The following scenarios were evaluated in the active connected state, as shown in the table. No additional application activity or data exchange occurs.
| State | CoAP acknowledgment | Battery |
|---|---|---|
| Idle SED connected to the parent | No | Useful in predicting base battery life |
| Short CoAP NON frame sent every 30 min to parent | No | Estimate battery life for the simple light switch application |
| Short CoAP CON frame sent every 30 min to parent | Yes | Base estimation for the simple sensor |
| Long CoAP NON frame sent every 10 min to the parent | No | Base estimation for the more advanced switch |
| Long CoAP CON frame sent every 10 min to the parent | Yes | Base estimation for the more advanced sensor |
| Long CoAP CON frame sent every 1 min to the parent | Yes |
Base estimation for the more advanced sensor Shows impact of increasing messaging frequency |
