RE: [ns] error model in ad hoc

["jahn-isi" <jahn@ISI.EDU>]

Currently the probabilistic error module can be stacked over any propagation model such as
Two-ray or Shadowing model. The error module for wireless is independent of the propagation
models in that these propagtion models only compute the energy consumption
when signals arrive at the receiver as far as I know.

For details for inserting the error module just above the wireless-physical module, please refer
to the sample scenario file I provided under the test directory.

Hi,
I wonder if I can combine Two-ray Ground with Shadowing model or have to
use them separately.
For the new probablic error model, can I combine it with one of above or
use three together?

BTW, what's the meaning of those parameters in probablic model? such as,

ErrorModel/Trace set good_ 123456789
ErrorModel/Trace set loss_ 0
ErrorModel/Periodic set period_ 3.0
ErrorModel/Periodic set offset_ 0.0
ErrorModel/Periodic set burstlen_ 0.0
ErrorModel/MultiState set curperiod_ 0.0
ErrorModel/MultiState set sttype_ pkt
ErrorModel/MultiState set texpired_ 0

Thanks -- Dong
