System and Methods for Monitoring Security Zones
First Claim
1. A security zone monitoring system comprising:
- a plurality of sensor nodes dispersed in the security zone, wherein each sensor node transmits a communication without protocols other than a rudimentary language or signal to alert its neighboring sensor nodes when the sensor node detects an intrusion into the security zone and the alerted neighboring sensor nodes that also detect the intrusion transmit the communication to alert their neighboring sensor nodes, the communication continuing to be transmitted by and through the plurality of sensor nodes that detect the intrusion until the intrusion is no longer detected, whereby an increase in the communication transmissions between the plurality of sensor nodes detecting the intrusion increases a total power density in the security zone; and
a transceiver located remotely from the security zone for detecting and localizing the increase in the total power density and for providing an alert of the intrusion.

Abstract
A security zone is monitored for intrusion detection by dispersing therein a plurality of sensor nodes that, when an intrusion is detected, communicate with their neighboring sensor nodes without protocols other than a first tone. As the intrusion is detected by more sensor nodes, there is an increase in sensor node transmissions and, hence, an increase in the total power density in the security zone which is detected by a remote monitor for detecting and localizing the intrusion and providing an alert. In addition, certain of the sensor nodes also transmit a continuous second tone received by other sensor nodes. When an intrusion occurs, the transmission is blocked causing the receiving nodes to transmit the first tone to alert neighboring nodes.
