Formelle forudsætninger:	In order to participate at this course you must be able to use all major elements of the Java language for implementing and testing medium sized programs, including threads, inheritance, packages, I/O, streams and serialisation. These competencies can be obtained by completing the first year of the B.Sc. in Software Development. ----- Information about the course of study Information om studiestruktur Dette kursus indgår på tredje semester på bacheloruddannelsen i software. ----- Information om kursusspærring Bemærk at der er kursusspærring mellem dette kursus og det tidligere kursus Distribuerede systemer og protokoller.
Læringsmål:	After the course you are expected to be able to: • describe and use fundamental architectures, principles and models used in designing and constructing mobile and distributed systems. • describe and use basic concepts in mobile and distributed systems for evaluation and designing of solutions to problems in the field. • implement distributed, and mobile systems in practice with the help of the above techniques.
Fagligt indhold:	Programs of today typically exhibit aspects of concurrency (or parallelism), distribution, or mobility or even all of them. In a concurrent system parts of the programs proceed simultaneously - for example in different threads or using event dispatching. In a distributed system parts of the system are spread over a number of programs communicating over a network to cooperatively provide a service. The network may be anything from the local network in a building to the entire Internet. Rather than studying specific vendors' tools and frameworks, we will be concerned with the theories that inevitably are the underpinnings of all vendors' solutions. In this course we will study some of the fundamental techniques used when developing, from a theoretical as well as from a practical point of view. In particular, the techniques are demonstrated throughout the course in lab assignments. However, note that this is an introductory course. This means that the course will not make you an expert in any of the above fields, but it will provide the foundation on which to continue with specialization courses or self-study. The course covers a number of topics, including: • Communication over the network leads to dropped and reordered packets which requires robust request/reply and multicast protocols. • Since programs communicate over an open and potentially faulty network, they must employ security, and it is difficult for them to synchronize on time, leaders, and data consistency. Protocols for encryption, authentication, authorisation, time synchronization, logical time, consensus, and data distribution address such issues. • In order to support changes and evolution of it-systems loosely coupled architectures such as Service Oriented Architecture are employed, as well as process-oriented architectures for combining services in process flows in an adaptable way. • Mobile and Ubiquitous computing has become widespread with the integration of computers and mobile phones and tablets like Android and iOS. Moreover, sensors based on RFID tags, bluetooth and GPS are becoming widespread – opening for new possibilities for applications such as location awareness, and new challenges for the implementations.
