MISSION 2012a channel model.
This model is an extension of the protocol channel model with per-link probability of detection and packet loss as measured from the MISSION 2012 experiment .
The node addresses and locations are also included in the class. Node addresses
can be accessed as
Mission2012a.nodes, and the (x, y, z) node location
in meters is access via the Map
