Clustering algorithms for wireless sensor networks and security threats
Carlos Aleixandre Tudó · 2011
Since few years ago the interest of wireless sensor networks (WSNs) have been increasing. Furthermore a small battery sensors had appeared recently because of the miniaturization development. These new devices have a radio inside and a microprocessor, thus they can manage a big quantity of data. This new scenario has multiples advantages such as they can operate in hard conditions when the human can’t do or can be set up in a broad kind of systems to monitore and analyze the data. Sensors are randomly deployed over the terrain and they have to self-organize in a small groups to achieve a good power saving, scalability and routing. Thereby we need a new clustering sensor’s algorithms to organize these nodes in groups. In this thesis, we implement and test some clustering algorithms to obtain the latter features. We also study which are the security threats of our algorithm in order to see how vulnerable they are against malicious nodes and we will try to breakdown the system.
