Service Discovery between Multiple Home Networks

In this article we propose a gateway-based architecture for service discovery between multiple home networks across the Internet. The gateway deploys a proxy, which maps re-mote devices to local network using the gateway’s IP address and collects all services within the local home network and exchanges the list of local services with other gateways of remote home networks. When a local device queries some specific services, the gateway will answer it on behalf of re-mote devices if there are matched services. In addition, SIP is utilized for initiating, managing and terminating the inter-communication between multiple home networks while TLS is used to protect the critical user data
