| dc.description.abstract | With the rapid development of mobile technology and subsequent mass adoption of mobile
devices, mobile crowdsensing (MCS) has gained a lot of research attention. In MCS systems, trust is a key
focus in the overall improvement in the participant uptake of the sensing tasks. The trust-based scheme of
MCS is studied to predict the damage level, the scores of quality-of-service (QoS), and the levels of qualityof-data (QoD) of MCS systems. Users can participate in MCS sensing based on trustworthy indicators that are
related to user experience and system reputation, as well as the knowledge obtained about the MCS systems.
This paper illustrates the establishment of user confidence during recruitment in MCS as it is very critical for
the success of MCS systems and proposes a simulation trust-based mechanism (SiTBaM) approach. The level
of MCS security is enhanced to protect the privacy of participants, so that participants can be assured that
the MCS system they are working with during sensing moment is trustworthy. The application of SiTBaM in
MCS is verified to yield better results as the simulations show that it offers higher QoS levels, QoD scores,
as well as low damage levels in the presence of any task or many malicious users. These results were validated
through comparisons with other schemes. | en_US |
