Indeed, this gateway is on the path of all traffic going in or out the WSN. This traffic sample could be used to acquire a coarse estimate of individual nodes energy consumption.  ...  However, they still underestimate the consumption due to the routing control messages, to the packets strobing, or to contention and collisions and can easily be complemented by lightweight explicit calibrations  ...  However, RPL uses a Trickle algorithm [14] to dynamically adapt the emission interval of control messages.  ...
