| Research Abstract |
In this study, we proposed an autonomous geometric routing method that can decide a suitable base station (sink) and a route to reach the sink among multiple sinks and routes in a multi-sink wireless sensor network, in order to acquire sensed data from sensor nodes even if the wireless communications are unstable. In addition, a programmable wireless sensor node was developed as an implementation base to realize the proposed geometric routing. By introducing an ultra-low power FPGA (an LSI whose logic circuit can be customized by the user), it realizes both high-performance and low-power consumption, compared to the conventional wireless sensor nodes.
