In this paper, we proposed a novel routing scheme for Wirel ess Sensor Networks which is robust and can extent the network lifetime by eliminating the error-prone nodes and nodes with low amount of energy. Advanced andcomplex WSNs need to work for a long time, but an efficient routing is needed to achieve this goal. In our proposed routing algorithm, head nodes ofany cluster check the malicious nodes and remove them from the selection of sensors and recover the lost path based on trust model. Simulation resultsshow that Reliable Routing by Base-station Investigation (RRBI) can have great influence in the reliability and network stability and prolong the lifetimeof WSNs, perfectly
