Hierarchical mobile network binding scheme for route optimization in NEMO

Abstract

Recently, there has been a great deal of research on network mobility management that can support the movement of a mobile network consisting of several mobile nodes. The IETF NEMO working group proposed a basic support protocol, which defines methodology for supporting network mobility by using bi-directional tunneling between the home agent and the mobile router. This protocol, however, suffers from the 'pinball routing problem,' and most of the research attempts to solve this problem still have limitations in the efficiency of intra-domain communication. Moreover, these methods require additional binding procedures in case of the root mobile router handover. In this paper, we propose new route optimization methodology that can remedy these limitations by using asymmetric tunneling and a hierarchical local binding mechanism, which can provide faster signaling and data transmission. It can also be easily extended to support micro-mobility without the need for additional extensions. The performance is evaluated by simulation which can

“…In [19], number of RO schemes have been introduced to overcome aforementioned disadvantages. [21]. Packets sent by CN to MNN, using MNN's HoA, reaches MNN's HA that tunnel packets to TLMR's CoA or HoA.…”

Route optimization using the distributed binding update for nested mobile networks

“…However, RRH increases the size of the packet header and suffers from a BU storm when the root-MR handover occurs. In order to solve the pinball routing problem and concentrated load issues at the root-MR, a route optimization methodology called hierarchical mobile network binding (HMNB) [11] was proposed by Jeong et al on the basis of an asymmetric tunneling technique and a destination routing header to provide the intra-domain data communication and efficient route optimization. However, HMNB introduces much signaling overheads during the inter-domain handover and a long handover delay for some cases of the root-MR handover.…”

Pros and cons of route optimization schemes for network mobility and their implications on handovers

“…Another approach called ‘hierarchical mobile network binding’ (HMNB) for RO has been presented in Ref. [30], which uses asymmetric tunneling and a hierarchical local binding mechanism. Data from an MNN in a visiting mobile network can be sent directly to the CN with normal routing without tunneling.…”
