Confirming security to all individual nodes present in wireless network is ensuring the overall network security. The secure wireless network is needed many real time field-oriented applications. In the geographical fields, the network contains one or more sensor nodes. This network is called as Wireless Sensor Network (WSN). Due to the vulnerable medium condition and resource limitation of WSN, the lightweight security or Intrusion Detection Systems (IDS) are required. The securely selected watchdogs act as IDS agents to monitor the network-level activities of each node in the network. To protect WSN, enough rate watchdogs are needed around the network. This proposed system identifies the issues in the selection mechanisms of watchdog-based IDS in WSN. This work proposes novel secure watchdog selection procedures in WSN to increase watchdog availability ratio against different types of attacks. In this proposed mechanism, use various lightweight multi-layer security providing procedures.
