The lightweight algorithm shall be lightweight to adhere to IoT Sensor Node low computational power and low energy consumption. The lightweight algorithm was designed specifically for mitigating a DoS attack on IoT Sensor Node. The proposed algorithm for IoT Sensor Node shall prevents the abnormal energy consumption by monitoring, calculating and evaluating energy drop from each cluster nodes based on few condition.
In abnormal cluster node behavior, if energy drop reaches 3% in less than 20 minutes anomalies packet will be analyzed, and abnormality is classified as an attack. Anomalies packets will be dropped, and the affected cluster will switch to a different wireless network to terminate the outbreak. There are following conditions after that. If the voltage drop is less than 3% within
20 minutes, packets will be transmitted as usual. If there is energy drop reaches 10% in less than 30 minutes, the abnormal is classified as an attack, so the anomalies packet
will be dropped, and the cluster will switch to a different wireless network. If not, the testbed operates as usual. Then, if the energy drop reached 50% in less than 185 minutes, the
algorithm will detect the situation as abnormal behavior. The anomalies packets will be dropped, and the IoT Sensor Node will switch to a different wireless network
