A new mobility management scheme for mobile IP-based wireless networks

This paper introduces two new approaches, co-operated with the mobile routing table (MRT), for optimizing the routing path such that the triangular routing problem is avoided. The first approach combines an ICMP network-mask query and directed broadcast mechanism to find the routers. The other approach uses a tracking mechanism, similar to traceroute, to find all the MRT routers on the path from home agent to corresponding node. We analyze and compare both the standard mobile IP (MIP) and the proposed scheme. It is clear that the proposed scheme acts like the MIP in the worst case, and like the MIP-route optimization in the best case.
