While the potential benefits of sensingbased technology is real and significant, two major challenges remain in front of fully realizing this potential: resource-constrained sensors, especially the battery power, and decision making in real-time applications. In this thesis, we propose several data collection and analysis mechanisms that allow overcoming the limited sensor resources and the big data collection challenges imposed by sensing-based networks, under the clustering-based network architecture. Mainly, the proposed mechanisms work on three network levels (e.g. sensor, CH and sink), and they aim to reduce the amount of data routed in the network while preserving the information integrityat the sink. At the sensor level, we propose d...
