  • We propose the use of embedded in-wall thermoelectric harvester to power the nodes of a wireless sensor network. We exploit significant temperature differences of indoor and outdoor environments in cold climates. We use real measurements to evaluate the use of the temperature difference as a proxy to heat flow through walls, and the feasibility of creating a network of in-wall thermoelectric harvesting sensors. We also discuss the seasonal availability of thermoelectric energy and get in depth to the issues and advantages this presents. We formulate the corresponding multi-commodity routing flow problem, where each commodity is data from every node, and using the indoor/outdoor temperature as a proxy we investigate the effect of fairness in routing. We also present a low overhead method of constructing a seasonally-aware routing scheme and study its performance. Finally we talk about techniques for predicting the incoming available energy in the future.
