The advent of technology has facilitated the development of networked systems of extremely small, low power devices that combine programmable general purpose computing with multiple sensing and wireless communication capability. This networked system of pro-grammable sensor nodes, together form a sensor network , poses unique challenges on how information collected by and stored within the sens...
