The objective of this master thesis is the design, development, and deployment of a Peer to Peer system to track mobile entities in crowded events by using The SAPERE Approach, highlighting its theoretical and practical framework for decentralized deployment and execution of selfaware and adapting services. Our research is focused on the Spatial Computing Paradigm that in combination with Nature Inspired Coordination and The SAPERE Middleware, provide the abstractions needed to engineer complex interactions needed in emerging pervasive computing scenarios.
