Abstract Sensor nodes in WSN play a vital role in communication, IoTs and many other emergencies too. However, the energy consumption of nodes is a major setback to these, which incites various malicious nodes/attacks. This article studies and presents the solution to Vampire attack‐ one of those kinds of attacks. It depletes the energy by route elongation of data transmission. This article has suggested a novel two‐fold mechanism to detect the attack by integrating co‐operation trust mechanism and the mitigation of the attack by selecting the secure route by policy gradient‐deep reinforcement learning. The designed protocol also ensures the selection of a secure hop even in the presence of the vampire attack. The results are compared with various other existing state‐of‐the‐art schemes and have improved the detection ratio by 20% compared to the forecasting methods applied for detecting the vampire node's behavior. The network lifetime has also improved by 3% than the benchmark dynamic source routing.
