A minimalist one-determinant tuning power scheme in wireless sensor networks

Transmission power control to save energy has been described in many studies to capture their efficiency. These previous methods, however, are too complicated, costing much communication, calculation, and require special hardware. Our simple method uses only one flooding to complete setting of all the nodes. The power is decided according to the hops from every node to the sink. The nodes with the same hops set equal power and they follow a tuning pattern. In this method there might exist the problem of unlinkedness for the sensor nodes. However, the problem of unlinkedness can be endured in WSNs. We explore the pattern to fit different simulated environments. The study shows that better results can be obtained if the hill and descending pattern with not too large slope are adopted.
