%X Sensornets have been proposed consisting of thousands or
   tens of thousands of nodes. Economic and logistical
   considerations imply predeployment evaluation must take
   place through simulation rather than field trials. However,
   most current simulators are inadequate for networks with
   more than a few hundred nodes. In this paper we demonstrate
   some properties of sensornet application and protocols that
   only emerge when considered at scale, and cannot be
   effectively addressed by representative small\-scale
   simulation. We propose a novel multi\-phase approach to
   radio propagation modelling which substantially reduces
   computational overhead without significant loss in accuracy.
