Integration of trust in routing mechanisms already prevalent in Wireless Sensor Networks (WSN) has become an interesting research area of late. Several methods exist for the assignment of trust to the nodes present in a WSN. However the real challenge lies in proper integration of this trust to an existing routing protocol for the synthesis of a trust-aware routing algorithm. In this paper we try to take the help of Geometrical Mean based indirect trust evaluation mechanism for calculation of trust of individual nodes and thereby use the calculated trusts for determination of the different route trusts (RTs). We present a link state routing protocol based only on these indirect trusts which forms the routes and finds the best trustworthy route among them by comparing the values of all the calculated route trusts as for each route present in the network. We have developed three algorithms related to this and have shown their merits. Finally, we compare our work with similar trust integrated routing protocols and show its advantages over them.
