I want a small IEEE 802.15.4 ZigBee WSN simulation using Castalia or Tossim .
The implementation is between two nodes, one is sensor and the other is sink node.
Sensor node is responsible of receiving "sound signal" from a sound "source" say microphone" through radio link " wireless connection.
Then sensor node send information about the sound signal to the sink node through wireless connection.
For the sound signal, we will use trace file of the sound.
