    Abstract
    Maximum achievable rates of cooperative sensors communicating
    with a mobile access point are considered for the case when some
    sensors may be misinformed with erroneous messages. Depending
    on the presence of polling channels and/or energy constraints, three
    system configurations are analyzed and their maximum achievable
    rates derived. It is shown that, when there is a polling channel and
    no energy constraint, the maximum achievable rate is the same as
    that when there are no misinformed sensors. In the absence of polling
    channels, however, there is a loss of achievable rate as a function
    of the probability that a sensor is misinformed. Results are extended
    to multiple simultaneous transmissions and in the presence of
    channel fading.
