Abstract: This thesis aims to simulate a distributed sensor network for tracking objects, and to evaluate the performance and security of tracking algorithms in the implemented simulation. A distributed sensor network is composed of computer nodes that communicate wirelessly between each other, and with the base station. Based on the node positions, the base generates a geographic image about the network, and uses the network image to organize the network for the purpose of tracking objects entering the covered area of the sensor network. Existing self-organization algorithms for sensor networks tend to be inaccurate, and, in order to improve accuracy, may consume lots of energy, which is typically not affordable in wireless sensor nodes. I propose the development of new tracking methods, by applying techniques of image processing, such as border detection and skeletonization, to improve the accuracy of tracking objects in a sensor network. The proposed method, and some of the existing methods, will be evaluated in the simulated sensor network. Both performance and security issues will be investigated.
