Seamless Mobility Management Schemes for IPv6-based Wireless Networks

Abstract

Mobility management is one major challenge for wireless network design. Advanced wireless technologies provide mobile nodes with multi-mode radio interfaces, so subscribers can benefit from disparate mobile communication systems. Meanwhile, researchers are putting efforts into standardization of IPv6-based mobility protocols. Hence, wireless networks can offer more flexible mobility support than ever before. However, as the demands for high-speed Internet access and multimedia services increase, guaranteeing host mobility with quality of service provisioning becomes more difficult. Both network connectivity and session continuity need to be carefully handled during handover. This paper proposes a new mobility protocol, called seamless mobile IPv6 (SMIPv6). Its novelty consists of pre-configuring bidirectional secure tunnels among access routers before handoff, as well as using such tunnels to guarantee handoff seamlessness. To evaluate the performance, simulations are conducted using OPNET Modeler v.12.0, of which results demonstrate that SMIPv6 delivers better performance than MIPv6 in terms of handoff latency and packet losses.

A Comprehensive Review of Enhancements and Prospects of Fast Handovers for Mobile IPv6 Protocol

“…even before the MN initiates the handover. An in-advanced tunnel establishment scheme in [65], proposes a tunneling protocol module which resides in each AR and establishes tunnels with neighboring ARs beforehand. It also takes care of the signaling required to establish tunnels, as well as deciding and negotiating the desired tunnel characteristics, which include security and encryption methods between the two tunnel endpoints.…”

Dynamic anchor points selection for mobility management in Software Defined Networks

“…Various mobility management mechanisms are implemented in different protocol layers to target different functionalities (Zhang et al, 2014). In the physical layer, mobility management carries out the procedures of detach and attach to different access points during handover.…”

Novel Seamless Mobility Protocol for Next Generation Wireless Networks

“…Such a period is defined as handover latency [12]. MIPv6 mobility management process provides long handover delays, significant packet losses, and high mobility signaling overheads, thus unacceptable and detrimental for real-time applications, causing user-perceptible service deterioration during handover [11] [13] To improve the performance of MIPv6, many mobility protocols have been proposed by IETF and researchers at industry and university, such as FMIPv6 [5], HMIPv6 [4], FHMIPv6 [6] [7], simultaneous bindings for FMIPv6 or sbFMIPv6 [14], a novel FMIPv6 and HMIPv6 integration mechanism [15], enhanced fast handover with low latency for mobile IPv6 [16], simplified fast handover in mobile IPv6 networks [17], an efficient scheme for fast handover over HMIPv6 [18], seamless MIPv6 (SMIPv6) [19], to name a few. These solutions can be sorted into two categories: network architecture design and fast handover scheme.…”
