Performance evaluation of a satellite communication-based mec architecture for iot applications

HIGHLIGHTS

SUMMARY

    Enabling the additional MEC functionalities should reduce even more the impact of sensor traffic on the satellite link, due to: 1) the reduction of the amount of data that have to reach the 3780 core MQTT broker and then go back to the edge MQTT clients owing to the edge MQTT brokering functions; 2) data compression and aggregation functions. The uplink bandwidth is reduced to about 50% (from 47.9 to 24.6 kb/s), while the number of sensors is reduced to 32% (from 5000 to 3400, which are both real-time and . . .
