What kind of resource management can use serverless at the edge?


I am a new researcher on serverless and would utilise it as a supporting technique in resource management at the edge.
Resource management compromises: resource discovery, allocation, offloading, provisioning, auto-scaling, placement and so on. But I have not had a clear target so far and am looking to justify the utilisation of serverless at the edge. In fact, how can what is the application/benefit of serverles there? My use cases will be delay-sensitive IoT applications and the IoT devices will be energy-limited.
Thank you in advance for your tips.
