A Sensor Network with Embedded Data Processing and Data-to-Cloud Capabilities for Vibration-Based Real-Time SHM

Algorithm 1

Data collection algorithm.

1: procedure startSensor(address: int)

2:  command ← new AlwaysRunCommand

3:  send(address,command)

4:  waitForAck(address,TIMEOUT)

5: Init loop:

6: for all sensor address do

7:  startSensor(address)

8: Main loop:

9: for all sensor address do

10:  command ← new GetAccCommand

11:  send(address,command)

12:  data ← read(TIMEOUT)

13:  ifvalid(data) then

14:   send(address,ACK)

15:   acc ← decode(data)

16:   timestamp ← decode(data)

17:   sendToDB(address,acc,timestamp)

18:  startSensor(address)

19: gotoMain loop.
