Description
This research was supported partially by Basic Science Research Programthrough the National Research Foundation of Korea (NRF) funded by theMinistry of Science, ICT & Future Planning (No. NRF-2016R1C1B10 15937),and by the MSIP(Ministry of Science, ICT and Future Planning), Korea,under the ITRC(Information Technology Research Center) support program(IITP-2017-2012-0-00646) supervised by the IITP(Institute forInformation & communications Technology Promotion).
abstract
A node in a solar-powered wireless sensor network (WSN) collects energy when the sun shines and stores it in a battery or capacitor for use when no solar power is available, in particular at night. In our scheme, each tiny node in a WSN periodically determines its energy budget, which takes into account its residual energy, and its likely acquisition and consumption. If it expects to acquire more energy than it can store, the data which has it has sensed is aggregated with data from other nodes, compressed, and transmitted. Otherwise, the node continues to sense data, but turns off its wireless communication to reduce energy consumption. We compared several schemes by simulation. Our scheme reduced the number of nodes forced to black out due to lack of energy so that more data arrives at the sink node.
