 introduced a new protocol element called Mobility Anchor Point (MAP) to manage the mobility. HMIPv6 can reduce the delay and the amount of signaling during handover. However the protocol still cannot meet the requirement for traffic that is delay sensitive such as voice especially in macro mobility management. Duplicate address detection and the transmission time for the handover operation could cause high handover delay

A handover management scheme for mobile IPv6 networks

Mobile IPv6 provides IP layer mobility management for IPv6 networks. Despite many advantages it offers in comparison to Mobile IPv4, handover management still remains an issue for Mobile IPv6. For real-time connections, the handover latency and signaling overhead incurred by the protocol may become significant. This paper presents a new method named crossover MAP based hierarchical mobile IPv6 (XMAP-HMIPv6), which inherits the advantage of hierarchical mobile IPv6 of reducing signaling load for inter-domain mobility and incorporates an analytical model for the performance analysis of this new scheme along with other existing handover management proposals. Finally, we present analytical results in different environments and compare our scheme with other existing proposals. The analytical model results show that, our scheme performs almost similar to [F+H] MIPv6 in terms of reducing handover latency and outperforms both HMIPv6 and MIPv6

ANALISIS PERFORMANSI MOBILE IPv6 DAN HIERARCHICAL MOBILE IPv6 PADA WIRELESS LOCAL AREA NETWORK

Mobile IPv6 (MIPv6) merupakan sebuah protokol mobility management yang memungkinkan mobile node untuk selalu dapat terkoneksi walaupun melakukan perpindahan pada cakupan jaringan IPv6. Kebutuhan akan MIPv6 menjadi penting karena sebuah perangkat mobile tidak dapat menjaga konektivitasnya dengan link sebelumnya ketika melakukan perpindahan lokasi dan pergantian alamat IP. Tujuan dari protokol mobility management adalah agar aplikasi pada jaringan dapat beroperasi secara kontinu di jaringan nirkabel ataupun kabel ketika mobile node melakukan perpindahan dalam jaringan. Pada tugas akhir ini dilakukan analisa perbandingan performansi MIPv6 dengan rangkaian pengembangannya yaitu Hierarchical Mobile IPv6 (HMIPv6) untuk melihat seberapa besar peningkatan performansi yang dapat dilakukan. Pengujian kinerja protokol ini dilakukan pada cakupan Wireless Local Area Network (WLAN), dimana mobile node melakukan perpindahan dari satu jaringan WLAN ke jaringan WLAN lain yang disimulasikan dengan Network Simulator 2. Parameter performansi yang diukur pada sisi sistem adalah packet loss dan handoff latency sementara pada sisi mobile node adalah throughput yang diuji dengan peningkatan kecepatan pergerakan dan penambahan jumlah mobile node. Hasil penelitian menunjukkan bahwa HMIPv6 tidak memperbaiki performansi pada keseluruhan parameter uji. Pada skenario pertama, performansi HMIPv6 terhadap MIPv6 telah menurunkan packet loss sebesar 16.18%, menaikkan handoff latency sebesar 0.13% dan menurunkan throughput sebesar 3.01%. Pada skenario kedua, performansi HMIPv6 terhadap MIPv6 telah meningkatkan packet loss sebesar 8.25%, menurunkan handoff latency sebesar 25.36% dan menurunkan throughput sebesar 1.49%.

Roaming Real-Time Applications - Mobility Services in IPv6 Networks

Emerging mobility standards within the next generation Internet Protocol, IPv6, promise to continuously operate devices roaming between IP networks. Associated with the paradigm of ubiquitous computing and communication, network technology is on the spot to deliver voice and videoconferencing as a standard internet solution. However, current roaming procedures are too slow, to remain seamless for real-time applications. Multicast mobility still waits for a convincing design. This paper investigates the temporal behaviour of mobile IPv6 with dedicated focus on topological impacts. Extending the hierarchical mobile IPv6 approach we suggest protocol improvements for a continuous handover, which may serve bidirectional multicast communication, as well. Along this line a multicast mobility concept is introduced as a service for clients and sources, as they are of dedicated importance in multipoint conferencing applications. The mechanisms introduced do not rely on assumptions of any specific multicast routing protocol in use.Comment: 15 pages, 5 figure

Performance Analysis of Multicast Mobility in a Hierarchical Mobile IP Proxy Environment

Mobility support in IPv6 networks is ready for release as an RFC, stimulating major discussions on improvements to meet real-time communication requirements. Sprawling hot spots of IP-only wireless networks at the same time await voice and videoconferencing as standard mobile Internet services, thereby adding the request for multicast support to real-time mobility. This paper briefly introduces current approaches for seamless multicast extensions to Mobile IPv6. Key issues of multicast mobility are discussed. Both analytically and in simulations comparisons are drawn between handover performance characteristics, dedicating special focus on the M-HMIPv6 approach.Comment: 11 pages, 7 figure

Macro/micro-mobility fast handover in hierarchical mobile IPv6

Mobile Internet Protocol version 6 (MIPv6) has been proposed to solve the problem of mobility in the new era of Internet by handling routing of IPv6 packets to mobile nodes that have moved away from their home network. Users will move frequently between networks, as they stay connected to the Internet. Thus, as mobility increases across networks, handovers will significantly impact the quality of the connection and user application. However, MIPv6 only defines means of managing global (macro)-mobility but does not address micro-mobility separately. Instead, it uses the same mechanism in both cases. This involves long handover delay and signaling load. The Hierarchical Mobile IPv6 (HMIPv6) protocol has been proposed as an extension of basic MIPv6 to solve this problem by splitting the handover management into macro-mobility and micro-mobility schemes. HMIPv6 introduced a new protocol agent called Mobility Anchor Point (MAP) to manage mobility and serve as a local entity to aid in mobile handover. The handover (or registration) operation is the operation when MN registers its presence to its Home Agent (HA) and Correspondent Node (CN). This paper proposes a mechanism to perform fast handover in HMIPv6 by adopting the multicast technique to the MAP for both macro-mobility and micro-mobility management. Our proposal is designed to minimize service disruption that occurs during the registration operation. We simulate the performance using network simulator (NS-2) and we present and analyze the performance testing for our proposal by comparing it with the basic hierarchical mobile IPv6. The results show that our scheme allows the MN to receive packets faster than the basic HMIPv6

ANALISIS PERFORMANSI MOBILE IPv6 SUITE PADA WIRELESS LOCAL AREA NETWORK DENGAN MENGGUNAKAN NETWORK SIMULATOR 2

Mobile IPv6 (MIPv6) is a mobility management protocol that enables mobile nodes to always be connected while moving around in IPv6 network. The need for MIPv6 is important because a mobile device cannot maintain its connectivity with the previous link when changing location and IP address. The purpose of the mobility management protocol is that the applications on the network can be countinue on the network. Mobile IPv6 itself requires optimization to improve performance so in this study conducted a comparison analysis performance of MIPv6 with its development series that is Hierarchical Mobile IPv6 (HMIPv6) to see the impact of performance improvement that can be done. Implementation of this protocol performance is done on the scope of Wireless Local Area Network (WLAN), where mobile node to moving from one WLAN network to another WLAN network and simulated with network simulator 2. Performance parameters that measured are average throughput, packet loss and handoff latency which scenarios increasing the speed of node movement. From the simulation results, it can be seen that HMIPv6 performs better than MIPv6 protocol, because in HMIPv6 provides lower packet loss and handoff latency rather than MIPv6.Mobile IPv6 (MIPv6) merupakan sebuah protokol mobility management yang memungkinkan mobile node untuk selalu dapat terkoneksi walaupun melakukan perpindahan pada cakupan jaringan IPv6.
