Abstract:
Mobile object tracking is the process of tracking objects which are moving constantly in their environment and thus change their location and context. We present in this paper a decentralized data management solution based on peer-to-peer (P2P) concepts and in particular a distributed hash table (DHT). Sensor network nodes run a DHT system, to which tracked objects or sensors insert their data about the objects. This distributed data storage can be queried by the application according to the DHT principles in order to retrieve the current status of an object without stability or bottleneck problems. Moreover, for scalability, our concept comprises a two tier architecture where we separate local tracking systems, which deal with frequent updates in a constrained local environment, and global tracking. In this way a second tier DHT based P2P system interconnects all local P2P systems for a global query resolution.
