Abstract
Locating an object so as to deliver
messages intended for the object is a basic task
of every distributed system. Most systems that
support mobile objects use home-based
tracking strategies wherein every object has a
designated home and all messages for an object
(or at least the first one in the same session) are
routed through its home. One problem of this
type of protocols is that an object becomes
inaccessible when its home fails or
communications to its home are blocked.
We investigate distributed directory
structures and algorithms for tracking mobile
objects that exhibit a high degree of tolerance
to node and communication failures. This
research is a continuation of a previous
NSC-sponsored project titled ``Distributed
Mutual Exclusion and Object Tracking' (NSC
89-2213-E-002-021) where we explored the
idea of adapting token-based mutual exclusion
algorithms for object tracking. We derive from
existing token-based algorithms two schemes
for tracking mobile objects. Our main
contribution lies in addressing fault tolerance
issues.
