WSN is often deployed in unattended or even hostile environments. Therefore, providing security in WSN is a major requirement for acceptance and deployment of WSN. Furthermore, establishing trust in a clustered environment can provide numerous advantages. We proposed a light-weight trust model which considers data aggregation and communication failure due to wireless channels. It computes retransmission rate to get success, failed and uncertain value, and details the data in parameters to depend against attacks. With comparing our model with LDTS and Model using Trust Matrix, we conclude that our model has implemented a trade-off between detection rate and communication consumption.
