A common technique used in routing protocols for ad hoc wireless networks is to establish the routing paths on-demand, as opposed to continually maintaining a complete routing table. A significant concern in routing is the ability to function in the presence of byzantine failures which include nodes that drop, modify, or mis-route packets in an attempt to disrupt the routing service. We propose an on-demand routing protocol for ad hoc wireless networks that provides resilience to byzantine failures caused by individual or colluding nodes. Our adaptive probing technique detects a malicious link after $\log n$ faults have occurred, where $n$ is the length of the path. These links are then avoided by multiplicatively increasing their weights and by using an on-demand route discovery protocol that finds a least weight path to the destination. } }
