### Simulated network with native
On native a IEEE 802.15.4 network is simulated by encapsulating 802.15.4 frames
inside UDP packets. For this the `socket_zep` modules is used both on the border
router and on the virtual mote.
The UDP packets are sent to a dispatcher which forwards them to all other nodes.
By default a simple dispatcher is provided that will forward every packet to
every node (perfect broadcast), but it can be replaced by the user with alternative
dispatchers to simulate more advanced topologies.
