Global Positioning System (GPS) is het meest gekend, en een volwaardige oplossing voor plaatsbepaling buitenshuis. Dit systeem biedt echter geen oplossing voor plaatsbepaling binnenshuis. In deze thesis wordt een oplossing voor dit probleem aangeboden en getest in de praktijk.Er wordt gebruik gemaakt van een draadloos sensornetwerk om de positie te bepalen. De opstelling bestaat uit vaste referentienodes die hun positie kennen en een mobiele node waarvan de positie bepaald wordt. Bij het zenden van referentienode naar de mobiele node ontstaat er een verzwakking, welke gemeten wordt in de mobiele node aan de hand van de Received Signal Strength Indicator (RSSI).De RSSI kan opgemeten worden in functie van de afstand, welke een logaritmisch verband oplevert. Aan elke gemeten RSSI kan er dus een afstand gekoppeld worden.Met de berekende afstanden tussen de mobiele node en de referentienodes kan, in combinatie met een algoritme, de positie van de mobiele node bepaald worden.In deze thesis worden de algoritmes Multilateratie, Maximum Likelihood en MinMax getest en bestudeerd. Deze worden nadien op een originele manier, aan de hand van cumulatieve distributiefuncties, met elkaar vergeleken.Geen metingen zonder hardware, waarbij er in het eerste deel dan ook besproken wordt welke stappen ondergaan zijn om de hardware op punt te stellen. Global Positioning System is the most known, and complete solution for outdoor localisation. However, this system isn't a solution for indoor localisation. In this thesis, a solution to this problem is presented and tested in practice.We make use of a wireless sensor network in order to determine the position. The setup consists of fixed reference nodes that know their position, and a mobile node whose position is determined. During the transmission of reference node to the mobile node a transmission loss is created, which is measured in the mobile node by means of the Received Signal Strength Indicator (RSSI).The RSSI can be measured as a function of the distance, which produces a logarithmic relationship. Now each measured RSSI can be coupled to a distance.Using the calculated distances between the mobile node and the reference nodes, the mobile node's position can be determined in combination with an algorithm.In this thesis, the algorithms Multilateration, Maximum Likelihood and MinMax are tested and studied. These are then in an original way, on the basis of cumulative distribution functions, compared with each other.No measurements without hardware, which is also discussed in the first part. Hereby the steps to make the hardware up and running are also described.

Learn about designing, programming, and developing with the popular new Texas Instruments family of microcontrollers, the MSP430 series with this new book from Chris Nagy. This product line is experiencing explosive growth due to its low-power consumption and powerful features, but very little design and application information is available other than what is offered by the manufacturer. The book fills a gap in the technical literature for embedded systems engineers by offering a more complete combination of technical data, example code, and descriptive prose than is available from the manufa

MSP430 Microcontroller Basics combines a tutorial approach with a description of the CPU and main peripherals. It uses the C programming language from the start but programs are also developed in assembly language to show how a program interacts with the hardware. To demonstrate the special features of the MSP430 full coverage is given to the instruction set, sigma-delta analog-digital converters and timers. Finally, the book gives an introduction to the MSP430, which extends the architecture to address more memory and which provides a bridge to the ARM 7 processor.*Texas Instru
