Abstract – Wireless Sensor Networks (WSNs) are widely used in different types of applications. Due to the open medium of these networks, they are vulnerable against the intrusions or attacks. Any adversary can have the opportunity to insert their attacks to dump the performance of the sensor nodes or the overall network. To identify the adversaries, Watchdog nodes are selected based on different mechanisms with limited assumptions. Once the adversary has the internal network knowledge, then the conventional monitoring mechanisms could be useless. This work provides resilient solution over these critical issues by selecting the watchdog nodes using On-Demand Dynamic Monitoring and Routing Protocol (ODDMRP) with secret key management techniques.. Here, the watchdog node selection processes and the monitoring processes are kept secret against any type of adversary or against various attacks.
