The benefits of using Unmanned Aerial Vehicles (UAVs) as mobile sinks for data collection have attracted great attention in Wireless Sensor Networks (WSNs). The problem that computes the optimal trajectories for UAVs to collect data from WSN is generally NP-Hard. However, the existing works focus on the optimal trajectories of UAVs while considering the data transmission based on either predefined...
Soil characteristics are one of the most important evidential attributes for hydrologists and other environmental scientists to conduct domain-specific studies. To keep soil data complete is the first step towards analyzing soil characteristics. Usually collected by wireless sensor networks, however, the soil datasets often inevitably suffer significant and continuous data missing due to the unreliability...
This paper designs a wireless sensor mote platform, which harvests the micro environmental energy as its power source, and uses a fidelity-based energy policy to manage the working and recharging process of the sensor mote. Additionally a data collection and control framework is involved in this paper for practical account. A proof-of-concept prototype powered by the micro corrosion energy from the...
