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.
