ZigBee performance in WSN

[Muhsin Atto]

Dear Yuri Tselishchev,

I been testing the performance of Zigbee with other WSN MAC and routing protocols for large number of nodes let say 50,100,200.
What I needed to figure out was  to draw a graph showing the performance of Zigbee against SMAC and LEACH according to the following aspects:
 - Total Received packets at sink
 - Latency
 - Consumed energy

I have asked this question in this forum before, but I have got any reply yet.   When I did the test I got the problem says (isChannelClear() function called when radio is NOT READY).  Please do you know what slould be the problem or do you have any ini file to test ZigBee ?

Any help is appreciated.
Muhsin
