In wireless sensor networks (WSNs), consumption of energy is the major challenging issue. If the data is transmitted …

of comparing survey-reported and sensor-recorded cooking events, or durations of use, of improved cookstoves in two … also provide misleading qualitative findings on user-reported cookstove benefits without the support of sensor data …, causing us to overestimate impact. Some households with zero sensor-recorded usage reported cookstove fuel savings, quick …

Networking together hundreds or thousands of cheap sensor nodes allows users to accurately monitor a remote environment … by intelligently combining the data from the individual nodes. As sensor nodes are typically battery operated, it is … important to efficiently use the limited energy of the nodes to extend the lifetime of the wireless sensor network (WSN). One of …

that surveys of user behavior do not correlate well with sensor-measured behavior. The trial cookstove was much smaller and …

in sensor technology might address these challenges. In this study, we use sensors to describe solar light adoption in … Kenya and analyze the extent to which survey data are limited by systematic and random error. Sensor data reveal that … sensor measurements on average and differences are not correlated with household characteristics. However, mean …
