Abstract
The present invention discloses a distributed information source estimation method based on cooperative communication, which comprises the following steps: the fusion center selects a relay node with the best channel quality from a plurality of sensor nodes, according to the current channel quality between each sensor node and the fusion center; said fusion center carries out transmission power distribution on each sensor node, according to the observation quality of each sensor node towards an information source and the current channel quality between each sensor node and the fusion center; each sensor node judges whether it is a relay node or not; the sensor node directly transmits the observation information obtained by observing the information source to said fusion center; the sensor node transmits the observation information obtained by observing the information source to said fusion center.
