Abstract
A system for transmission of incident information includes maintaining a table of RSSI values for a plurality of stations. When an incident is detected, the system first sends a broadcast packet with incident information, and next sends a unicast packet to any station below a particular RSSI threshold until the unicast packet is acknowledged or a retransmission interval passes.
