# This script is a simple TOSSIM test of dissemination.
# It builds a 15x15 grid of nodes and has nodes start
# disseminating two values (based on the TinyOS app).
# It prints out when nodes receive new values, including
# the dissemination key and sequence number. You should
# be able to see how the implementation can resolve
# multiple concurrent changes within the network as
# well as more than one value being updated at a time.
