In this paper, we propose a mobile TCP socket which is the second step
of our two step approach to support mobility. The first step of our
approach is to support portability as reported earlier. In our mobile
TCP socket, a mobile mapping is introduced, which maps TCP associations
to underlying TCP connections. The mobile mapping can be implemented
in the socket layer and on top of TCP/IP protocol layers. Our approach
achieves high compatibility with current TCP/IP protocols, due to the fact
that neither of the two steps in our approach impose any changes on TCP/IP
protocols nor the underlying Link layer. At the same time, our approach
can reduce both the propagation cost for distributing location information
of mobile hosts and the forwarding cost for forwarding IP datagrams across
the Internet. The concept of mobile mapping and its implementaion
details are given in this paper.
