Network layer mobility: an architecture and survey |
| Pravin Bhagwat, Charles Perkins, Satish Tripathi |
| In this article we explore various network layer concepts that play
a crucial role in the design of mobile networking systems. We show that
mobility is essentially an address translation problem and is best resolved
at the network layer. We describe services that must be supported at the
network layer to carry out the task of address translation. Using these
service primitives as building blocks, we describe a network-layer architecture
which enables smooth integration of mobile end systems within the existing
Internet. A summary of some of they key Mobile IP proposals is presented,
and it is shown that each proposal can be viewed as a special case of the
architecture outlined in this article.
