1. The Network Aware IoT Service at Edge Guoxi Wang

2. Background : Cloud-based IoT Application Cloud-based IoT Application: Easy to develop and deploy on a large scale Convenient to integrate with other services Pitfalls for Today’s Cloud-based IoT Application: Latency Security and Privacy Guaranteed QoS ….

3. Resilience Problem of Cloud-based IoT Problem: Failure of cloud server or the link to the cloud server will cause the failure of IoT clients Possible Solution: Deploy backup server at network edge or other locations Client devices detect the failure and then switch to the service at backup server Limits: Constrained computing resource Limited knowledge Some deployed nodes may not even possible to modify.

4. 1.Failure Detection / Traffic Monitoring 2.Sensor Data Redirection 3.Data Processing at Edge Server LAN Cloud Edge Server SDN Controller First Attempt : Backup Sensor Data Storage at Edge

6. A framework for Network Aware IoT Service at Edge

7. Possible Works Network metrics monitoring in SDN architecture Seamless cloud service to edge service migration and vice versa Implement current cloud-based application in cloud server - edge server - client architecture …..
