Claim:
1. A method of emergency response on a network of Bluetooth low energy (BLE) beacons, the method comprising: broadcasting corresponding identification information from each of at least three of the BLE beacons over the BLE network; receiving a distress message including a location of a user device at one of the BLE beacons over the BLE network from the user device after the user device received the broadcasted corresponding identification information from the at least three of the BLE beacons and generated the location of the user device using the received corresponding identification information; retransmitting the distress message over the BLE network to a master BLE beacon, the BLE beacons being ordered by proximity to the master BLE beacon; receiving a retransmitted second such distress message at the one beacon over the BLE network from a second beacon of the BLE beacons; retransmitting the second such distress message over the BLE network when the second beacon is further from the master BLE beacon than the one beacon is from the master BLE beacon; and not retransmitting the second such distress message over the BLE network when the second beacon is closer to the master BLE beacon than the one beacon is to the master BLE beacon.
