Symbiotic Wireless Autonomous Powered system (SWAP) combines the nergy-efficient paradigm of wireless sensor networks with theself-sustainable capabilities of harvesting systems. SWAP aims at providing novel sensor board consisting of 1) a high efficiency RF transceiver 2) a low power micro controller 3) an energy accumulator 4) modular harvesting systems.
To this aim SWAP will study advanced solution for RF circuits and antennas, ill use state of the art micro controllers, will implement highlyefficient accumulator and will investigate on harvesting techniques. In articular, the different harvesting modules will be applied to standardsensor networks scenarios: for instance, environmental monitoring networks re more likely to use photo voltaic cells, while urban sensor networks canuse instead vibrations, and harvest the available ambient electromagnetic EM) energy.
SWAP will also study communication protocol from the physical to the etwork layer in order to implement the techniques offering the highestefficiency as well as taking into consideration the temporary availability f energy sources. Also, the SWAP system will be realized and tested on thefield; applications will be developed in order to provide the basic ervices for the new platform. As a final result, SWAP aims at obtaining anew wireless sensor paradigm totally independent from batteries and, oreover, having as little an impact on the environment as possible.
