Performance analysis of mobile IP and SLM

We present a performance analysis of two architectures for Internet host mobility management, namely, mobile IP and session layer mobility management (SLM). The mobile IP architecture is designed with the principle that the fixed Internet hosts should remain unmodified while only the underlying IP routing infrastructure should change. By contrast, SLM requires no changes to the existing IP infrastructure as well as the transport protocols but only modifications to the session layer protocols and the applications at the end hosts. We compare the performance advantages of the end-to-end mobility scheme with the network-layer mobility, scheme, and prove by experiments that the end-to-end scheme, i.e. SLM, is a better solution for host mobility in many situations.
