Mobility is main problem in MANETs. Node movement increases the chance for potential contactors to gather more trust information and evidence, thus enlarging the scope of reputation qualified candidate nodes popularly. Micro mobility and macro mobility are two movements the users have to consider. So checking mobility is main important. Existing system uncertainty deeply impacts a node's anticipation of others' behavior and decisions during interaction, after defining a way to reveal and compute the uncertainty in trust opinions the authors consider mobility, one of the important characteristics of MANETs, to efficiently reduce uncertainty and to speed up trust convergence.
