Data reception stages of an end device.

Annotation of Figure 6b	Stages of Data Transmission/Reception	Brief Explanation
1	Idle time (Tidle)	Node is active, but the radio is not active. The nodes tend to stay in idle mode to save energy.
2	Data reception time (Trx)	Reception of the beacon message broadcasted from a coordinator.
3	Radio standby time (Tsb)	Radio stays in standby mode before sending a data request to a coordinator or any sender as it waits for backoff time and performs CCA.
4	Data transmit time (Ttx)	End node sends the data request to the coordinator/sender
5	Data reception time (Trx)	End node receives the ACK of the data request and goes to receiving mode and waits until data transmission is over
6	Data transmit time (Trx)	ACK is sent upon successful reception of the packet.
7	Sleep Time (Tsleep)	End node remains in the sleep mode before and after the reception of the data packet as defined by the experiment configuration
