Outline of Final Research Achievements

Wireless sensor networks (WSNs) that periodically collect the environmental information such as temperature, humidity, and so on require the coverage of a given target field any time and the operation lifetime longer than an expected duration by the minimum number of sensor nodes. For these WSNs, we propose two methods deciding a schedule of node movement to cover the agricultural field and water surface field, respectively.
For agricultural field, simulation results confirm that our method achieves 4% reduction of the number of nodes and 10% extension of the operation lifetime compared to the method without estimation of power generation amount. For water surface field, simulation results confirm that the proposed features for adjusting the positions of nodes moved by water current can improve the duration of field coverage by 48% for WSN with 360 nodes.
