Fwd: [Tinyos-help] error while incorporating interface CC2420Packet;

[Vijayant Bhatnagar]

Hi,
I would like to thank Greg for his quick reply. Right now, we don't have
real motes. Our plan is to get things working on TOSSIM (i.e. some kind of
simulation environment) for testing our protocol. We have already developed
Neighbor Discovery protocol and Routing protocols. We just need to give it a
final touch by analyzing how our protocols behave on different energy
levels.

We would be getting motes next month. By that time, we are planning to come
up with meaningful results and analysis.

Is there any software/simulation tool that can help us do this ?

Any help is appreciated.

Thanks again to Tinyos-help group!

Regards,
Vijayant
