Project: Paint it black

It is a well-known fact that Wireless Sensor Networks (WSNs) that are exposed to real environmental conditions suffer from harsh temperatures. Yet, the temperature does not only have negative impact as the energy effciency of processing units benefits from higher temperatures. The minimal voltage for correct operation of CMOS circuits is bounded by the temperature. Thus, temperature-dependent undervolting schemes for WSN nodes have been proposed in the past to extend the network lifetime. However, not much thought has been given into directly influencing the most relevant factor: Temperature. In this work we look at the influence of various WSN housings onto the temperature profile of WSN nodes and quantify the energy saving potential of choosing the right housing.
