Trustworthy Route formation Algorithm for WSNs

This paper introduces a new algorithm for the formation of trustworthy route from source node to Base Station (BS) for secure routing of messages in Wireless Sensor Networks (WSNs). This algorithm process the information given by the Trust dependent Link State Routing Protocol which is improved version of our Routing Protocol presented in [1] Direct Trust dependent Link State Routing Protocol based on Geometric Mean (GM) of the QoS characteristics which allows the trusted nodes only to participate in the routing. Execution of this algorithm at any node, gives different trusted routes to the BS with different route trusts by filtering the un-trusted nodes on the basis of trust metrics levels. The source node selects the best trustworthy route among many trusted routes given by the neighbor nodes based on neighbor nodes trust levels and the route trust levels of different routes given by them. The newly formed trustworthy route from source node to BS will be the best trustworthy route without considering the malicious/selfish nodes.
