System and method for communicating alarm conditions in a mesh network
First Claim
1. A method for a plurality of satellite nodes coupled to a sensing device or an actuator and logically dispersed around an access node to wirelessly communicate alarm conditions, comprising the steps of:
- accessing an alarm condition detected at a first satellite node;
preparing an alarm message for communication to the access node that includes an alarm code corresponding to the alarm condition and an address indication for the first satellite node;
receiving one or more alarm messages from one or more satellite nodes logically further from the access node than the first satellite node, wherein alarm codes contained in the one or more received alarm messages are filtered and compared to the alarm code of the prepared alarm message for the first satellite node;
including with the prepared alarm message for the first satellite node a sender address for each received alarm message containing an alarm code that matches the alarm code of the prepared alarm message for the first satellite node; and
transmitting the prepared alarm message from the first satellite node containing the one or more sender addresses to the access node.

Abstract
Each of a plurality of satellite nodes coupled to a sensing device or an actuator and logically dispersed around an access node are configured to wirelessly communicate alarm conditions. A first satellite node detects and accesses an alarm condition and then prepares an alarm message containing an alarm code corresponding to the alarm condition and an address indication. The first satellite node may thereafter receive alarm messages from other satellite nodes logically further from the access node than the first satellite node. Alarm codes contained in the received alarm messages are filtered and compared to the alarm code of the prepared alarm message. The first satellite node includes a sender address in the prepared alarm message for each received alarm message containing an alarm code that matches the alarm code of the prepared alarm message. The first satellite node transmits the prepared alarm message to the access node.

9. A radio node configured to communicate with one or more other radio nodes logically dispersed around an access node and report detected alarm conditions to the access node, comprising:
-
an input coupled to a reporting device, wherein the reporting device is configured to communicate an alarm condition to the input;
a processor coupled to the input configured to access the alarm condition according to logic contained in memory coupled to the processor;
logic contained in memory configured to prepare a first alarm message that includes an alarm code corresponding to the communicated alarm condition and an address indication for the radio node;
an RF transceiver coupled to the processor configured to transmit and receive communications, wherein the processor is configured to determine if one or more additional alarm messages are received by the RF transceiver;
logic contained in memory configured to combine a sender address portion of each additional alarm message having an alarm code that matches an alarm code of the first alarm message; and
logic configured to cause the RF transceiver to transmit the first alarm message to the access node. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
