AN ADAPTIVE RETRANSMISSION SCHEME FOR THE TYPE-BASED DISTRIBUTED DETECTION

摘要：

In the type-based distributed detection (TBDD for short) framework proposed recently, the type statistic of each sensor must be transmitted to a fusion center for making a final decision.The detection error probability using this approach is high when the transmission channel is highly noisy. Therefore, an approach combining TBDD with channel error detection was proposed to design a faulttolerant detection system in wireless sensor networks.When the fusion center detects the occurrences of transmission error, the sensor which has sent the received result will be asked to retransmit its type statistic by the fusion center. Simulation results show that the detection error probability can be effectively reduced through the retransmission scheme at moderate cost of traffic and amount of calculation.
