Abstract

The dissertation presents an architecture and an implementation of efficient and personalized content dissemination service targeting mobile users. The service enables information publishers to publish the content for numerous users based on the publish/subscribe interaction style. Service personalization is achieved through subscriptions: Users define subscriptions to express their interest in receiving certain content types. The published content contains non-realtime data of variable bandwidth demands (short text messages, images or video clips) and the publishing time is usually randomly determined. Furthermore, the service enables personal mobility, i.e., a user can receive the content in various networks applying different terminals. The thesis investigates two aspects of content dissemination. Firstly, a mathematical model of distributed publish/subscribe systems is presented, followed by the definition of routing algorithms that support publisher and subscriber mobility. Secondly, the thesis proposes a software architecture for content dissemination services based on a designed publish/subscribe Web service.

Abstract (croatian)

Disertacija predlaže arhitekturu i implementaciju usluge za učinkovitu i personaliziranu isporuku sadržaja pokretnim korisnicima. Usluga omogućuje objavljivanje sadržaja na načelu objavi-pretplati namijenjenog velikom broju korisnika. Usluga je personalizirana jer korisnici pretplatom izražavaju interes za primanje određene vrste sadržaja. Sadržaj čine podaci koji se ne prenose u stvarnom vremenu, varijabilnih su prometnih karakteristika (kratke tekst poruke, slike ili video isječci), a trenutak njihovog objavljivanja je slučajni događaj. Usluga treba omogućiti pokretljivost osobe, tj. mogućnost primanja sadržaja u raznovrsnim mrežama i na različitim terminalima.
Disertacija daje dva pogleda na uslugu za isporuku sadržaja. Najprije je predložen matematički model koji opisuje distribuirane sustave objavi-pretplati, te su definirani algoritmi usmjeravanja poruka koji podržavaju pokretljivost korisnika sustava. Potom je predložena arhitektura usluge za isporuku sadržaja temeljena na komponenti objavi-pretplati koja je oblikovana primjenom tehnologije Web service.
