Abstract
In one embodiment, a sensor device in a network detects an alarm condition. The sensor device generates an alarm message based on the detected alarm condition and waits for a delay whose length is inversely proportional to a distance between the sensor device and a downstream destination device for which the alarm message is destined. During the delay, the sensor device receives one or more additional alarm messages from one or more upstream sensor devices. The sensor device coalesces the one or more received alarm messages from the one or more upstream sensor devices with the alarm message generated at the sensor device, to form a coalesced alarm message, and transmits the coalesced alarm message downstream towards the downstream destination device, after expiration of the delay.
