Adopting AR/VR technology on smart retail services is gaining more momentum with the progress in indoor map scanning technology and the research on AI deep learning algorithms. In this paper we propose the use of a Fog computing node to generate an AR/VR view of the real store on a web page. The customers can then use the service robot to view the merchandise in the real store via the web and make purchases. Since the service robot is a precious resource on the AR/VR business model, we develop an auction method to optimize the customer satisfaction and the owner satisfaction in terms of customer waiting time and the average number of transactions that are assisted by the service robot respectively. We demonstrate that the auction method is a critical part in the AR/VR smart business services when the number of service robots is much less than the number of active customers from the web and that it performs better than the standard preemptive method.

Fog computing has been widely adopted to meet the performance of explosive growth of IoT applications. In both 5G and IoT applications, low latency and ultra-reliable communication are two key features which cloud-based only architecture cannot meet those performance requirements. Fog computing which adds a hierarchy of elements between the cloud and endpoint devices can meet those requirements in a secure, high performance, open, and interoperable way. To validate whether future fog node products can meet trusted computing criteria and performance requirements or not, a common testbed is necessary. In this paper, we will first discussion the security practice (the fundamental pillar of OpenFog architecture) required for future testbed designs. National Chiao Tung University (NCTU) is leading to attempt to provide Security-as-a-Service (SECaaS) in NCTU testbed based on 4G wireless networks and two other fog enabled testbeds provided by ITRI's smart lamp posts testbed and Shanghai Tech's software defined (SD) LTE fog nodes testbed are also discussed for rapid prototyping of vertical industry applications. Two use cases, indoor autonomous vehicle and BATS codes multihop wireless will also be presented as the potential examples for testbeds.
