Sensor node repairing is important for providing continuous sensing services. However, sometimes sensor nodes fail due to environmental interference such as attacks. Automatically replacing faulty sensor nodes in a sensor network may not be the course of action if the sensor network is under attack, because the attack will most likely disable the new nodes as well. In the extent of our knowledge, existing approaches tried to replace failed nodes with functional ones without examining whether the nodes failed due to some attacks. In order to study the efficient strategies for monitoring and repairing network behavior, we propose a framework for sensor nodes replacement that uses the mining technique in monitoring and repairing sensor nodes in wireless sensor network.
