The PERSEO aims to contribute to technical innovation by exploiting the potential of cooperative transmission and cross-layer techniques for wireless sensor networks. The main objectives of the project are:

• Definition of a network stack architecture able to accommodate a rich variety of sensor devices and applications.
• Analysis of possible Cross-Layer techniques that can be used in order to enhance the efficiency of wireless sensor networks.
• In-depth study of the potential benefits that can be obtained from using these techniques in different environments.
• Analysis of the trade-off between signalling overhead and enhanced performance in cross-layer approaches.
• Study of energy saving techniques based on cooperative diversity.
• Study of virtual MIMO (multiple input - multiple output) channels using individual SISO antennas of the sensor devices.
• Development of advanced, decentralized, self-organised MAC protocols that guarantee certain QoS for different scenarios.
• A demonstrator with standard wireless sensor devices will be implemented to assess the proposed algorithms in a real scenario.
• Dissemination of the project results contributing to technical journals and conferences in the course of the project lifetime.
