Wireless sensor networks (WSNs) are always plagued by serious security issues. A number of trust-based routing methods have been developed, and they are the key to improving wireless network effectiveness. However, due to unreliable wireless communication networks, they remain have significant drawbacks like low energy reserves, vulnerability to physical capture, and insufficient security against numerous attacks. Because of the built-in vulnerability of WSN to assaults, security is a necessity in WSN and is incredibly difficult to provide. A WSN node that is involved must transport data to nearby nodes to avoid a disaster in the event of a node attack. Recently, trust mechanisms have increasingly been viewed as the best method for reducing security issues in WSN. The goal of this study is to examine several Security routing methods and techniques for wireless sensing connections that are already in use and rely on trust. The technique, trust metric, benefits, drawbacks, and complexity of the idea behind the current trust mechanism are all examined. The security resilience of different trust types towards attacks are also examined in the final stage.

An efficient system for identifying unauthorized nodes and their behaviors in WSN is included in Trust Models. The neighboring nodes can utilize the trust knowledge to avoid the misbehaving node after it has been identified as such. The paper surveys the recent advancements in secure trust based routing in WSN. Various parameters have been considered for the trust based secure routing. The trust based mechanisms, comparisons, trust index calculations have been depicted in this paper. The paper can be extended by considering the trust based routing for multimedia content as well. This paper describes the work for physical information or static content. In future, the security can also be given to large video, audio and image files.
