A Multicast Extension for Enhanced Mobile IP by Home Agent Handover
نویسندگان
چکیده
In order to improve the routing efficiency and reduce handoff latency, we have proposed an enhancement of Mobile IP (MIP) called MIP with Home Agent Handover (HH-MIP) to enjoy most of the advantages of Route Optimization MIP (ROMIP) but with only a small increase of signaling overhead. In HH-MIP, the concept of Temporary Home Agent (THA) was proposed and the mobile host (MH) registers the new CoA with its THA rather than its original HA. In this paper, we propose a multicast extension for HHMIP (HH-MIP/ME). HH-MIP/ME reduces routing inefficiency in bi-directional tunneling without generating large signaling overhead. Simulation results demonstrate that the proposed scheme enjoys small handoff latency as well as routing efficiency and the number of control packets generated in proposed scheme is significantly less than that in other approaches.

Mobile Internet Protocol version 6 (MIPv6) has been proposed to solve the problem of mobility in the new era of Internet by handling routing of IPv6 packets to mobile nodes that have moved away from their home network. Users will move frequently between networks, as they stay connected to the Internet. Thus, as mobility increases across networks, handovers will significantly impact the quality ...

Multicast and mobility are two important research topics in the Internet nowadays. Although much research has been done in these two areas, mobility support for IP multicast still remains a problem. Most Internet protocols work well only when the hosts are static. Research on mobility support has so far been focused on the unicast case. Mobility support for IP unicast (Mobile IP) mainly aims at...

Mobile IP is designed to support uninterrupted connectivity of mobile computers as they roam from place to place. We propose a fast intra-domain and inter-domain handoff scheme using the location of routers to meet the delay and packet loss requirements of real-time services. The scheme achieves an intelligent and dynamic neighborhood discovery and avoids the use of multicast addresses in intra...
