Performance analysis of BUNSD-LMA

The IETF is developed Network Mobility Basic Support (NEMO BSP) to support session continuity and reachability to the Mobile Network Nodes (MNNs) as one unit while they move. While NEMO move and attached to different networks, it needs to register the MNNs. This function of registration decreases the performance of NEMO. NEMO BSP suffers from some challenges. The most important of these challenges are route optimization, seamless mobility, handover latency and registration time. Binding Update No Sense Drop (BUNSD) Binding Cache Entry (BCE) in Local Mobility Anchor (LMA) is proposed to find a possible solution to MNNs. MNNs that are roaming in a Proxy Mobile IPv6 (PMIPv6) domain to perform seamless mobility while they are maintaining their session continuity through mobile router (MR). In this paper, BUNSD-LMA is analyzed mathematically with NEMO BS based on handover latency, total packet delivery delay cost, and throughput time during handoff. The analytical result shows that the BUNSD-LMA had better performance in term of handover, and registrations of MNNs. As a result the total packet loss is decreased and seamless mobility of MNNs enhanced compared to NEMO BS benchmarks. Keywords: NEMO, PMIPv6, BUNSD, MR, MAG, LM

Development of an enhanced scheme for NEMO environment

The frequent change of Mobile Node (MN) location is going to increase rapidly as everything is a mobile presently. In order to achieve seamless mobility, mobility managements are considered as very important. The mobile IPv6 MIPv6 is proposed and standardized by IETF. It is introduced to improve the host mobility management. However, it faces different problems when mobile nodes move between different network infrastructures. To overcome these issues, proxy mobile IPv6 PMIPv6 is introduced. PMIPv6 is a network based mobility management intended to improve handover delay by functioning mobility managements on behalf of mobile node. However, PMIPv6 added additional cost to the network by implementing mobile access gateway and bi-directional tunnel. In addition, network mobility, NEMO standardized as extension to MIPV6 to support session continuity to the internet services on behalf of mobile network nodes. Nevertheless, they still issues of packet loss and handover delay during the registration of MNNs and handoff of NEMO. The research within this area is very active, trying to solve these problems by integration of different mobility management’s schemes. In this paper, we have focused on evaluating different integrations of mobility managements with NEMO. Then we proposed a BUNSD-LMA schema, to solve the problem of packet loss and handover delay, by integration of PMIPv6 with NEMO BS, using pre-registration of MNP (HNP) in advance with short time in binding update extensions message option format

Evaluation study of mobility management protocol in NEMO

The Internet Engineering Task Force has developed Network Mobility Basic Support Protocol. One of the important issues of network mobility management schemes is the hands-off management. This paper presents the network mobility management schemes into two classifications in order to highlight the limitation and improvement of such schema and comparing different handover techniques that have been proposed to enhance the performance during handover. Finally, some common solutions have been used to solve seamless mobility related problems were briefly investigated and evaluated. However, the researchers challenge sit side of integration of these schemes. The current trend of network mobility at IP level at a huge scale relies on the ability to offer advanced mobility management that can coexist with the presently deployed protocols

A novel scheme of binding update no sense drop BCE in LMA

In this paper, we investigate different integrations of mobility management’s schemes. This paper proposed a Binding Update No Sense Drop BCE in LMA BUNSD-LMA schema. The BUNSD-LMA aims to find possible solution to allow MNNs that are roaming in a PMIPv6 domain to perform seamless mobility whiles maintaining their session continuity through mobile router. In this scheme, we integrate PMIPv6 with NEMO BS and extend an existing binding update message format to register the prefix of MNNs in advance with short time. In addition to this, we considering the concept of investigated proposed schemas to enhance our solution
