Abstract [en]

To enable high performance data management for sensor-based systems the system components in an architecture has to be tailored to the situation at hand. Therefore, each component has to handle a massive amount of data independently, and at the same time cooperate with other components within a system. To facilitate rapid data processing between components, a model detailing the flow of information and specifying internal component structures will assist in faster and more reliable system designs. This thesis presents a model for a scalable, safe, reliable and high performing system for managing sensor-based data. Based on the model a prototype is developed that can be used to handle a large amount of messages from various distributed sensors. The different components within the prototype are evaluated and their advantages and disadvantages are presented. The result merits the architecture of the prototype and validates the initial requirements of how it should operate to achieve high performance. By combining components with individual advantages, a system can be designed that allows a high amount of simultaneous data to be disaggregated into its respective category, processed to make the information usable and stored in a database for easy access to interested parties.

Abstract [sv]

Om ett system som hanterar sensorbaserad data ska kunna prestera bra måste komponenterna som ingår i systemet vara skräddarsydda för att hantera olika situationer. Detta betyder att varje enskild komponent måste individuellt kunna hantera stora simultana datamängder, samtidigt som de måste samarbeta med de andra komponenterna i systemet. För att underlätta snabb bearbetning av data mellan komponenter kan en modell, som specificerar informationsflödet och interna strukturer hos komponenterna, assistera i skapande av snabbare och mer tillförlitliga systemarkitekturer. I denna uppsats presenteras en modell för skapande av skalbara, säkra, tillförlitliga och bra presterande system som hanterar sensor-baserad data. En prototyp utvecklas, baserad på modellen, som kan hantera en stor mängd meddelanden från distribuerade sensorer. De olika komponenterna som används i prototypen utvärderas och deras för- och nackdelar presenteras. Resultatet visar att arkitekturen hos prototypen fungerar enligt de initiala kraven om hur bra systemet ska prestera. Genom att kombinera individuella styrkor hos komponenterna kan ett system skapas som tillåter stora mängder data att bli fördelat enligt deras typ, behandlat för att få fram relevant information och lagrat i en databas för enkel tillgång.
