Methods and apparatus for event detection, propagation and localization using uwb impulse radios

Abstract

A distributed wireless sensor network includes two or more wireless nodes adapted for sensing a condition at any first node, first programming located within each node for transmitting a signal representing the sensed condition from the first node to another node, second programming located within each node for receiving the signal transmitted from any other node and for retransmitting a received signal representing the sensed condition along with additional data indicating the number of retransmissions of the signal between nodes.
