[Tinyos-help] unique mote id problem

[Giri Baleri]

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.

Subject: [Tinyos-help] unique mote id problem

Assume that we have 10,000 costumers and we will give each of them 10
mote which means we will have 100,000 motes distributed. 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.
