Abstract :
Data aggregation is a necessary choice of the resource-restricted wireless sensor networks, security-sensible projects in wireless sensor networks are easily threaten by fabricating or tampering data out of nodes during data aggregation. To guarantee the authenticity and reliability of data resulting from aggregation, a secure model of data aggregation for wireless sensor networks is built based on evaluation of creditability of nodes, to compute the creditability of nodes based on statistics theory, the reliability of data out of neighboring nodes is evaluated according to its creditability. The simulation conclusions approve that the model is effective and the result of data aggregation is reliable.
