Wireless Sensor Network (WSN) are 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 survey paper various security mechanisms are discussed to find malicious nodes and to do secure routing. In the proposed work, our main aim is to find the trusted node by using trust model and the malicious report is checked, and routing is done. It provides the security features with minimum overhead and energy efficiency. Trust-aware routing protocol plays a vital role in security of wireless sensor networks (WSNs), which is one of the most popular network technologies for smart city. However, several key issues in conventional trust-aware routing protocols still remain to be solved, such as the compatibility of trust metric with QoS metrics and the control of overhead produced by trust evaluation procedure. we first analyze features of common attacks on trust-aware routing schemes, Then, specific trust computation and trust derivation schemes are proposed based on analysis results. Finally, our design uses the combination of trust metric and QoS metrics as routing metrics to present an optimized routing algorithm. We show with the help of simulations that TSSRM can achieve both intended security and high efficiency suitable for WSN-based networks.
