Optimize on Data Correlation of Sensor Nodes with Adaptive Fault-tolerant Algorithm☆

A-SMAC protocol based on sensor node data traffic dynamic adjusting node listen and sleep time. Based on A-SMAC protocol, sensor nodes sent out the underlying error decisions .In this paper, we propose an adaptive fault-tolerant algorithm (AFTA) of node. According to the results of fault tolerant judgment, use of A-SMAC protocol dynamic adjusting node listen and sleep time, realize the combination of data judgment and node dynamic listening. Our experimental results show that the AFTA outperforms the Bayesian algorithm and exhibits strong fault-tolerant capabilities and less energy consume.
