Abstract [en]

Home automation systems are collections of smart devices that enable various functions within a house or building, such as light and plug control, energy monitoring, temperature metering, air conditioning and heating, etc. Usually, these devices are smart sensors, that are implemented with low power communication protocol like ZigBee and 6LoWPAN and only can be controlled from an Internet gateway. Nowadays, there are lots of home automation products on the market for customers. User can use application on smart phone to control the products they bought. The control command can go through a cloud-based server and be directed to the corresponding gateway, and finally reach to the sensor devices, which is referred to as "cloud-based mode" system. However, this single mode is not effcient under some circumstances where the Internet is not enabled or allowed. In this thesis work, a hybrid system architecture is proposed, implemented and evaluated, which include both stand-only and cloud-based mode. It offers a quick connection when user's smart phone and the sensor gateway are in the same private network. The proposed doublemode system architecture fits user's need and provides high reliability.

Abstract [sv]

Hemautomationssystem är smarta enheter som möjliggör olika funktioner i ett hus eller en byggnad, såsom kontroll av ljus och uttag, energiövervakning, temperaturm ätning, luftkonditionering och uppvärmning, etc. Dessa enheter är vanligtvis smarta sensorer, implementerade med lågeffekt kommunikationsprotokoll som ZigBee och 6LoWPAN som endast kan styras via en Internet-gateway. Numera finns det era hemautomationprodukter på marknaden. Användaren kan med sin smarta telefon styra sina produkter. Kommandot går via en molnbaserad server och vidarebefordras till motsvarande gateway, kommandot når slutligen till sensoranordningarna, även kallat "molnbaserat läge". Detta "molnbaserade läge" är inte effektiv under vissa omständigheter där internetanslutning ej är tillänglig. I detta avhandlingsarbete föreslås, genomförs och utvärderas en hybrid systemarkitektur som inkluderar både stand-only och molnbaserade läget. Detta erbjuder en snabb anslutning när användarens smartphone och sensor gateway är pår samma privata nätverk. Den föreslagna systemarkitekturen passar användarens behov och ger hög tillförlitlighe
