This article presents the Terminal Independent Mobility for IP (TIMIP), whi
ch is a new architecture for IP mobility in wireless access networks. TIMIP
is based on principles similar to those in the CIP and HAWAII architecture
s proposed at IETF and equally suited for micromobility scenarios. With TIM
IP, terminals with legacy IP stacks have the same degree of mobility as ter
minals with mobility-aware IP stacks. Nevertheless, it still uses MIP for m
acromobility scenarios. In order to support seamless handoff, TIMIP uses co
ntext-transfer mechanisms compatible with those currently in discussion at
the IETF SeaMoby group.
