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...
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...
