This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract Mobile IPv4 (RFC 3344) uses the home agent (HA) to a...

Combining the advantages of FMIPv6 and HMIPv6 (FHMIPv6) is more suitable for time –sensitive services. We propose an improvement based on it by optimizing the address configuration stage on MN (Mobile Node) and setting handover initation stage on MAP (Mobility Anchor Point) so that the handover delay and packet loss is reduced. Our paper presents simulation result of these solutions (Hierarchic...

The paper presents a simulation-based study of topological characteristics of a mobile wireless ad-hoc network, namely, connectivity, coverage and diameter. Knowing these characteristics of the network aids in design of new distributed protocols as well as in predicting the performance and robustness of distributed protocols running on the network. The nodes exhibit intelligent mobility pattern...

Abstract – Mobility support for mobile networks will be more important as the mobile Internet becomes increasingly popular. To support mobile networks, the concept of prefix scope binding (PSB) is being discussed in IETF; however, by only applying this concept to Mobile IPv6 (MIP), the problem of packet loss still remains. In this paper, we apply the PSB concept to our proposed protocol, the Hi...

This work presents a simple mobility scheme for IP-based networks, termed the “anchor chain” scheme. The scheme combines pointer forwarding and caching methods. Every mobile host (MH) is associated with a chain of anchors that connects it to its home agent. Each anchor defines the location of the MH at a certain degree of accuracy. The accuracy is increased along the chain until the attachment ...

The development of wireless network technology and user demands for mobility support have motivated the IETF to introduce mobile IP, mobile IPv6, and its extension, the network mobility (NEMO) basic support protocol. In the NEMO environment, mobile networks form a nested structure. Nested mobile networks based on NEMO basic support (NBS) protocol have the pinball routing problem because packets...
