Abstract
A method and system discovers a route in a wireless communications network including multiple nodes. A RREQ frame is broadcast by a first node. The RREQ frame is generated to discover a route. A second node receives the RREQ frame. The second node unicasts a PING frame to the first node to verify an integrity of a wireless communications channel between the first node and the second node. Then, the second node unicasts a RREP frame only if the integrity of the wireless channel is verified.
