Abstract : Wireless sensor network consists of set of source, sink nodes and communication devices to interact without any support of the infrastructure. Unlike wired networks, the challenges faced in mobile ad-hoc networks possessed such as security design, network infrastructure, stringent energy resources and network security issues. The need to these security issues is much focused in overcoming the challenges in WSN. Here the perpetual work focuses on the secure communication using a novel defense framework named role based control model is proposed to analyze the network flow and to identify the misbehaving nodes. The communication is performed based on the cluster of immense size these confided in node(s) will most likely be passing on together, in the meantime allowing or section entry/correspondence of the unauthorized node(s) to continue keeping up a constant, tied down, dependable communication of versatile nodes. The simulation is performed using network simulator where the network parameters such as throughput, packet delivery ratio, delay and packet loss are analyzed to identify the malicious nodes.
