A mobile TCP socket.
[POSTSCRIPT (191716 bytes)]
Abstract: 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
implementation details are given in this paper.
