RESULTS In spite of a non-intuitive assumption regarding the PM and MM errors made as part of the derivation for PLIER, the resulting probe level error function does capture the key characteristics of the ideal error function, assuming MM probe...
متن کاملWhat does quality-aware data collection really achieve in energy harvesting wireless sensor networks?
Energy is the major bottleneck for wireless sensor networks. Although energy harvesting sensor nodes have emerged as a solution, new challenges in energy management arise due to the intermittently available energy. We also observe that many applications can tolerate certain levels of data inaccuracies. Here, we exploit the application’s tolerance for data inaccuracy to achieve an equilibrium be...
