Managing Trade-off Between Subscription Load and Latency in Vehicular Edge Platform
Keywords:Edge computing, Publish/Subscribe, MQTT, IoT, Vehicular platform
Adding connectivity to vehicles is attracting much attention toward developing smarter vehicles such as autonomous cars. To obtain and utilize real-time information from vehicles, techniques that combine the concept of edge computing and publish/subscribe messaging model have been proposed. However, there is an issue that the increase in the number of edge servers imposes a heavy load upon a subscriber for managing connections to them. To address this issue, we propose an edge-based platform with the functionality of adjusting the number of connections to edge servers. Experimental results clarify the trade-off characteristic between subscription load and latency.
