Implementation and performance evaluation of application layer MIP-LR

In order to avoid triangular routing und kernel dependency associated with the basic mobile IP, an application layer solution based on mobile-IP with location registers (MIP-LR) has been designed and prototyped in a laboratory environment. Application layer MIP-LR augments the basic MIP-LR scheme with some application layer techniques that enable capturing and mangling of packets and thus provides kernel independence from deployment perspective. Results from analysts and laboratory prototype demonstrate that one can attain up to 50 percent reduction in management overhead and 40 percent improvement on latency compared to standard mobile IP in co-located mode. In addition to bandwidth efficiency gain it also provides survivability features in an ad hoc environment.
