application support, and architecture is required to build ultra low power systems. 5. CONCLUSION Designing hardware for wireless sensor networks requires a holistic approach looking at all areas of the design space. Proposed designs combine low power circuit tech- niques and hardware support for typical WSN tasks. Sys- tems researchers and domain practitioners are developing rich middleware and expanding the uses of WSNs, expect- ing more performance for less power out of the hardware platforms. Because the requirements for computation vary by several orders of magnitude, one-size-fits all hardware platforms will be difficult to develop. If designers choose to leverage technology scaling to provide more perfor- mance for less active energy consumption then an increase in leakage current will need to be addressed. With more research effort, we envision a future of WSNs made up of ultra low power nodes that provide high power computa- tion and can be deployed for decades. References 1. L. P. Alarcon, T.-T.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
