Table 2 Events summary for SMED

From: Sleep/wake scheduling scheme for minimizing end-to-end delay in multi-hop wireless sensor networks

S. no event name Description
1. Initialization() This event is executed in the start, when node is initialized. It involves initialization of node parameter, some of which includes nodeID, initial residual energy, random location coordinates etc.
2. SN_W This is activated when a node's self timer expires. Senor node then changes its state from sleep to active state
3. SN_S This is activated when a node finishes sending/receiving data or self timer expires. Senor node then changes its state from active to sleep state
4. E_DETECT This event is activated when a node sense any event. It is a self message
5. SEND_MSG This event is activated when a node receives self message event E_DETECT. It involves sending send the data to the next hop neighbor using RTS/CTS/DATA
6. RECEIVE_MSG This event is activated when a node receives any message RTS/CTS/DATA. It involves establishing the communication with sender node and receives the data using RTS/CTS/DATA
7. End Timer An event triggered when the WAIT timer expires. It can be at the completion of any of timer event detection, sleep or wake timer
