  • Abstract In recent years, wireless sensor networks are widely used because they comprised a large
    number of low-cost, low-power and miniature sensors. In wireless sensor networks, the sensors
    need to deal with the important and complex information, moreover, they transmit across a
    wireless communication network to legitimate users. Since most of the sensors transmit message
    in open area, the eavesdroppers are easy to tap in the transfer process. Owing to each channel
    environment is different in reality, the fusion center must have the ability of channel selection
    to ensure that correct information is received.
    In this thesis, the channels considered from sensors to receiver are Rayleigh Fading Channel.
    When sensors transmit message, the FC will prioritize in choosing the better channel gain to
    receive signals. Likelihood Ratio Test is then used to analyze the received data in FC and
    achieve the smallest FC’s error probability while maintaining the eavesdropper’s error probability
    not lower than a required value.
