In one embodiment, a method comprises: generating, by a transmitting network device, a hashed source media access control (MAC) address and a hashed destination MAC address based on hashing a MAC address of the transmitting network device and a destination MAC address of a destination wireless network device, respectively, relative to an epochal transmission sequence value; and transmitting a data frame at a time slot associated with the epochal transmission sequence value, using the hashed source MAC address and the hashed destination MAC address, to the destination wireless network device.
