Research on data management in mobile ad-hoc networks
focuses on discovering sources and acquiring information.
Mobile devices assume answers to be correct
and do not verify the veracity of the information
or the providers. This assumption is suitable for most
client-server environments; however, peer-to-peer environments
lack the intrinsic stability of "anchored"
sources. In mobile ad-hoc networks, sources may provide
faulty information, which can lead to incorrect conclusions.
Consequently, devices need a mechanism to
evaluate the integrity of their peers and the accuracy
of peer provided information. To address this problem
we propose a query processing model that relies on distributed
trust and belief. Each device maintains and
shares beliefs regarding the degree of trust it has for
its peers — where trust is determined by experience and
reputation. Additionally, each device associates a value
indicating its belief in the accuracy of the information
it holds. This knowledge is used by devices to determine
the reliability of query responses. We implement
our model in GloMoSim and provide experimental results
for different combinations of trust and accuracy algorithms.
