||Distributed Detection with Channel Selection in Sensor Networks in the Presence of Eavesdroppers|
|Date of Defense
||Wireless Sensor Networks
||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.
