Individual Components of SN Nodes

SN nodes generally are composed of six components: processor; storage unit; power supply; sensors and/ or actuators; and, finally, communication (radio) subsystems. It is apparent that standard processors, possibly augmented with DSP, and other coprocessors and some ASIC units will provide adequate processing capabilities at acceptable low-energy rates. Also the state of the art of the actuators is such that they are still not used in the current generation of SN nodes. Therefore, the focus is on the other five components. For the sake of completeness, the discussion begins by presenting a processor specifically designed for sensor networks.
