Abstract

Network Mobility Basic Support Protocol (NEMO BSP) is considered as the most widespread network mobility protocol at the present time which is a logical extension of the MIPv6 operation. Hence, Location Update (LU) procedure of NEMO BSP is almost similar to MIPv6 registration apart from setting of the MR flag and sending of prefix in the Binding Update (BU). However, in NEMO network, providing an uninterrupted Internet connectivity during handoff (seamless handoff) is still an open issue for the current researchers in terms of handoff delay, packet loss, service disruption time and signaling overhead respectively. To concentrate on these issues, in this study, an Intra Domain Mobility scheme in NEMO (IDM-NEMO) is proposed that aims to reduce signaling overhead by incorporating an improved version of Fast HMIPv6 scheme with NEMO network to attain continuous Internet connectivity at the time of movement from one subnet to another. Additionally, in order to analyze the location update cost, a mathematical model has been developed and compared with the standard NEMO BSP. The analytical result demonstrates that the proposed scheme reduced location update cost by 52% than that of NEMOBSP.

Highlights

Nowadays, the key concern for the industries is the support of network mobility for the whole network; this is due to the existing Internet connection for the period of handoff
In Network Mobility (NEMO), MR executes the whole task on behalf of Mobile Network Nodes (MNNs) during handoff, which creates a bi-directional tunnel between the serving Mobile Router (MR) with its Home Agent (HA) and carries out the handoff after implementing the layer 2 switching, defining the basic inspiration of NEMO BSP (Devarapalli et al, 2005)
The conception of this study is to explore the present handoff solution in NEMO network

Summary

INTRODUCTION

The key concern for the industries is the support of network mobility for the whole network; this is due to the existing Internet connection for the period of handoff. Authors (Johnson et al, 2004) in recent time Internet Engineering Task Force (IETF) has come up with a solution (e.g. MIPv6) to resolve the shortcomings of existing IP addressing to sustain the host mobility. In NEMO, MR executes the whole task on behalf of MNNs during handoff, which creates a bi-directional tunnel between the serving Mobile Router (MR) with its Home Agent (HA) and carries out the handoff after implementing the layer 2 switching, defining the basic inspiration of NEMO BSP (Devarapalli et al, 2005). Network Mobility Basic Support Protocol (NEMO BSP) has been developed to give an uninterrupted access to the Internet when there comes a change in MR or MN, based on it’s point attachment. Route optimization needs to be focused and multihoming technique as NEMO BSP is not considered as these mechanisms due to security reasons (Johnson et al, 2004; Shayla et al, 2012)
