Abstract
Methods and systems for performing a round trip time determination between two devices are described. An example method may include publishing, over a wireless network interface by a first device within a neighbor aware network (NAN) cluster, a schedule that invites devices within the NAN cluster to request, within a time window, to perform a round trip time (RTT) determination with the first device. The schedule may indicate that the time window begins at a time offset from a NAN discovery window and ends after a predetermined period of time has elapsed. The method may also include receiving a request, from a second device within the NAN cluster, to perform the RTT determination with the first device. The method may also include performing the RTT determination with the second device.
