title: Set paramaters of Cooja Simulation
body: <p>I'm trying to do some simulation of the RPL protocol using Contiki 3.0 and the Cooja Simulator. I'm using the sky motes and i'd like to see how the DODAG is formed and monitor the parameters of the network using the Collect View. I have some questions:</p>
  
  <p>1) Where and how i can change the Objective function? </p>
  
  <p>2) My sensors have 1mW energy consumption, i think that for real application is too much, since sensors needs to work for several years</p>
  
  <p>3) Where i can change the other parameters of the simulation? Like Tx/Rx packets?</p>
  
  <p>4) How I interpret the routing metric given in the collect view?</p>
  
  <p>5) I noticed that when I change the position of a node the network is too much slow detecting the movement, RPL is not very fast, but in Cooja it takes too much time, is it possible? Do you have any suggestion for simulating moving sensors?</p>
