Wireless Sensor Network (WSN) is the emerging and challenging technology with low processing and battery power. Security becomes a major issue in WSN; because of its wireless nature it is prone to various types of attacks and losing of data packet. Secure routing is important to avoid this type of issues. In this paper, various security mechanisms are discussed to find malicious nodes and to do secure routing. In this paper, the authors' main aim is to find the trusted node by using trust model and the malicious report is checked, and routing is done using BFS. It provides the security features with minimum overhead and energy efficiency.
