Table 1 Comparative analysis of terminal access methods
From: Alarm method of communication intelligent manhole cover based on multiple event fusion
Web platform | IoT cloud platform |
|---|---|
Heartbeat packets every 2Â min and waste resources | The terminal does not send the heartbeat packets and only one business interaction within 24Â h is required, save the power consumption |
The network congestion and packet loss for the massive device access | It can avoid the congestion and improve the reliability of the IoT systems |
There is no asynchronous execution between web platform and terminal, increase the overhead and decrease the efficiency | It can cache the commands and wait for the results, issue the commands by the aware of the terminal state and ensure the reliability |
