Abstract :
This paper presents initial experiment results toward realizing a multi-core CPU for wireless sensor nodes. The multi-core CPU reduces power consumption with enabling users to easily manage hard real-time tasks. The results show a sensor node with triple CPUs can eliminate about 76 % of power consumption compared to a single CPU sensor node.
