Abstract- Research problems are to enhance an Intrusion Detection System (IDS) of a clustered HWSN to prolong its lifetime operation in the presence of unreliable and malicious nodes. Also, to address the energy consumption and QoS gain in reliability, delay and security with the goal to maximize the lifetime of a clustered HWSN while satisfying application QoS requirements in the context of multipath routing. The proposed research is a highly scalable cluster-based hierarchical trust management protocol for wireless sensor networks (WSNs) to effectively deal with selfish or malicious nodes. The proposed work consider multidimensional trust attributes derived from communication and social networks to evaluate the overall trust of a sensor node. System describes a heterogeneous WSN comprising a large number of sensor nodes with vastly different social and quality of service (QoS) behaviors with the objective t
