A wireless sensor networks (WSN) is a distributed self-directed sensor nodes to cooperatively monitor the physical and environmental conditions within their vicinity. Trust becomes more important for autonomous sensor nodes deployed in hostile and military environment. The trust in WSN poses greater challenges of the system and the challenges are reliability, security, mobility ,faultTolerance and other attributes of trust worthy system.This paper introduced a new approach for the validity of the trust management to achieve the full trust worthiness of the networks. So this paper solves the problems of security issues related to both clustered and layered architecture sensor network and provide the high fault tolerance functionality to the sensor nodes
