Distributing Multiple Home Agents in MIPv6 Networks

Mobile IPv6 is a protocol that guarantees mobility of mobile node within the IPv6 environment. However current Mobile IPv6 supports simple the mobility of the mobile nodes. If a mobile node is moved away from the home link, it takes time for mobile node to make a registration and binding update at the home agent. In this paper, we propose Distributing Multiple Home Agents (DMHA) scheme. Using this scheme, a mobile node performs binding update with the nearest home agent, so that the delay of binding update process can be reduced. It also reduces the fault rate of handoff up to about 38.5% based on the same network parameters. Experimental results presented in this paper shows that our proposal has superior performance comparing to standard scheme.
