Syftet med detta examensarbete är att undersöka möjligheten att skapa ett övervakningssystem där man tillämpar en passande teknologi på ett kreativt sätt. Applikationen som valdes är övervakning av dementa på ett ålderdomshem.Två tänkbara teknologier för utvecklingen av systemet, RFID och Bluetooth, studeras och analyseras. Efter en utvärdering väljs Bluetooth och används för att konstruera ett prototypsystem. Ett antal systemexperiment med kommunikationen mellan systemkomponenterna utförs och en analys genomförs för att bedöma teknologins effektivitet och användbarhet.Resultaten av systemexperimenten visar att det är möjligt att använda Bluetooth-teknologin för övervakning av människor inom ett visst bestämt område, till exempel ett ålderdomshem. Man kan detektera patienternas position och visa den för personalen på en datorskärm i en ritning över lokalerna.Detta arbete ska ses som en grund för en framtida utveckling och konstruktion av ett operationellt system. / The purpose of this thesis is to investigate the possibility of creating a monitoring system which applies a suitable technology in a creative way. The application chosen is the monitoring of persons with dementia in a retirement home.Two possible technologies that can be used for the development of the system, RFID and Bluetooth, are studied and analyzed. After the evaluation, Bluetooth is selected and used to construct a prototype system. A number of system experiments with the communication between system components is performed and an analysis carried out to assess efficiency and usability of the technologies.The results of the experimental system show that it is possible to use Bluetooth technology for the surveillance of people within a certain defined area, such as a retirement home. One can detect the position of patients and show it to staff on a computer screen in a plan of the premises.This work should be seen as a basis for future development and construction of an operational system.

This thesis provides an implementation of consensus of multi-agent networked systems. Consensus problem is an important issue of distributed computing and has various algorithms and applications in the field of electronical and computer science. The consensus requests all nodes of a network reach an agreement over a certain measurement. An algorithm of convergent consensus problem is implemented through a small network of Bluetooth communication in the thesis. The connections of the Bluetooth devices are wireless, and the device nodes of the network are driven by C++ software and Winsock API. The simulation results show that the implementation completes all the requirements of the distributed consensus algorithm.
