An Efficient Scheme for Supporting Network Mobility in Partially Distributed Mobility Management

Abstract

In this paper, we apply the Network Mobility protocol (NEMO), which is capable of managing group - based network mobility, in a partially Distributed Mobility Management (DMM) environment. This paper proposed an efficient scheme to support network mobility. When the PR initially accesses the AR, it requests the AR for two prefixes. The first prefix is the Home Network Prefix (HNP), required for the configuration of PR’s IP address and the other is Mobile Network Prefix (MNP) which is required for IP configuration of MN. Therefore, even if the MN is added, it is expected that the packet transmission cost is better as compare to the existing schemes, as there is no need for prefix request and information update related signaling between PR and Centralized Mobility Database (CMD). Through analytical results we have shown that our proposed scheme outperforms the existing schemes in terms of packet delivery cost.
