Query: A Trust Management Scheme for IoT-Enabled Environmental
  Health/Accessibility Monitoring Services   One rapidly growing application of Internet of Things (IoT) is the protection
of public health and well-being through enabling environmental monitoring
services. In particular, an IoT-enabled health/accessibility monitoring service
(HAMS) can be consulted by its users to query about the status of different
areas so as to optimize their trip throughout a geographic region. Given the
high cost associated with a vast deployment of totally trusted information
sources, the IoT-enabled monitoring services also subsist on citizen engagement
and on (possibly untrusted) users' sensing apparatus for data collection.
However, trust management becomes a key factor in the success of such services
because they might be misled by malicious users through altered or fake sensor
data. In this paper, we consider a monitoring service, and propose a hybrid
entity/data trust computation scheme which relies on Bayesian learning to score
the users (as data reporters), and on Dempster-Shafer theory (DST) for data
fusion and for the computation of the trustworthiness of the data itself. In
order to provide resiliency against behavioral changes, the probability masses
used in DST are dynamically updated using the freshly estimated user scores as
well as the contextual properties associated with the reported data. We conduct
simulation experiments to evaluate the performance of our scheme. Compared to
prior work, the results demonstrate superior performance in terms of accuracy
and resilience against malicious behavior.
