1. A distributed self-synchronizing, pulse coupled wireless sensor network, comprising:
- more than two self-synchronizing, pulse coupled wireless nodes adapted for sensing a condition at any first node wherein each wireless node includes a pulse coupled oscillator connected to self-synchronize with pulse coupled oscillators in other wireless nodes;
first programming located within each node for transmitting a signal representing the sensed condition from the first node to a second node;
second programming located within each node for receiving the signal transmitted from any first node and retransmitting a received signal to a third node along with additional data indicating the number of retransmissions of the signal between nodes,wherein the more than two wireless nodes use pulse coupled synchronization between pulse coupled oscillators in separate wireless nodes having a synchronization time-frame repetition period, which time-frame repetition period is divided into predetermined number of sequential data bins, and further wherein the number of retransmissions is indicated by the selection of a sequential data bin for a single pulse transmission.

11. A method of communication for a distributed, self-synchronizing, pulse coupled wireless sensor network, comprising the steps of:
-
synchronizing separate nodes in a distributed, pulse-coupled wireless sensor network using synchronization pulses transmitted between the separate nodes to synchronize a pulse coupled oscillator in each node; sensing a condition at any first separate node in the sensor network; transmitting a signal representing the sensed condition from the first separate node to a second separate node; retransmitting the signal when received at the second separate node to a third separate node along with additional data indicating the number of retransmissions of the signal between nodes; and repeating the step of retransmitting to propagate the signal through the network, wherein the steps of transmitting, retransmitting and repeating are performed using a time-frame repetition period between synchronization pulses, which time-frame repetition period is divided into a predetermined number of sequential data bins, and further wherein the number of retransmissions is carried in each retransmission by the selection of a sequential data bin for a pulse transmission. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
