What kind of configuration can I define so these group of similar node
id's do not send acks to unicast packets and somehow do not get involved
in the Collection process at all??(I have already taken out all the CTP
code from these nodes so they are only doing Dissemination) By disabling
acks, will it not cause a problem in Drip as it also relies on acks to
unicast packets???

Thanks for pointing to the TEP..... I could only find uptil TEP-127 from
the tinyos website...

Cheers,
Varun Jain

in the tree since they are not running the CTP code, the CTP packets
will be rejected at the link layer level itself. Am I right??? Also, I
just want to reiterate that the GROUP OF NODES with the same ID are not
doing any sensing and thus they are not running any CTP code....

Depending on how you are configuring the nodes, they might still send
acks to unicast packets.

there be a problem with "AM ID pools". I was reading the TEP-4 and I
cannot understand one thing: as an application developer, should we be
using the AM ID's in the range of 128-255 only though we are using it
for protocols???? Is it possible for you to send me the AM ID Allocation
list? Could this be a problem in my network??
