If you are referring to MICAz Mote, it has a 64-bit UID chip and thus offers 18,446,744,073,709,551,616 unique possibilities for identifying the nodes. You may include this into the packet header instead of 16-bit node ID that TOS packets contain. That is one option to consider.

According to cc22420 packet header we can have at most 2'16(bits) which makes 65,536 unique mote ids. How can we solve this problem? Is there a way to make mote address in cc22420 packet header more than 16 bits ? Or any other clever idea? Another way we can think of is to assign unique IDs within the customer network. However, in this case we need to pre-program the IDs and maintain a list of IDs used by the customer network. This makes additional sensor delivery process to customer more labor & time intense. If we pre-program a fixed ID (e.g 1) to all motes we ship, we can possibly program a new ID on the fly within the network (could you confirm and let us know how). In this case, if the networks of two customers are close in proximity to each other, we may run into interference problems (assume that all networks do the same thing and motes run the same program e.g. Collection). This brings up another question: what is the best and most power efficient way to distinguish 10,000 networks running the same application from each other. Sorry for the long email. Thanks a lot for all your comments. Mustafa ________________________________________________________________________ ____________ Looking for last minute shopping deals? Find them fast with Yahoo!
