To ensure efficient session continuity for every node in a Mobile Network NEMO Basic Support (NBS) protocol, an extension of MIPv6 has been proposed. The protocol NBS is not directly applicable in PMIPv6 domain as it is a network based mobility management protocol and mobility is transparent from mobile node. It is already proved that to support NEMO BSP in PMIPv6 domain some modifications are required...
Designing an efficient micro-mobility scheme for network mobility (NEMO) is an important issue. The Micro-NEMO is a well known protocol for micro mobility in NEMO. It has significantly lower signaling overhead and handoff latency. But, it suffers from single point failure problem. In this paper, we propose micro-NEMO++, an extension of micro-NEMO protocol, to eliminate the single point failure problem...
NEtwork MObility (NEMO) provides that a moving network involving mobile network nodes (MNNs) can move around the Internet without loss of connection. NEMO Basic Support (NBS) has been developed as an extension of Mobile IPv6 (MIPv6) so that it succeeds to drawbacks of host-based mobility management protocol. In NBS, the moving network keeps its connectivity with its home agent (HA) through its registration...
To support IP-mobility of networks in motion, IETF proposed Network Mobility (NEMO) protocol that uses various signaling messages to ensure connectivity of the mobile nodes with the Internet. However, there has been no comprehensive cost analysis of mobility protocol entities that considers all possible costs. In this paper, we have developed analytical models to estimate total costs of key mobility...
In this paper, we analyze a one-way hash chain based authentication scheme proposed by Haddad and Krishnan. The authentication scheme has been introduced for improving handover performance in Fast Mobile IPv6 (FMIPv6), but as we argue in this paper the authentication scheme is vulnerable to redirect and DoS attacks. We present strengths and weaknesses of the authentication scheme. In addition, a possible...
The Network Mobility (NEMO) protocol allows a mobile network (MONET) to move around and maintains the session connectivity of nodes in the MONET. In the nested NENO architecture, MRs connects in hierarchy. The MN will detect more than one access routers and have to determine the best one to handoff. In this paper, we proposed an efficient fast handoff scheme in hierarchical mobile IPv6 for NEMO. We...
Sharing communications are not easy to do in the mobility networks (MONETs) for the limited bandwidth and the overhead of tunneling. Multicast is an intuitive method to solve this problem. To improve the performance, the multicast topology should be redesigned for the MONETs. We proposed an efficient communication algorithm with multicast schemes in a network mobility (NEMO) environment. The Mobile...
To support network mobility in wireless network, NEMO BSP is proposed by IETF. Mobility support paradigm is going to move from the MN to Network. PMIPv6 is the latest protocol based on local mobility management and network-based mobility. The mobile node can freely move between PMIPv6 network and mobile network. The previous NEMO protocols based on PMIPv6 cannot support this kind of mobility due to...
In nested mobile network, traffic should be encapsulated and tunneled for each level of nesting, which leads to increased overhead and sub-optimal routing. In this paper, we investigate a localized mobility management framework and propose a source routing binding update mechanism based on mobile anchor point (MAP) to optimize the route of nested mobile network that supports NEMO basic support protocol...
In the traditional network management architecture, there is an implicit assumption that a managed device will not change its location. Location related information where available is static, and it is used for simple reporting purposes. However with mobile devices these attributes are inherently dynamic. Monitoring processes of management information also encounter difficulties of network instability...
Network mobility (NEMO) basic support protocol (NBS) enables mobile networks to work well under Internet, but leads to pinball routing problem. A MAP based route optimization scheme (MROS) is proposed to provide route optimization and reduce mobility management overhead for mobile networks. MROS uses MAP which is a mobility management technique in HMIPv6 to construct a hierarchical mobile network,...
In recent years, mobile network has evolved greatly with the existences of MANET, wireless sensor network, mobile IP, NEMO and etc. The advent of network mobility (NEMO) tends to provide seamless Internet connectivity to all the nodes within a mobile network regardless of their current points of attachment with the usage of a mobile router. Multicasting support is one of the key technologies in next...
NEMO basic support (NBS) protocol ensures session continuity for all the nodes in a mobile network, however, there exists a serious pinball routing problem. To overcome this one, there are many route optimization (RO) solutions such as bi-directional tunneling (BT) mechanism, aggregation and surrogate (A&S) mechanism, recursive Approach, etc. The A&S RO mechanism is known to outperform the...
Multicast is an efficient method to transmit datagrams in the Internet. In this paper, we provide a multicast algorithm in a network mobility (NEMO) environment. We propose the mobile router forwarding scheme (MRFS) algorithm. There are two advantages in the MRFS algorithm. First, MRFS reduces the storages in every MR especially in the TLMR (top level MR). Second, MRFS transmits multicast datagrams...
