The latest advances in technology have facilitated the emergence of Wireless Sensor Networks (WSNs) as a promising technology. Because of their wide range of applications in industry, environmental monitoring, military and civilian domains, WSNs have become one of the most popular topics for research and development. The sensor nodes are low in cost and are simple in architecture. Wireless sensor networks are being employed in security-critical applications. However, their inherent characteristics make them prone to various security outbreaks that can negatively affect data collection. The current project presents an active detection-based routing scheme for WSNs, which can quickly create numerous detection routes as well as obtain nodal trust and thereby improve data security. Simulation results show that this scheme can detect Black Hole attacks, protect against them, and conserve energy, thus improving the network lifetime.
