چکیده

In wireless sensor networks, secure routing and trusted transmission of data through the nodes is one of the most challenging applications. In this paper, we are implementing the concept of trust management by using QOS metric estimation and the concept of Light weight trust management protocol is also introduced. The trust degree is calculated among the nodes by the method of direct and indirect trust computation with the help of neighbor’s recommendation and direct monitoring of packet forwarding process. The packets are transmitted only through the trusted nodes. The trust degree is calculated with the help of threshold value that is set to every nodes and the packet forwarding behavior. The nodes are said to be highly trusted node based on the trust degree value of the nodes. This method is implemented using Trust based QOS routing algorithm (TQR) .From this we can achieve the most efficient transmission among the network. Finally the performance is compared with AODV, Watchdog DSR and QAODV protocol. This will conclude that it can prevent attacks from the malicious nodes and increase the security level among the network
