The significant act of its intelligent behavior make it useful in important applications like military and disaster management. It is a highly distributed large scale system in which malicious nodes planted by strangers impose a threat for confidentiality and integrity along with denial of service in certain applications. To combat such situation security algorithms are incorporated in the context aware middleware arranged in the sensor nodes. Such a provision has got the drawback of more energy and overhead needs along with higher cost. In the method proposed here, a cost effective agent node based middleware is organized to identify malicious nodes and inform the friendly sensor nodes about the details of them. The agent based secured WSN (ABSWSN) system is simulated to establish its performance for overcoming the effect of the presence of malicious node. The agent based system performs better as far as processor time utilized and packet loss, giving higher throughput.
