Therefore, it is not uncommon for sensor networks to have malfunction behaviour, power shortage or network failure. To address this issue, we proposed a new scheme based on Causal Model Method (CMM) which applies fault sources analyzer for component-level fault diagnosis in wireless sensor networks. Our new method consists of three phases to define the node failure sources as “collect, classify, and correct”. Once the fault source has been classified, CMM mechanism will enable reconfigure pro
