Wireless Sensor Network (WSN) has now huge scope for research and application development but sensor networks are vulnerable to different attack. Hence security is key issue while using sensor networks. Identity deceptions attacks are hard to detect attack e.g. sinkhole attack, wormhole attack, and Sybil attacks. Trust aware routing framework based on trust values of sensor nodes is proved effective for preventing Identity deception attacks. But Denial-Of-Service (DOS) attacks or link failure conditions are not discussed in existing system. This paper focuses on the study behavior of trust aware routing framework with backup path generation algorithm for link failure recovery.
