Abstract:
1. A method comprising: transmitting, via a transmitter, a plurality of transmit pings at a transmit interval, the transmit interval corresponding to a time between transmission of each transmit ping; listening, via a receiver, for a live ping, the receiver configured to be turned on at a beginning of an assess interval, and off at an end of a detect duration, the assess interval corresponding to a time each packet in the live ping is spaced apart multiplied by an amount of packets in the live ping, the detect duration corresponding to the time each packet in the live ping is spaced apart plus a transmit time, the transmit time corresponding to a time required for a packet to travel from one device to another; receiving, via the receiver, at least one packet from the live ping; delaying, after receiving the live ping, transmission of a new ping for a delay duration, the delay duration corresponding to an amount of time determined, at least in part, by a counter value of a packet of the live ping, the delay duration determined using the counter value of the packet of the live ping, wherein the counter value is included in the packet of the live ping and corresponds to a position of the packet within the live ping; and transmitting, via the transmitter, new pings at the transmit interval.
