Abstract
The present invention provides a bandwidth efficient system and method of measuring the range between nodes () in a wireless communications network () with one-way data transfer, where each node () periodically transmits a message that contains information regarding neighboring nodes () from which any prior messages have been received by the transmitting node (). A node () receives the messages transmitted from neighboring nodes () in the network (), and records the times of arrival of the received messages. The node () receiving those messages can thus determine the respective distances between itself and the neighboring nodes () based on the respective time of arrivals of the received messages and the respective information included in the respective messages.
