So if I want to filter some message depending on a feature of the node(for example if the node ID is greater than 8,or depending on a variable stored in the node),what should I do ? a way to avoid trigger "Receive.receive" event. And how is about the energy consumption? If a node filter a message ,how much energy will save ?
Thanks.
