[Tinyos-help] Power Consumption in CTP with LPL

[Atakan Bodur]

Hello,

I'm testing a network consisting of a single sensor node and a sink, in
which CTP is run with LPL. Meanwhile, I'm also measuring current in the
sensor node. I observe current of between 0.3 mA and 0.6 mA in sleep mode in
the first 10 minutes, but after that it increases to 3.0 – 3.5 mA and never
gets lower. When I restart the node, current is again low in first 10
minutes and increases to same values afterwards.

Sensor node transmits first data in second minute and after that it
periodically transmits in every 15-minute interval. Therefore, I do not
think of any event or action in the application to occur in tenth minute
causing such increase.

Does anyone have an idea about possible reasons of this increase? I would
appreciate any help.
