Abstract
This paper addresses the problem of fine-grained
data replication in large distributed systems, such as
the Internet, so as to minimize the user access delays.
With fine-grained data replication, certain data
objects, as opposed to a complete site, are duplicated
at multiple servers. In this paper, we abstract the
distributed system as an agent-based model wherein
mobile agents on behalf of their nodes continuously
compete for allocation and reallocation of data
objects. However, since these agents do not have a
global view of the system, the optimization process
becomes highly local. This localization may encourage
these selfish agents to alter the output of the resource
allocation mechanism in their favor by misreporting
