Large-scale and real-time remote control architecture for home appliances

Abstract

This paper presents the system architecture of bidirectional communication for remote control of home devices. The system architecture is designed in view of the requirements such as feasibility for typical home users, scalability, and responsiveness of interactive operations. The proposed architecture, named Mediation architecture, features use of WebSocket and the hosting of connections from a home device and a user application at the same server to achieve low-latency communication. The experimental results obtained in a testbed environment indicate that the proposed system provides low latency that is practical for an actual service.

A Cost-Effective Method to Keep Availability of Many Cloud-Connected Devices

“…Referring to our previous work [4], we describe a cloudbased remote control system and discuss pros and cons of the cloud-based approach. Fig.2 shows the connection mediator architecture for the cloud-based remote control system that is proposed in our previous work.…”

“…A cloud-based remote control system is one of the candidate solutions for these requirements. It adopts an effective messaging protocol (e.g., WebSocket [10] or MQTT [11]) and uses message brokers (hereafter simply called brokers) for relaying messages between controllers and devices [4]- [6] (Fig.1). The system makes devices keep connections to message brokers for NAT traversal and allows controllers access the devices through the connections.…”
