[ns] Energy consumption for mobile nodes not receiving/transmitting

[Salvo Danilo Giuffrida]

Hello, is it normal that a mobile node that does not transmit,
receive, or forward data in an ad-hoc network, consumes anyway energy,
just because it's in the range of two nodes communicating (in-between,
but it doesn't forward packets to or from them, they are able to talk
directly)?
Thanks a lot
