| Summary |
Solar-powered wireless sensor networks are attracting attention for outdoor long time operation such as
environmental monitoring. Even if sensor nodes are charged by solar energy, nodes far from the BS
(Base-Station) are stopped due to the lack of energy during nighttime. To prevent this problem, we consider the
use of cooperative transmission. In cooperative transmission, energy consumption is balanced among the nodes
because of the use of another node as a relay for data transmission of distant nodes. The conventional scheme
to select a relay node is based on available battery energy and the expectation of energy consumption of each
node. In this paper, we propose a relay selection scheme which is based on the prediction of harvested energy in
addition to the available battery energy and the expected value of energy consumption. We evaluate the
proposed scheme through packet delivery ratio and show its effectiveness. |
