A Cloud-Based Architecture for Home Network System

Managing a home server within individual house is a major obstacle to practical use of home network system (HNS). Delegating the home server to a cloud is a promising approach. However, the conventional multitenant SaaS-based solution has the following risks among different households: security/privacy violation, failure propagation and insufficient resource demand. In this paper, we propose a novel cloud-based architecture for the home network system that achieves security isolation, fault isolation and resource isolation. Specifically, we first create a virtual home server for every household using IaaS. On top of every virtual home server, we then create additional virtual machines, each of which contains a single service or application. Finally, using dynamic scaling, we allocate resources needed for individual virtual home servers. Based on the idea, we construct the proposed architecture by three layers: HNS Lite, House Cloud and Service Provider.
