Modeling and Evaluation of Network-based Partial Distributed Mobility Management

Gil-Dong Hong*, Chun-Hyang Seong**†

Abstract

DMM(Distributed Mobility Management) mechanisms have been actively studied in and around the IETF to solve several limitations of centralized mobility management schemes. In DMM, data traffic is distributed in an efficient way and does not rely on a central anchor node to manage IP mobility sessions. In this paper, the network-based partial distributed mobility management scheme is suggested and the simulation models and programs are developed and verified by simulations under various traffic environments. The simulation results show that the developed models for DMM are useful for mobility management studies in wireless network environment.. <영문 요약문은 10줄 내외로 작성>[신명조8.5]

1. Introduction

Modeling and Evaluation of Network-based Partial Distributed Mobility Management

Most existing solutions for IP mobility are based on the concept that the specific anchor node maintains the up-to-date binding information between HoA(Home Address) and CoA(Care-of-Address) of the MNs(Mobile Nodes). In these schemes, data traffic is delivered through tunneling between the anchor node and MNs or between the anchor node and ARs(Access Routers). Therefore, the anchor node should not only manage the binding information of all MNs in a centralized fashion but also perform encapsulation and de-capsulation of all data traffic transmitted and received by all MNs. As an example, in MIPv6(Mobile IPv6) and PMIPv6 (Proxy MIPv6) protocols, all signaling messages and data traffic converge on a HA(Home Agent) or a LMA(Local Mobility Anchor) node functioned as an anchor node[1]. Centralized mobility solutions are prone to several problems and limitations such as a bottleneck and SPOF(Single Point Of Failure)[2], network scalability, and sub-optimal routing paths.

In recent years, a new trend in mobile network evolution for solving the centralized mobility drawbacks is to flatten mobility architecture by confining mobility support in the access network, named DMM(Distributed Mobility Management), which would keep the rest of the network unaware of the mobility events and their support. Distributed mobility solutions have attracted great interest of researchers and are being actively standardized by the IETF dmm(Distributed Mobility Management) and netext (Network-Based Mobility Extensions) working groups[3].

2.1 Structure Analysis

MIPv6 is a host-based IPv6 mobility solution, which requires client functionality in the IPv6 stack of a MN. Unlike MIPv6, where the MN signals its location changes to the HA(Home Agent), PMIPv6, which is a network-based mobility solution, introduces a MAG(Mobile Access Gateway) node and a LMA(Local Mobility Anchor) node. The MAG acts as a proxy for the MN and the LMA does the same function as the HA. Both MIPv6 and PMIPv6 are based on centralized mobility approach in which a central mobility anchor, HA or LMA, manages all data packets as well as signaling messages to be sent or received by the MN and the CN. Fig. 1 illustrates data paths and tunneling sections in centralized mobility management approaches, MIPv6, PMIPv6 and 3G/LTE. Table 1 shows the results of evaluation. <모든 그림과 표는 본문에서 반드시 인용되어야 함>

5. Conclusion and future works

In this paper, for the extensive and comprehensive study about distributed mobility management, the network-based partial DMM scheme is suggested and simulation models and programs have been developed on the basis of PMIPv6 protocol and verified by simulations under various traffic environments.

The simulation results for performance comparison of DMM, PMIPv6 and MIPv6 protocols include traffic sent/received, End-to-end Packet transfer delay, binding delay, CPU utilization, WLAN load in a MN, etc. and show that the developed models for DMM are useful for mobility management studies in wireless network environment.
