|

*
|

* MRM is meant to be a replacement for the simpler radio mediums available in
|
||||
* COOJA. It is packet based and uses a 2D ray-tracing approach to approximate
|
||||
* signal strength attenuations between simulated radios. Currently the
|
||||
* ray-tracing only supports reflections and refractions through homogeneous
|
||||
* obstacles.
|
||||
*
|
||||
* MRM provides a number of plugins for example a plugin for visualizing radio
|
||||
* environments, and a plugin for configuring the radio medium.
|
||||
*
|
||||
* When a radio transmits data the area of interference around it will be
|
||||
* occupied for a time depending on the length of the packet sent. If the entire
|
||||
* transmission is completed without any interference the packet will be
|
||||
* delivered, otherwise nothing will be delivered.
|
||||
*
|
||||
* Future work includes adding diffractions and scattering support.
