Several methods exist for the assignment of trust to the nodes present in a Wireless Sensor Network (WSN). In this paper we develop a new algorithm for calculation of trust of individual nodes using both Direct and Indirect Trusts and thereby use the calculated trusts for determination of the different route trusts (RTs) to the Base Station. We present a link state routing protocol based on trust which protects the WSN against routing attacks by eliminating the un-trusted nodes beforehand. It then forms the routes and finds the best trustworthy route among them by comparing the values of all the calculated route trusts as for each and every route present in the network. This paper also shows the advantage of inclusion of Indirect Trusts in addition to the Direct Trusts. Finally, we compare our work with the most prevalent routing protocols and show its benefits over them.
